Glory to God in the highest. — The words would seem to have formed one of the familiar doxologies of the Jews, and, as such, reappear among the shouts of the multitude on the occasion of our Lord’s kingly entry into Jerusalem (Luke 19:38). The idea implied in the words “in the highest” (the Greek is plural), is that the praise is heard in the very heaven of heavens, in the highest regions of the universe.
On earth peace, good will toward men. — The better MSS. give, “on earth peace among men of good will” — i.e., among men who are the objects of the good will, the approval and love of God. The other construction, “Peace to men of peace,” which the Christian Year has made familiar, is hardly consistent with the general usage of the New Testament as to the word rendered “good will.” The construction is the same as in “His dear Son,” literally, the Son of His Love, in Colossians 1:13. The word is one which both our Lord (Matthew 11:25; Luke 10:21) and St. Paul use of the divine will in its aspect of benevolence, and the corresponding verb appears, as uttered by the divine voice, at the Baptism and Transfiguration (Matthew 3:17; Matthew 17:5). The words stand in the Greek, as in the English, without a verb, and may therefore be understood either as a proclamation or a prayer. The “peace on earth” has not unfrequently been connected, as in Milton’s Ode on the Nativity, with the fact that the Roman empire was then at peace, and the gates of the Temple of Janus closed because there was no need for the power of the god to go forth in defence of its armies. It is obvious, however, that the “peace” of the angels’ hymn is something far higher than any “such as the world giveth” — peace between man and God, and therefore peace within the souls of all who are thus reconciled. We may see a reference to the thought, possibly even to the words of the angelic song, in St. Paul’s way of speaking of Christ as being Himself “our peace (Ephesians 2:14).
