እግዚአብሔር በአንድነቱ አንድ ነው (God is One in Essence)

The mystery of the Holy Trinity is the central dogma of the Church. It states that God is one in essence and three in persons.

This teaching is derived directly from the Holy Scriptures and the councils of the early Church fathers, who combated heresies that sought to diminish the divine nature of the Trinity.
