"The virtue of faith, the foundation of a Christian life, gives us an absolute certitude of the truths which we believe; a certitude more positive than that which is based on the testimony of our eyes and reason. It rests on God, whose word cannot fail: and on the Church, which is likewise infallible when teaching us that word."
