Again, it seems so from reason, for everyone having grace and justice enters into the kingdom of heaven, nor can anyone close the gate, justice and grace being preserved; but no one can enter into the kingdom of heaven except through the doorward [ostiarium] Peter, since the keys are given to him, from which no one is exempt: therefore no one can obtain grace nor have remission of guilt, unless he has it through the authority of the supreme Pontiff and those who are in communion with him. But no one is absolved by a priest without confession first, ergo etc . . . it should be replied that to enter without the power of the keys can be understood in two ways: either without the power, understood contrarily, as though despising the key of Peter; or without the power, understood privatively, and this [can be understood] in two ways: either simply privatively, so that one does not have the effect of absolution, neither in work nor in devotion nor in desire; or so that one has it in devotion and intention [proposito], and so has it in a certain way. In the first and second way one does not enter, nor is justified, but in the third way one may enter, and this in some way through the key, although not just as he who is actually absolved.
And the second:
God is more prone to being merciful than to condemning . . . God does not restrict his power to the sacraments. Therefore whenever man does what is in himself, God does what is in himself: therefore, if someone is sorry for his guilt in his heart, [even] if there is not a confessor or external confession, God does what is in himself: therefore he justifies.
