St. Gabriel the Archangel in the Gospel of Luke relates the stories of the Annunciation, in which the angel Gabriel appears to Zechariah and the Virgin Mary, foretelling the births of John the Baptist and Jesus.
Gabriel means -“Fortitudo Dei” — meaning “Power and Might God” or “God’s Strength” and is one of the three archangels mentioned in the Scriptures, appearing in both the Old and New Testament. He is known as the angel of the Incarnation and of Consolation.
The trope of Gabriel the Archangel blowing a trumpet blast to indicate the Lord’s return to Earth is especially familiar in Spirituals. However, though the Bible mentions a trumpet blast preceding the resurrection of the dead, it never specifies Gabriel as the trumpeter.
The feast of Saint Gabriel was included by Pope Benedict XV in the General Roman Calendar in 1921, for celebration on 24 March. It is unknown whether this was a temporary change, however there is no recent mention of the feast commemoration between the years 1921 and 1969. In 1969 the day was officially transferred to 29 September for celebration in conjunction with the feast of St. Michael and St. Raphael.
