Rome's opulence, her political machinations down through the centuries, her tyrannies and hauteur and self-assertiveness, not to mention the Dionysian romp in the Vatican in the Renaissance, what with Borgia popes and catamites and so forth: all of that is bad -- very bad. The Catholic Church knows that. Dante, of course, had half of the popes head down in fiery pits in hell.
Chaucer, contemporary with the Lollard Wyclif, but himself a loyal Catholic, is merciless -- scathing even -- in his portraiture of filthy and cynical clergy. St. Thomas More and Erasmus, contemporary with Luther and Calvin, were at least as vitriolic in their condemnation of Roman evils as were the Reformers . . . [But] Israel was not less Israel when she was being wicked . . . The Church is in the same position in its identity as people of God. We have Judas Iscariot, as it were, and Ananias and Sapphira, and other unsavory types amongst us, but we have no warrant to set up shop outside the camp, so to speak . . .
Evangelicals, in their just horror at rampant evils in Catholic history, . . . unwittingly place themselves somewhat with the Donatists of the fourth century, who wanted to hive off because of certain evils which they felt were widespread in the Church. Augustine and others held the view that you can't go that far. You can't set up shop independently of the lineage of bishops . . .
As far as the ancient, orthodox Church was concerned, nobody could split off . . . The problems of the Roman Catholic Church (sin, worldliness, ignorance) are, precisely, the problems of the Church. St. Paul never got out of Corinth before he had all of the above problems. Multiply that small company of Christians by 2000 years and hundreds of millions, and you have what the Catholic Church has to cope with. Furthermore, remember that the poor Catholics aren't the only ones who have to cope.
Anyone who has ever tried to start himself a church has run slap into it all, with a vengeance . . . Worldliness, second-generation apathy, ossification, infidelity, loss of vision, loss of zeal, loss of discipline, jiggery-pokery, heresy -- it's all there.
