More quotes from our wonderful Church Fathers in defence of the True Faith:
Saint Theophilus of Antioch (died A.D. 181): âAnd as, again, there are other islands, rocky and without water, and barren, and infested by wild beasts, and uninhabitable, and serving only to injure navigators and the storm-tossed, on which ships are wrecked, and those driven among them perish, - so there are doctrines of error - I mean heresies - which destroy those who approach them. For they are not guided by the word of truth; but as pirates, when they have filled their vessels, drive them on the fore-mentioned places, that they may spoil them: so also it happens in the case of those who err from the truth, that they are all totally ruined by their error.â (To Autolyctus)
Saint Irenaeus (died A.D. 202): "Since therefore we have such proofs, it is not necessary to seek the truth among others [heretics] which it is easy to obtain from the Church; since the apostles, like a rich man [depositing his money in a bank,] lodged in her hands most copiously all things pertaining to the truth: so that every man, whosoever will, can draw from her the water of life. For she is the entrance to life; all others are thiefs and robbers. On this account we are bound to avoid them, but to make choice of the things pertaining to the Church with the utmost diligence, and to lay hold of the tradition of the truth.
Origen (died A.D. 254): âLet no man deceive himself. Outside this house, that is, outside the Church no one is saved.â (In Iesu Nave homiliae)
