No one knows what he himself is made of, except his own spirit within him, yet there is still some part of him which remains hidden even from his own spirit; but you, Lord, know everything about a human being because you have made him...Let me, then, confess what I know about myself, and confess too what I do not know, because what I know of myself I know only because you shed light on me, and what I do not know I shall remain ignorant about until my darkness becomes like bright noon before your face.
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.
Oh, God, to know you is life. To serve You is freedom. To praise you is the soul's joy and delight. Guard me with the power of Your grace here and in all places. Now and at all times, forever. Amen.
Baptism does not profit a man outside unity with the Church ... For many heretics also possess this Sacrament but not the fruits of salvation ... The benefits which flow from Baptism are necessarily fruits which belong to the true Church alone. Children Baptized in other communions cease to be members of the Church when, after reaching the age of reason, they make formal profession of heresy, as, for example, by receiving communion in a non-Catholic Church.
Let us, on both sides, lay aside all arrogance. Let us not, on either side, claim that we have already discovered the truth. Let us seek it together as something which is known to neither of us. For then only may we seek it, lovingly and tranquilly, if there be no bold presumption that it is already discovered and possessed.
God's faithful servant has no desire for people to say or to give to him, or what he likes to hear or see, for his first and greatest aim is to hear what is most pleasing to God.
Recognize in this bread what hung on the cross, and in this chalice what flowed from His side... whatever was in many and varied ways announced beforehand in the sacrifices of the Old Testament pertains to this one sacrifice which is revealed in the New Testament.
Furthermore, what profit was it to me that I, rascally slave of selfish ambitions that I was, read and understood by myself as many books as I could get concerning the so-called liberal arts?...I had turned my back to the light and my face to the things it illuminated, and so no light played upon my own face, or on the eyes that perceived them.
What is perfection in love? Love your enemies in such a way that you would desire to make them your brothers ... For so did He love, Who hanging on the Cross, said "Father, forgive them, for they know not what they do." (Luke 23:34)
