"...Christianity is not a creed for good men, but for men..."

Now it is true that the Church, by the Renascence period, had reached a considerable corruption; but the real proofs of it are utterly different both from the contemporary despotic pretence and from the common Protestant story. It is wildly unfair, for instance, to quote the letters of bishops and such authorities denouncing the sins of monastic life, violent as they often are. They cannot possibly be more violent than the letters of St. Paul to the purest and most primitive churches; the apostle was there writing to those Early Christians whom all churches idealize; and he talks to them as to cut-throats and thieves. The explanation, for those concerned for such subtleties, may possibly be found in the fact that Christianity is not a creed for good men, but for men. Such letters had been written in all centuries; and even in the sixteenth century they do not prove so much that there were bad abbots as that there were good bishops. Moreover, even those who profess that the monks were profligates dare not profess that they were oppressors; there is truth in Cobbert's point that where monks were landlords, they did not become rack-renting landlords, and could not become absentee landlords. Nevertheless, there was a weakness in the good institutions as well as a mere strength in the bad ones; and that weakness partakes of the worst element of the time. In the fall of good things there is almost always a touch of betrayal from within; and the abbots were destroyed more easily because they did not stand together. They did not stand together because the spirit of the age (which is very often the worst enemy of the age) was the increasing division between rich and poor; and it had partly divided even the rich and poor clergy. And the betrayal came, as it nearly always comes, from that servant of Christ who holds the bag.
