One of the first signs of a saint may well be the fact that other people do not know what to make of him. In fact, they are not sure whether he is crazy or only proud; but it must at least be pride to be haunted by some individual ideal which nobody but God really comprehends. And he has inescapable difficulties in applying all the abstract norms of ‘perfection’ to his own life. He cannot seem to make his life fit in with the books.
Sometimes his case is so bad that no monastery will keep him. He has to be dismissed, sent back to the world like Benedict Joseph Labre, who wanted to be a Trappist and a Carthusian and succeeded in neither. He finally ended up as a tramp. He died in some street in Rome.
And yet the only canonized saint, venerated by the whole Church, who has lived either as a Cistercian or a Carthusian since the Middle Ages is St. Benedict Joseph Labre. (New Seeds, 103)
