Such then in number and importance are the precious ties belonging to the Christian name which keep a believer in the Catholic Church, as it is right they should ... With you, where there is none of these things to attract or keep me... No one shall move me from the faith which binds my mind with ties so many and so strong to the Christian religion... For my part, I should not believe the gospel except as moved by the authority of the Catholic Church.
You (God) have not only commanded continence, that is, from what things we are to restrain our love, but also justice, that is, on what we are to bestow our love.
Passion is the evil in adultery. If a man has no opportunity of living with another man's wife, but if it is obvious for some reason that he would like to do so, and would do so if he could, he is no less guilty than if he was caught in the act.
People travel to wonder at the height of mountains, at the huge waves of the sea, at the long courses of rivers, at the vast compass of the ocean, at the circular motion of the stars; and they pass by themselves without wondering.
Therefore once for all this short command is given to you. 'Love and do what you will.' If you keep silent, keep silent by love; if you speak, speak by love; if you correct, correct by love; if you pardon, pardon by love: let love be rooted in you, and from the root nothing but good can grow.

Divine Scripture is wont to frame, as it were, allurements for children from the things which are found in the creature; whereby, according to their measure, and as it were by steps, the affections of the weak may be moved to seek those things that are above, and to leave those things that are below. But the same Scripture rarely employs those things which are spoken properly of God, and are not found in any creature; as, for instance, that which was said to Moses, I am that I am; and, I Am has sent me to you."
Whoever seems to himself to have understood the Scriptures in such a way that he does not build up that double love of God and neighbor has not yet understood.
Everyone who observes himself doubting observes a truth, and about that which he observes he is certain; therefore he is certain about a truth. Everyone therefore who doubts whether truth exists has in himself a truth on which not to doubt.... Hence one who can doubt at all ought not to doubt the existence of truth.
If you would attain to what you are not yet, you must always be displeased by what you are. For where you are pleased with yourself there you have remained. Keep adding, keep walking, keep advancing.
