The peculiarities of Luke's account o; the baptism are instructive. He omits the conversation between Jesus and John, and the fact of John's seeing the dove and hearing the voice. Like Mark, he makes the divine voice speak directly to Jesus, whereas Matthew represents it as spoken concerning Him. The baptism itself is disposed of in an incidental clause (having been baptized). The general result of these characteristics is that this account lays emphasis on the bearing of the divine witness as borne to Jesus Himself. It does not deny, but simply ignores, its aspect as a witness borne to John.
Another striking point is Luke's mention of Christ's prayer, which is thus represented as answered by the opened heavens, the descending dove, and the attesting voice. We owe most of our knowledge of Christ's prayers to this Evangelist, whose mission was to tell of the Son of man. Mysteries beyond our plummets are contained in this story; but however unique it is, it has this which may be reproduced, that prayer unveiled heaven, and brought down the dove to abide on the bowed head, and the divine attestation of sonship to fill the waiting heart.
We need not dwell on the beautiful significance of the emblem of the dove. It symbolised both the nature of that gracious, gentle Spirit, and the perpetuity and completeness of its abode on Jesus. Others receive portions of that celestial fullness, but itself, as if embodied in visible form, settled down on Him, and, with meekly folded wings, tarried there unscared. God giveth not the Spirit by measure unto Him.'
Our Evangelist does not venture into the deep waters, nor attempt to tell what was the relation between the Incarnate Word, as it dwelt in Jesus before that descent, and the Spirit which came upon Him. We shall be wise if we refrain from speculating on such points, and content ourselves with knowing that there has been one manhood capable of receiving and retaining uninterruptedly the whole Spirit of God; and that He will fill us with the Spirit which dwelt in Him, in measure and manner corresponding to our need and our faith.
The heavenly voice spoke to the heart of the man Jesus. What was His need of it, and what were its effects on Him, we do not presume to affirm. But probably it originated an increased certitude of the consciousness which dawned, in His answer to Mary, of His unique divine sonship. To us it declares that He stands in an altogether unexampled relation of kindred to the Father, and that His whole nature and acts are the objects of God's complacency. But He has nothing for Himself alone, and in Him we may become God's beloved sons, well pleasing to the Father.
