Dilige et quod vis fac. (Love and then what you will, do.) - Augustine of Hippo

We may not assent to the teaching even of the Catholic bishops, if at any time they are deceived into opinions contrary to the canonical Scriptures of God; but if they should so fall into error, and yet maintain the bond of unity and charity, let the apostle's saying avail in their case: 'And if in anything ye are otherwise minded, God shall reveal even this unto you.' Now these divine words have so manifest an application to the whole Church, that none but heretics in their stubborn perverseness and blind fury can bark against them. (Cf. Augustine's Reply to Faustus the Manichaean (Contra Faustum), book 11, 5 )

I count myself one of the number of those who write as they learn and learn as they write.” Augustine/John Calvin

What did it profit that I read the greatest human ideas of the so-called “liberal arts” in the books I got hold of. My thinking was enslaved to corrupt desires, so what difference did it make that I could read and understand these books? I delighted in learning, but I had no divine context for what my mind picked up. I had no foundation to discern what is true or certain. I was standing with my back to the light, so that the things that should be illuminated were in shadow, even though they were in front of my face.
