(22) In a bodily shape.--The words are peculiar to St. Luke, and tend to confirm the traditional symbolism which finds in the dove the emblem of the Holy Spirit. They, at least, fall in naturally with this view; but the other construction, that the Holy Spirit descended, after the manner of a dove, first hovering and then resting, in a bodily form (undefined) of some sort, is, at least, not excluded.

3:21,22 Christ did not confess sin, as others did, for he had none to confess; but he prayed, as others did, and kept up communion with his Father. Observe, all the three voices from heaven, by which the Father bare witness to the Son, were pronounced while he was praying, or soon after, Lu 9:35; Joh 12:28. The Holy Ghost descended in a bodily shape like a dove upon him, and there came a voice from heaven, from God the Father, from the excellent glory. Thus was a proof of the Holy Trinity, of the Three Persons in the Godhead, given at the baptism of Christ.And the Holy Ghost descended in a bodily shape,.... In a corporeal form, in a visible manner, and was seen with bodily eyes, at least by John the administrator; to whom this was a signal of his being the Messiah, and a fresh confirmation of it:

like a dove upon him; either in the form of a dove, or this corporeal form, whatever it was, descended and hovered on him as a dove does:

and a voice came from heaven; at the same time the Holy Ghost came down upon him; which said,

thou art my beloved Son, in thee I am well pleased: and was the voice of the Father; and the whole of this was an answer of Christ's prayer; See Gill on Matthew 3:16, Matthew 3:17, Mark 1:11.
