Nestorian Christians are members of a Christian sect that originated in Asia Minor and Syria in the 5th century C.E.. Their beliefs include:
Separation of Christ's natures
Nestorians believe that Christ's human and divine natures are separate and independent, and that they are two people loosely joined together.
Mary as the Mother of Christ, not the Mother of God
Nestorians believe that Mary was the mother of Christ, but not the Mother of God, because that would make her superior to Christ.
Jesus as a man, not divine
Nestorians believe that Jesus was a man, not divine, because Mary was only his mother.
Nestorianism became a schismatic sect after the ecumenical councils of Ephesus (431 CE) and Chalcedon (451 CE) condemned Nestorius and his teachings. Nestorianism spread to China, India, Egypt, and Central Asia, where some tribes were almost entirely converted.
Today, Nestorians are represented by the Church of the East, also known as the Persian, Assyrian, or Nestorian church. Most of its members live in Iraq, Syria, and Iran.
