João 20:17
For Christ's purpose in the incarnation was to pave for us the road to heaven. Mark how he says, "I go up to my Father and your Father, to my God and your God." — Exposition of the Christian Faith 3.7.50
João 20:23
They affirm that they are showing great reverence for God, to whom alone they reserve the power of forgiving sins. But in truth no one does him greater injury than those who choose to prune his commandments and reject the office entrusted to them. For the Lord Jesus himself said in the Gospel, "Receive the Holy Spirit; whoever's sins you forgive they are forgiven to them, and whoever's sins you retain, they are retained." Who is it that honors him most, the one who obeys his bidding or the one who rejects it?The church holds fast its obedience on either side by both retaining and remitting sin. Heresy is on the one side cruel and on the other disobedient. It wishes to bind what it will not loosen and will not loosen what it has bound, whereby it condemns itself by its own sentence. For the Lord willed that the power of binding and of loosing should be the same, and he sanctioned each by a similar condition. So whoever does not have the power to loose does not have the power to bind. For as, according to the Lord's word, the one who has the power to bind also has the power to loose, their teaching destroys itself, inasmuch as those who deny that they have the power of loosing ought also to deny that of binding. For how can the one be allowed and the other disallowed? It is plain and evident that either each is allowed or each is disallowed in the case of those to whom each has been given. Each is allowed to the church; neither is allowed to heresy. For this power has been entrusted to priests alone. It is only right, therefore, that the church, which has true priests, claims it. Heresy, which does not have the priests of God, cannot claim it. And by not claiming this power heresy pronounces its own sentence, that not possessing priests it cannot claim priestly power. — Concerning Repentance 1.2.6-7
João 20:28
You have read that the Father is both Lord and God: "O Lord my God, I will call on you, hear me." You find the Son to be both Lord and God, as you have read in the Gospel, that, when Thomas had touched the side of Christ, he said, "My Lord and my God." So just as the Father is God and the Son Lord, so too the Son is God and the Father Lord. The holy designation changes from one to the other. The divine nature does not change, but the dignity remains unchangeable. For they are not [as it were] contributions gathered from bounty but free-will gifts of natural love. For unity has its special property, and the special properties are bound together in unity. — On the Holy Spirit 3.15.108
João 20:29
There are some … who think a blessed life is impossible in this body, weak and fragile as it is. For we have to suffer pain and grief, weeping, illness—all in this body.… It is not a blessing to be in the midst of suffering. But it is a blessing to be victorious over it and not to be bullied by the power of temporal pain. Suppose that things come that are considered terrible because of the grief they cause, such as blindness, exile, hunger, violation of a daughter, loss of children. Who will deny that Isaac was blessed, who did not see in his old age, and yet gave blessings with his benediction? Was not Jacob blessed who, leaving his father's house, endured exile as a shepherd for pay, and mourned for the violated chastity of his daughter and suffered hunger? Were they not blessed on whose good faith God received witness, as it is written: "The God of Abraham, the God of Isaac and the God of Jacob"? A wretched thing is slavery, but Joseph was not wretched. In fact, clearly he was blessed when, while a slave, he checked the lusts of his mistress. What shall I say of holy David, who bewailed the death of three sons, and, what was even worse than this, his daughter's incestuous connection? How could he be unblessed from whom the author of blessedness himself sprung who has made many blessed? For "blessed are they who have not seen yet have believed." All these felt their own weakness, but they bravely prevailed over it. What can we think of as more wretched than holy Job, either in the burning of his house, or the instantaneous death of his ten sons or his bodily pains? Was he less blessed than if he had not endured those things whereby he really showed himself approved?It is true that in these sufferings there is something bitter and that we cannot use mind over matter to hide this pain. I should not deny that the sea is deep because in shore it is shallow, or that the sky is clear because sometimes it is covered with clouds, or that the earth is fruitful because in some places there is only barren ground or that the crops are rich and full because they sometimes have wild oats mingled with them. So, too, count it as true that the harvest of a happy conscience may be mingled with some bitter feelings of grief. In the sheaves of the whole of a blessed life, if by chance any misfortune or bitterness has crept in, is it not as though the wild oats were hidden or as though the bitterness of the tares was concealed by the sweet scent of the corn? — On the Duties of the Clergy 2.5.19-21
