We want to commend to St. Augustine a further meditation on our psalm. In it, the Father of the Church introduces a surprising element of great timeliness: He knows that also among the inhabitants of Babylon there are people who are committed to peace and the good of the community, despite the fact that they do not share the biblical faith, that they do not know the hope of the Eternal City to which we aspire. They have a spark of desire for the unknown, for the greatest, for the transcendent, for a genuine redemption.

And he says that among the persecutors, among the nonbelievers, there are people with this spark, with a kind of faith, of hope, in the measure that is possible for them in the circumstances in which they live. With this faith in an unknown reality, they are really on the way to the authentic Jerusalem, to Christ. And with this opening of hope, valid also for the Babylonians -- as Augustine calls them -- for those who do not know Christ, and not even God, and who nevertheless desire the unknown, the eternal, he exhorts us not to look only at the material things of the present moment, but to persevere in the path to God. Only with this greater hope can we transform this world in a just way.
