We need permanent conversion

Initially, Augustine thought that once he was baptized, in the life of communion with Christ, in the sacraments, in the Eucharistic celebration, he would attain the life proposed in the Sermon on the Mount: the perfection bestowed by Baptism and reconfirmed in the Eucharist. During the last part of his life he understood that what he had concluded at the beginning about the Sermon on the Mount - that is, now that we are Christians, we live this ideal permanently - was mistaken. Only Christ himself truly and completely accomplishes the Sermon on the Mount. We always need to be washed by Christ, who washes our feet, and be renewed by him. We need permanent conversion. Until the end we need this humility that recognizes that we are sinners journeying along, until the Lord gives us his hand definitively and introduces us into eternal life. It was in this final attitude of humility, lived day after day, that Augustine died.

This attitude of profound humility before the only Lord Jesus led him also to experience an intellectual humility. Augustine, in fact, who is one of the great figures in the history of thought, in the last years of his life wanted to submit all his numerous works to a clear, critical examination. This was the origin of the Retractationum ("Revision"), which placed his truly great theological thought within the humble and holy faith that he simply refers to by the name Catholic, that is, of the Church. He wrote in this truly original book: "I understood that only One is truly perfect, and that the words of the Sermon on the Mount are completely realized in only One - in Jesus Christ himself. The whole Church, instead - all of us, including the Apostles -, must pray everyday: Forgive us our sins as we forgive those who sin against us" (De Sermone Domini in Monte, I, 19, 1-3).
