214 The most fundamental modern error is that of imagining that man's natural sense of religion is nothing more than the outcome of feeling or fantasy, to be eradicated from his soul as an anachronism and an obstacle to human progress. And yet this very need for religion reveals a man for what he is: a being created by God and tending always toward God. As we read in St. Augustine: "Lord, you have made us for yourself, and our hearts can find no rest until they rest in you". (46)
