EWTN Catholic Q&A
Question from Dennis P. McGeehan on 11-07-2012:

Since Jesus is truly present in the tabernacle, how many angels do we think are constantly in his presence at the tabernacle of each Catholic Church?

Answer by Fr. John Echert on 11-12-2012:

I wish I knew but have no answer. It could be a multitude or it could be a smaller number. Considering how many tabernacles there are worldwide, I suppose it may depend upon the total number of angels who are assigned to this honorable duty.

Thanks, Dennis

Father Echert
