St. Gabriel is one of seven archangels who enter and serve before the Glory of the Lord, and one of the three archangels mentioned in Sacred Scripture: Gabriel (Luke 1:27-28).
The name Gabriel means “Man of God” in Hebrew or “God has shown might.”
In Gabriel’s best known and most celebrated appearance, he announced to Mary that she would bear a son, who would be conceived of the Holy Spirit, and would be called Son of the Most High, and Savior of the World. (Luke 1:26-38) Gabriel may have been the unnamed angel, who appeared to St. Joseph in his sleep and instructed Joseph not to divorce Mary quietly. He explained that Mary’s child was conceived by the power of the Holy Spirit and that He would be named Emmanuel, which means God is with us. (Matthew 1:20-24)
