What is held by the whole Church, and that not as instituted by Councils, but as a matter of invariable custom, is rightly held to have been handed down by authority.

If a shameless woman expects to be defiled and then dies of her fierce love because you do not consent, will chastity also be homicide?

God bestows more consideration on the purity of the intention with which our actions are performed than on the actions themselves.

For God loves saving, not condemning, and therefore He is patient with bad people, in order to make good people out of bad people.

The bread that you see on the altar is the Body of Christ as soon as it is sanctified by God's word. The chalice, or better what is contained in the chalice, is the Blood of Christ as soon as it is sanctified by God's word

I thought that continence was a matter of our own strength, and I knew that I had not the strength: for in my utter foolishness I did not know the word of Your Scripture that none can be continent unless You give it.

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.
