"Fortitudo Dei", one of the three archangels mentioned in the Bible. Only four appearances of Gabriel are recorded:
* In Dan., viii, he explains the vision of the horned ram as portending the destruction of the Persian Empire by the Macedonian Alexander the Great, after whose death the kingdom will be divided up among his generals, from one of whom will spring Antiochus Epiphanes.
Thus he is throughout the angel of the Incarnation and of Consolation, and so in Christian tradition Gabriel is ever the angel of mercy while Michael is rather the angel of judgment. At the same time, even in the Bible, Gabriel is, in accordance with his name, the angel of the Power of God, and it is worth while noting the frequency with which such words as "great", "might", "power", and "strength" occur in the passages referred to above. The Jews indeed seem to have dwelt particularly upon this feature in Gabriel's character, and he is regarded by them as the angel of judgment, while Michael is called the angel of mercy. Thus they attribute to Gabriel the destruction of Sodom and of the host of Sennacherib, though they also regard him as the angel who buried Moses, and as the man deputed to mark the figure Tau on the foreheads of the elect (Ezech., 4). In later Jewish literature the names of angels were considered to have a peculiar efficacy, and the British Museum possesses some magic bowls inscribed with Hebrew, Aramaic, and Syriac incantations in which the names of Michael, Raphael, and Gabriel occur. These bowls were found at Hillah, the site of Babylon, and constitute an interesting relic of the Jewish captivity. In apocryphal Christian literature the same names occur, cf. Enoch, ix, and the Apocalypse of the Blessed Virgin.
As remarked above, Gabriel is mentioned only twice in the New Testament, but it is not unreasonable to suppose with Christian tradition that it is he who appeared to St. Joseph and to the shepherds, and also that it was he who "strengthened" Our Lord in the garden (cf. the Hymn for Lauds on 24 March). Gabriel is generally termed only an archangel, but the expression used by St. Raphael, "I am the angel Raphael, one of the seven, who stand before the Lord" (Tob., xii, 15) and St. Gabriel's own words, "I am Gabriel, who stand before God" (Luke 1, 19), have led some to think that these angels must belong to the highest rank; but this is generally explained as referring to their rank as the highest of God's messengers, and not as placing them among the Seraphim and Cherubim (cf. St. Thomas, I, Q. cxii, a.3; III, Q. xxx, a.2, ad 4um).
