On the Feast of Michael and all Angels, popularly called Michaelmas, we give thanks for the many ways in which God’s loving care watches over us, both directly and indirectly, and we are reminded that the richness and variety of God’s creation far exceeds our knowledge of it.
The Holy Scriptures often speak of created intelligences other than humans who worship God in heaven and act as His messengers and agents on earth. We are not told much about them, and it is not clear how much of what we are told is figurative. Jesus speaks of them as rejoicing over penitent sinners (Lk 15:10). Elsewhere, in a statement that has been variously understood (Mt 18:10), He warns against misleading a child, because their angels behold the face of God. (Acts 12:15 may refer to a related idea.)
