## God is Trinity

Orthodox Christians believe in one God in three Persons: Father, Son and Holy Spirit. The Son of God became incarnate of the Virgin Mary, suffered, rose and will come to judge the living and the dead.

## The Church and salvation

The Church is the Body of Christ, in which a person is united with God through the sacraments. The aim of life is deification, participation in divine grace.

## Sources of the faith

Holy Scripture and Holy Tradition (the decisions of the Councils, worship, the writings of the Fathers) form a single whole.
