St. Ambrose was a 4th century bishop. He refuted Arianism, which proposed that Jesus Christ was not co-eternal with God the Father, and therefore was subject to the Father. He is also credited with antiphonal chant, in which one side of a congregation chants one part of a song or psalm, and then the other side responds. This is sometimes done in Liturgy of the Hours, where the psalms are chanted or recited in this manner.
St. Ambrose is the patron saint of bee keepers, bishops, domestic animals, police, and students. His feast day is December 7.
