In my unloveliness I plunged into the lovely things which you created. You were with me, but I was not with you. Created things kept me from you; yet if they had not been in you, they would have not been at all.
Saint AugustineGod suffers not the pain of repentance, nor is He deceived in any matter, so that He would wish to correct that wherein He has erred. But as when a man repents of anything, he wishes to change what he has done; thus where you hear that God repents, look for an actual change. God does it differently from you, although He calls it by the name of repentance; for thou dost it, because you had erred; while He does it, because He avenges, or frees.
Saint AugustineSo you see how endlessly futile and fruitless it would be if we wanted to refute their objections every time they obstinately resolved not to think through what they say but merely to speak, just so long as they contradict our arguments in any way they can.
Saint AugustineAlthough among heretics and schismatics there is the same Baptism, nevertheless, the remission of sins is not operative among them because of the very rottenness of discord and wickedness of dissension ... Baptism was in them, but it did not profit them outside the Church ... Outside the Church, Baptism works death because of discord.
