Answer:
God the Father
Step-by-step explanation:
When Jesus was baptized, immediately he went up from the water, and behold, the heavens were opened to him, and he saw the Spirit of God descending like a dove and coming to rest on him
The voice of God the Father: "This is,” according to Matthew, “My beloved Son, with whom I am well pleased” (Matthew 3:17) was an indication to John and the people present at the Divine dignity of the Baptized, as the Son of God, in the proper sense, The Only Begotten, on whom the grace of God the Father forever abides, and at the same time, as it were, the answer of the Heavenly Father to His Divine Son to His prayer for blessing for the great feat of service for the salvation of mankind.
The baptism of the Lord Jesus Christ also has the name Epiphany, because in this event all three hypostases of God appeared to the world: the Father in the form of a voice from heaven, the Son in the flesh of Christ, and the Holy Spirit in the form of a dove.
