God the Father
Christians who believe in the Trinity believe that God the Father is not a separate being or god from the other members of the Trinity; instead, they are distinct persons who are of the same essence and share the same qualities; because of this, the Son and Holy Spirit are no less "God" than the Father. According to Eastern Orthodox theology, God the Father is the arche or principium ("beginning"), the "source" or "origin" of both the Son and the Holy Spirit, and is considered the eternal source of the Godhead. The Father is the one who eternally begets the Son, and the Father, through the Son, eternally breathes the Holy Spirit.
