On Angels and Prayer

Blessed Augustine of Hippo ca. 354-430

For, even when His angels hear us, it is He Himself who hears us in them, as in His true temple not made with hands, as in those men who are His saints; and His answers, though accomplished in time, have been arranged by His eternal appointment. (City of God Bk. 10.12)

Or perhaps that they [prayers] may be made known also to the angels that are in the presence of God, that these beings may in some way present them to God, and consult Him concerning them, and may bring to us, either manifestly or secretly, that which, hearkening to His commandment, they may have learned to be His will, and which must be fulfilled by them according to that which they have there learned to be their duty; for the angel said to Tobias: Tobit 12:12 Now, therefore, when you prayed, and Sara your daughter-in-law, I brought the remembrance of your prayers before the Holy One. (Letter 130.9.18)
