���The most astonishing thing was that there were actually saints there, even ones who were beatified, who were passing through Purgatory. St. Severinus, Archbishop of Cologne, appeared to one of his friends a long time after his death and told him that he had been in Purgatory for having deferred to the evening the prayers he should have said in the morning. Oh! What years of Purgatory will there be for those Christians who have no difficulty at all in deferring their prayers to another time on the excuse of having to do some pressing work! If we really desired the happiness of possessing God, we should avoid the little faults as well as the big ones, since separation from God is so frightful a torment to all these poor souls!
