In some of the liturgies St. Gabriel and St. Michael are jointly hailed as: champions and princes, leaders of the heavenly army; captains of the angels; servants of the divine glory; guardians and guides of human creatures. St. Gabriel is the Angel of the Annunciation. It was through him that the compliments of the Holy Trinity were addressed to Mary; that the mystery of the Trinity was first stated to man; that the Incarnation was announced; that the Immaculate Conception was declared; that the first notes of the Rosary were struck. ‘The scriptures show us one of the highest of heaven’s nobility sent in visible form to announce to Mary the mystery of the Incarnation. Mary was asked to become the Mother of God by an angel because by her divine motherhood she would hold sovereignty, power and dominion over all angels. ‘It can be said,’ writes Pope Pius XII, ‘that the Archangel Gabriel was the first heavenly messenger of the royal office of Mary.’” (Ad Coeli Reginam). Gabriel is honoured as patron of those who undertake important missions, who bear important news for God. He bore God’s message to Mary. In that moment she took the place of all mankind and he was representative of all the angels. Their dialogue, which will inspire men to the end of time, made a treaty on which will arise ‘new heavens and a new earth’. The united feast of Saints Michael, Gabriel and Raphael is celebrated on 29 September.
