Accordingly, eat the bread of heaven in a spiritual way. Come to it freed from sin. Even though your sins occur daily, at least see to it that they be not mortal.
Moreover, before you approach the altar note well what you say: "Forgive us our trespasses as we forgive those who trespass against us." If you forgive others, God will forgive you.
-- Sermon on John 26, 11
Prayer. Forgive us, Lord, all these things in which we have been led astray. Help us to resist being led away.
-- Punishment and the Forgiveness of Sins 2, 4
