The Holy Trinity Revealed
In the Old Testament we find Yahweh, the one Lord and God, acting toward the world through His Word and His Spirit. In the New Testament the “Word becomes flesh” (Jn 1:14). As Jesus of Nazareth, the only-begotten Son of God becomes man. And the Holy Spirit, who is in Jesus making him the Christ, is poured forth from God upon all flesh (Acts 2:17).
One cannot read the Bible nor the history of the Church without being struck by the numerous references to God the Father, the Son (Word) of God and the Holy Spirit. The New Testament record, and the life of the Orthodox Church is absolutely incomprehensible and meaningless without constant affirmation of the existence, interrelation and interaction of the Father, the Son, and the Holy Spirit towards each other and towards man and the world.
