Orthodox Christians worship the Father, Son, and Holy Spirit—the '''Holy Trinity''', the one [[God]]. Following the [[Holy Scriptures]] and the [[Church Fathers]], the Church believes that the Trinity is three divine persons (''[[hypostasis|hypostases]]'') who share one essence (''[[ousia]]''). It is paradoxical to believe thus, but that is how God has revealed himself. All three persons are consubstantial with each other, that is, they are of one essence (''[[homoousios]]'') and coeternal. There never was a time when any of the persons of the Trinity did not exist. God is beyond and before time and yet acts within time, moving and speaking within history.

God is not an impersonal essence or mere "higher power," but rather each of the divine persons relates to mankind personally. Neither is God a simple name for three gods (i.e., polytheism), but rather the Orthodox faith is monotheist and yet [[Triadology|Trinitarian]]. The God of the Orthodox Christian Church is the God of [[Abraham]], [[Isaac]] and [[Jacob]], the '''I AM''' who revealed himself to [[Moses]] in the burning bush.
