The Advent of Trinitarian Christianity

The Christian school of Alexandria tapped into a long legacy of learning based in that city. During the 3rd Century B.C. its Greek Ptolemaic rulers constructed one of the largest and most important libraries in the ancient world. For centuries Alexandria functioned as a major center of philosophy and learning.

The Alexandrian school became the center for this Platonist perspective in Christianity, which emphasized the spiritual and downplayed the empirical. The Alexandrians liked to quote Paul(c. 4 B.C.–A.D. 64) Apostle and early Christian missionary, whose letters are the earliest documents contained in the New Testament and thus the first extant writings in Christian theology. more: “the letter killeth, but the spirit giveth life.”2 They accused their opponents in AntiochA large and important city in Syria and the meeting point of the East and West. more, who read the scriptures literally, of killing the true gospel message.

The dispute carried on, each school writing polemic literature defending their “correct” approach and attacking the other. The Antiochians strove to separate the divine and human nature of Jesus(c. 4 B.C.–A.D. 30-33) Also known as Jesus of Nazareth, Jesus Christ, the Messiah, and Savior of the World.

This dispute in Alexandria spread and involved the whole empire. Bishops as far away as Spain felt obliged to opine on the issue. It became so hotly contested that Christians were ridiculed by their pagan neighbors. Here is how one ancient record describes the atmosphere at the time:
“Everywhere in the public squares, at the crossroads, on the streets and lanes, people would stop you and discourse at random about the trinity. If you asked something of the moneychanger, he would begin discussing the question of the Begotten and Unbegotten. If you questioned a baker about the price of bread, he would answer that the Father was greater and the Son is subordinate to him. If you went to take a bath, the Anomoean bath attendant would tell you that in his opinion the Son came from nothing.”3
Another ancient historian wrote:
“The workmen in the port, the sailor, the idle and the common people in the street knew these songs [written by Arius], and assailed the ears of the faithful of Alexandria with them. Whence endless fights… The public was interested in these questions, even the pagan public, who, be it well understood, made use of the occasion to amuse themselves at the expense of the Christians and of their beliefs. The quarrel of Arius(c. 256-336) Alexandrian presbyter whose teaching on the Trinity was condemned at the Council of Nicaea A.D. 325.

Platonic Influence
We may wonder why this was such a heated debate. To us it may appear that they were quibbling over mere words, but such an assumption would be a mistake. To them, they were arguing over the very nature of God and their own personal salvation.
Christianity sprang from Jewish and Greco-Roman parents, and its religious and cultural DNA came from those roots. Christianity began as a Jewish sect in a Greco-Roman world, and both influences contributed to the debate regarding the nature of God leading up to the Council of Nicaea.
The Greco-Roman world held a schizophrenic view of divinity. On one hand, the ideas of various monotheistic philosophical schools prevailed in rational discussions while the myths of the pantheons of gods dominated social religious practice. Christians adopted, or at least adhered to, many of the philosophical concepts accepted by educated Romans, while they rejected wholesale the pagan gods whom the Christians viewed as not only false myths but as demons or stories created by the devil.

The philosophical ideas that influenced Christianity began with Heraclitus (550–480 BCE). He introduced the idea of the Logos as the universal mind that permeated everything and was the source of harmony and order in the universe. The word logosIs a Greek word meaning “word,” “reason.” and “logic.” It was an important concept in Greek philosophy. St. John opened his gospel identifying Christ as the Logos and is a key concept in Trinitarian debate. Logos Christianity refers to the... more literally means “word” but it developed a much broader meaning over the centuries leading up to the birth of Christianity. Socrates(470–399 B.C.).

Judaism was the first recorded monotheistic religion. Over millennia its leaders made a concerted effort to combat the polytheistic influences in the world around them. Yet the concept of the Logos played a role in its theology. The Aramaic term memra, which interpreted means “the Word,” was found throughout the Targums (Rabbinical writings that interpreted the Hebrew Bible) leading up to the time of ChristDerived from a Greek term meaning anointed and is equivalent to the word “messiah” from Hebrew roots. The anointing references the act of installing a new king similar to the modern custom of crowning a king, so the term “Christ”... more. This term is often used as a substitute for the name of God in scriptures dealing with the creation and the source of wisdom such as the Book of Proverbs. The Platonist Jewish philosopher Philo(c. 20 B.C.–A.D. 50) Jewish philosopher and exegete who used an allegorical method to interpret the scriptures that was influential on ancient Christian writers, especially in Alexandria. more of Alexandria used the concept of Logos extensively. He taught that the Word was a shadow of God that He used to create the world and the second most universal thing after God. The Word was not like the uncreatedThis is a technical theological term originating in Greek philosophy that is used to determine what is eternal and divine and what was created by the divine. The premise is that everything is either created by God or is God... more God but was also not like created humans; the Logos existed in a state between both. He combined Jewish ideas with Platonist concepts to claim that the Logos was the sum total of all ideas in this intelligible world, God’s creative word, and His revelator. By the time Christianity was born, some Jews shared the Greco-Roman view that the Logos, the Word of God, was a life force that enabled the creations of their monotheistic God to move, breathe and exist. This concept was generally accepted by the Christian community.

These concepts were not new to his Jewish or Gentile audience. What was revolutionary was his assertion that: “The Word was made flesh, and dwelt among us.” (JohnJohn (c.

Logos Theology
The earliest Christian apologist Justin Martyr(c.A.D 100–165) Born in Palestine early in the 2nd century, Justin was educated as a philosopher and converted to Christianity, retaining many of his Platonist convictions.

One of the main doctrines taught by Justin (which later became central to the debate that birthed to the Council of Nicaea and also a key component of the mystery of the Trinity), was the timing of the Son’s creation. According to Justin, God the Father, who existed outside time, created the Son by his own will and power as the first step in the creative process. Even though the Father existed prior to the Son, the Logos (ChristDerived from a Greek term meaning anointed and is equivalent to the word “messiah” from Hebrew roots.

Sabellian Heresy
A Trinitarian dispute occurred around A.D. 220 when a priest named Sabellius(c.

This view of the trinity was condemned, holding... more argued that the godhead did not consist of three separate persons but instead was one entity working through three different modes or aspects: creation through the Father, redemption through the Son, and sanctificationDerived from the Latin word sanctus for “holy” and literally means “becoming holy.” In most Protestant theology it refers to the process of become a more moral individual through an internal transformation following justification that occurs at the time of... more through the Holy Spirit. His teachings emphasized the unity and absolute divinity and greatness of God and held that dividing God into three separate persons diminished his greatness. His ideas at first gained favor with some theologians, including the Pope, but were soon rejected by the Pope and most Christians, who continued to hold to a belief in the distinct personhood of the Father, the Son and the Holy Spirit. This heresyComes from a Greek term meaning “sect,” and was used by the early Church theologians to identify doctrines that they rejected as not orthodox. The term does not refer to unbelief but ideas held by some baptized Christian that was... more in its general application is variously referred to as Sabellianism, Modalistic Monarchianism and Patripassianism.

The Arian Controversy

Arius(c. 256-336) Alexandrian presbyter whose teaching on the Trinity was condemned at the Council of Nicaea A.D. 325.

To combat their opponents’ claim that the Father and Son are one, Arius quoted JohnJohn (c.

Church History in Plain Language
by Bruce Shelley and Marshall Shelley
Bruce Shelley's classic history of the church brings the story of global Christianity into the twenty-first century. Like a skilled screenwriter, Shelley begins each chapter with three elements: characters, setting, plot. Taking readers from the early centuries of the church up through the modern era he tells his readers a story of actual people, in a particular situation, taking action or being acted upon, provides a window into the circumstances and historical context, and from there develops the story of a major period or theme of Christian history. Covering recent events, this book also: Details the rapid growth of evangelical and Pentecostal Christianity in the southern hemisphere; Addresses the decline in traditional mainline denominations; Examines the influence of technology on the spread of the gospel; Discusses how Christianity intersects with other religions in countries all over the world. For this fifth edition, Marshall Shelley brought together a team of historians, historical theologians, and editors to revise and update this father's classic text. The new edition adds important stories of the development of Christianity in Asia, India, and Africa, both in the early church as well as in the twentieth and twenty-first centuries. It also highlights the stories of women and non-Europeans who significantly influenced the development of Christianity but whose contributions are often overlooked in previous overviews of church history. This concise book provides an easy-to-read guide to church history with intellectual substance. The new edition of Church History in Plain Language promises to set a new standard for readable church history.

On Classical Trinitarianism: Retrieving the Nicene Doctrine of the Triune God
by Matthew Barrett, Ed.
Modern theology claimed that it ignited a renaissance in trinitarian theology. Really, it has been a renaissance in social trinitarianism. Classical commitments like divine simplicity have been jettisoned, the three persons have been redefined as three centers of consciousness and will, and modern agendas in politics, gender, and ecclesiology determine the terms of the discussion. Contemporary trinitarian theology has followed the spirit of this trajectory, rejecting doctrines like eternal generation which were once a hallmark of Nicene orthodoxy and reintroducing subordinationism into the Trinity.

If you’re a student of Greek, you’ll appreciate this handy volume. It gives you the complete Septuagint text in parallel columns with Brenton’s English translation.

The Two Treatises of Servetus on the Trinity
by Michael Serveto
One of the most radical dissenters of the early Protestant Reformation was Michael Servetus (1511-1553), who set forth his antitrinitarian beliefs in his best known work, On the Errors of the Trinity, in 1531. He believed that Christ less than God the Father, yet still divine, similar to Arius. He spent most of his life running from both the Catholic Inquisition and the Protestant Reformers. He was captured and put to death in 1553.
The Racovian Catechism: With Notes and Illustrations,
Translated from the Latin; To Which Is Prefixed a Sketch of the History of Unitarianism in Poland and the Adjacent Countries
Faustus Socinus introduced a second stream of anti-trinitarianism that held Christ was not of a lesser divinity than God as Arius taught, but was fully human. He wrote a number of works, but his Racovian Catechism is perhaps the best well-known. He fled persecution in Italy and went on to inspire the founding of the Polish Brethren, which largely inspired the Unitarian movement.
The Golden Thread: A History of the Western Tradition, Volume I: The Ancient World and Christendom
by James Hankins and Allen C. Guelzo
"...a monumental work of reclamation and revival...The Golden Thread comes as a history, an argument, a treasure hoard." — The Wall Street Journal. It is a sweeping, resource-rich history of the ancient world and Christendom—designed for students and lifelong learners alike, and faithful to the enduring legacy of the Western tradition. This is Volume I of a two-part series tracing the story of Western civilization from antiquity to the modern age. Where do the threads that form the Western tradition originate, and how were they woven together over the two and a half millennia before A.D. 1500? What are the sources of our modern ideas about science, freedom, equality, law, good government, and virtue? These are the questions explored in The Golden Thread, Volume I: The Ancient World and Christendom. The story begins with the seminal culture of the classical Greeks and moves through the Hellenization of the east following the conquests of Alexander the Great. Hankins then narrates the rise and dominance of Rome and the fusion of Greco-Roman and Judea-Christian cultures in the Christian empire of the fourth century AD. The volume follows the history of Christendom from the fall of the Western Roman Empire, charts its centuries-long rivalry with the Islamic world, and culminates in the emergence of European civilization in the Middle Age and Renaissance. Written by two of the most distinguished historians of our time. It includes nearly 1000 curated images—sculptures, paintings, and artifacts—from the vaults of the West’s finest cultural institutions. Readers are not merely told what happened, but shown what was created—page after page alive with the rich architecture, sculpture, music, and painting and maps that gave visible form to the West’s most enduring aspirations.

What Christians Believe: Understanding the Nicene Creed
by Robert Barron
Today, more than a quarter of Americans claim no religious affiliation at all. Religious belief in general, and Christianity in particular, is increasingly regarded as mythical and unreasonable—the superstitious product of prescientific minds. But what do thoughtful Christians actually believe? In this short book, renowned preacher, teacher, and theologian Bishop Robert Barron invites skeptics, seekers, and lifelong Christians alike to consider this question through one of Christianity’s most pivotal texts: the Nicene Creed, an ancient statement of faith that has guided Christian thought for 1700 years and is still accepted by Christians around the world today. With philosophical and theological acumen, Bishop Barron walks through the Creed line by line, explaining its teachings on the mystery of the Trinity, the saving mission of Jesus Christ, and both the life of the Church below and the life of the world to come. Drawing on Sacred Scripture, Church teaching, and the richness of the Catholic intellectual tradition, What Christians Believe unfolds the essentials of the Christian faith with conviction and clarity.
Ancient Christianities: The First Five Hundred Years
by Paula Fredriksen
How, over the course of five centuries, one particular god and one particular Christianity came to dominate late Roman imperial politics and piety. The ancient Mediterranean teemed with gods. For centuries, a practical religious pluralism prevailed. How, then, did one particular god come to dominate the politics and piety of the late Roman Empire? In Ancient Christianities, Paula Fredriksen traces the evolution of early Christianity—or rather, of early Christianities—through five centuries of Empire, mapping its pathways from the hills of Judea to the halls of Rome and Constantinople. The New Testament, as we know it, represents only a small selection of the many gospels, letters, acts of apostles, and revelations that circulated before the establishment of the imperial church. It tells how the gospel passed from Jesus, to the apostles, thence to Paul. But by using our peripheral vision, by looking to noncanonical and paracanonical texts, by availing ourselves of information derived from papyri, inscriptions, and archaeology, we can see a different, richer, much less linear story emerging. Fredriksen brings together these many sources to reconstruct the lively interactions of pagans, Jews, and Christians, tracing the conversions of Christianity from an energetic form of Jewish messianism to an arm of the late Roman state.
Catholicism: A Journey to the Heart of the Faith
by Robert Barron
What is Catholicism? A two-thousand-year-old living tradition? A worldview? A way of life? A relationship? A mystery? In Catholicism, Bishop Robert Barron examines all these questions and more, seeking to capture the body, heart, and mind of the Catholic faith. Starting from the essential foundation of Jesus Christ’s Incarnation, life, and teaching, Bishop Barron moves through the defining elements of Catholicism—from sacraments, worship, and prayer, to Mary, the Apostles, and saints, to grace, salvation, heaven, and hell—using his distinct and dynamic grasp of art, literature, architecture, personal stories, Scripture, theology, philosophy, and history to present the Church to the world. Paired with his documentary film series of the same title, Catholicism is an intimate journey capturing “the Catholic thing” in all its depth and beauty. Eclectic, unique, and inspiring, Bishop Barron brings the faith to life for a new generation in a style that is faithful to timeless truths while simultaneously speaking in the language of contemporary life.
