We are the true adorers and the true priests, who, praying in spirit, sacrifice, in spirit, prayer,—a victim proper and acceptable to God, which assuredly He has required, which He has looked forward to for Himself! This victim, devoted from the whole heart, fed on faith, tended by truth, entire in innocence, pure in chastity, garlanded with love, we ought to escort with the pomp of good works, amid psalms and hymns, unto God’s altar, to obtain for us all things from God.
Tertullian
On Prayer
Chapter XXVIII
