1 I have long been wishing, O true-born and dearly beloved children of the Church, to discourse to you concerning these spiritual and heavenly Mysteries; but since I well knew that seeing is far more persuasive than hearing, I waited for the present season; that finding you more open to the influence of my words from your present experience, I might lead you by the hand into the brighter and more fragrant meadow of the Paradise before us; especially as you have been made fit to receive the more sacred Mysteries, after having been found worthy of divine and life-giving Baptism. Since therefore it remains to set before you a table of the more perfect instructions, let us now teach you these things exactly, that you may know the effect wrought upon you on that evening of your baptism.
