Coptic

A branch of Christianity that was excluded from the Catholic and Orthodox traditions in the Council of Chalcedon in A.D. 451 that dealt with the incarnation of Christ. The Church in Alexandria, Egypt, that based on credible legend was founded by the Apostle Mark, maintained that Christ has one nature derived by his two natures, divine and human, while the Council held that Christ is one person with two natures, divine and human.
