The (Communism of) the Reign of God

From Sigrid Undset, St Catherine of Siena: "This is the communism of the society of the blessed: just as the rewards of the blessed are collected in the treasure-houses of the Church, so that every poor and infirm soul may have a share of this treasure, so in a mysterious way the sins of the faithful impoverish the whole of Christendom. Our generation, which has seen how the horrors of war and the concentration camps have fallen alike on the guilty and on those who by human reckoning were the most guiltless, should find it easier than our forefathers, with their naive believe in personal success as a reward for personal service, to understand the dogma of the Church that we all have our share in the rewards of all the saints and the guilt of all sinners."
