The Solemnity of the Most Holy Trinity is celebrated today. The first (recorded) time that God revealed Himself as a Trinity of Persons was at the Annunciation in Nazareth to the Blessed Virgin Mary. “Behold thou shalt conceive and bear a son; and thou shalt call his name Jesus. He shall be great, and shall be called the Son of the Most High. The Holy Ghost shall come upon thee, and the power of the Most High shall overshadow thee” (Lk. 1:31-32, 35).
