"In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God" (John 1:1-2).
Critics often have declared that the Bible contradicts itself in matters relating to the Trinity. For example, Genesis speaks of God's creating the heavens and the earth. The New Testament declares that the Word - God the Son - created all things. Still other references speak of the Holy Spirit's work in creation. These are not contradictions. Father, Son, and Spirit worked together in the miracles of creation, just as they worked together in the planning and effecting of human redemption. The Father, Son, and Holy Spirit are consubstantial ... one in substance and cannot be separated.
When Jesus was to launch His earthly ministry, He went to John at the Jordan River to be baptized. The record speaks of the Trinity's involvement. As Jesus stood on the bank of the river following His baptism, the Holy Spirit descended as a dove upon Him and the voice of God the Father was heard from heaven saying, "This is my beloved Son, in whom I am well pleased" (Matthew 3:17).
Praise God from whom all blessings flow;
Praise Him, all creatures here below;
Praise Him above, ye heavenly host;
Praise Father, Son and Holy Ghost. Amen
