GOD THE FATHER
GOD THE FATHER is the fountainhead of the Holy Trinity. The Scriptures reveal that the one God is Three Persons-Father, Son, and Holy Spirit-eternally sharing the one divine nature. From the Father the Son is begotten before all ages and all time (Psalm 2:7; 2 Corinthians 11:31). It is also from the Father that the Holy Spirit eternally proceeds (John 15:26). Through Jesus Christ, and in the Holy Spirit, we come to know the Father (Matthew 11:27). God the Father created all things through the Son, in the Holy Spirit (Genesis 1; 2; John 1:3; Job 33:4), and we are called to worship Him (John 4:23). The Father loves us and sent His Son to give us everlasting life (John 3:16).
JESUS CHRIST is the Second Person of the Trinity, eternally born of the Father. He became a man, and thus He is at once fully God and fully man. His coming to earth was foretold in the Old Testament by the Prophets. Because Jesus Christ is at the heart of Christianity, the Orthodox Church has given more attention to knowing Him than to anything or anyone else.
In reciting the Nicene Creed, Orthodox Christians regularly affirm the historic faith concerning Jesus as they say,
“I believe . . . in one Lord Jesus Christ, begotten of the Father before all ages, Light of Light, Very God of Very God, begotten, not made, of one essence with the Father, by whom all things were made, who for us men and for our salvation came down from heaven, was incarnate of the Holy Spirit and the Virgin Mary, and was made man; and was crucified also for us under Pontius Pilate, and suffered and was buried; and the third day He rose again from the dead, according to the Scriptures; and ascended into heaven, and sits at the right hand of the Father; and He shall come again with glory to judge the living and the dead, whose Kingdom shall have no end.”
THE HOLY SPIRIT
THE HOLY SPIRIT is one of the Persons of the Trinity and is one in essence with the Father. Orthodox Christians repeatedly confess, “And I believe in the Holy Spirit, the Lord and Giver of life, who proceeds from the Father, who together with the Father and the Son is worshiped and glorified. . .” He is called the “Promise of the Father” (Acts 1:4), given by Christ as a gift to the Church, to empower the Church for service to God (Acts 1:8), to place God’s love in our hearts (Romans 5:5), and to impart spiritual gifts (1 Corinthians 12:7-13) and virtues (Galatians 5:22, 23) for Christian life and witness. Orthodox Christians believe the biblical promise that the Holy Spirit is given in chrismation (anointing) at baptism (Acts 2:38). We are to grow in our experience of the Holy Spirit for the rest of our lives.
