The Armenian Church accepts the first three ecumenical councils of the Christian Church. They are the Nicean Council (325 A.D.), the Council of Constantinople (381 A.D., and the Council of Ephesus (431 A.D.). Her doctrines are founded upon the creeds and the dogmas of these councils. The Nicean Creed is a major basis of the doctrine of the Armenian Church.

According to the Armenian Church, Christ is at one and the same time perfect God and perfect man. CHRIST IS GOD BECOME MAN. neither His divine nature nor His human nature are separated. These natures are united so that they are indivisible. Hence, we speak of the ONE NATURE of Christ (According to the formula of St. Cyril of Jerusalem).

The Armenian Church also believes that the Holy Spirit proceeds from the Father only.

The Armenian Church accepts the seven sacraments and the inspiration of the Holy Scriptures. She also has deacons, priests, bishops, and patriarchs. The Divine Liturgy is the supreme act of worship in the Armenian Church. She accepts both the Scriptures and tradition as legitimate rules of faith.
