Luke 3

Luke 3:22

And the Holy Ghost descended in a bodily shape like a dove upon him, and a voice came from heaven, which said, Thou art my beloved Son; in thee I am well pleased.

The Godhead are 3 distinct individuals. God the Father, Jesus Christ and the Holy Ghost. They are one in purpose. As members of the Church of Jesus Christ of Latter-day Saints we believe this to be so- Joseph Smith saw the Father and the Son, as separate personages, in a vision in the sacred grove.
