“Now when all the people were baptized, and when Jesus also had been baptized and was praying, the heaven was opened, and the Holy Spirit descended in bodily form like a dove upon Him, and a voice came from heaven which said, ‘You are My beloved Son; in You I am well pleased.’” (NRSV Luke 3:21-22)
The Holy Spirit did not appear in the form of a dove… rather, the Spirit appeared in “bodily form” and the way the Jewish writer chose to describe this amazing vision was… “like a dove.”
