Saint Irenaeus... Against Heresies, 3:4:1, Jurgens 213,
"This Church is holy, the one Church, the true Church, the Catholic Church, fighting as she does against all heresies. She can fight, but she cannot be beaten. All heresies are expelled from her, like the useless loppings pruned from a vine. She remains fixed in her root, in her vine, in her love. The gates of hell shall not conquer her."
Saint Augustine of Hippo... Sermon to Catechumens, on the
Jurgens 1535, 395 A.D.
"If you want GOD to forgive, you must confess. Sin cannot go unpunished. It were seemingly, improper, and unjust for sin to go unpunished. Since, therefore, sin must not go unpunished, let it be punished by you, lest you be punished for it. Let your sin have you for its judge, not its patron. Go
up and take the bench against yourself, and put the guilt before yourself.
Do not put it behind you, or GOD will put it in front of you."
Saint Augustine of Hippo... Sermons, 20:2, J1494, 410 A.D.
"We must understand that the divine operation, if comprehended by reason, is not remarkable; nor does that faith which human reason puts to the test have merit... The body of the Lord came into the presence of the disciples through closed doors, which body, in truth, at His birth came forth to
human eyes from the closed womb of the Virgin. What wonder then, if after His Resurrection and about to reign victorious in eternity, He entered through closed doors, who, coming so that He might die, came forth from the unopened womb of the Virgin?"
Saint Gregory I... Homilies on the Gospels, 2:26:1, J2331, 590 A.D.
"Nothing under the sun is new, neither is any man able to say:
Behold this is new; for it has already gone before in the ages that were before us."
