It has been claimed that Catherine, a century and a half later, would have been a Protestant. Such hypotheses are always futile to discuss; but the view hardly commends itself to the careful student of her writings. It is suggested, naturally enough, by her denunciations of the corruptions of the Church, denunciations as sweeping and penetrating as were ever uttered by Luther; by her amazingly sharp and outspoken criticism of the popes; and by her constant plea for reform. The pungency of all these elements in her writings is felt by the most casual reader. But it must never be forgotten that honest and vigorous criticism of the Church Visible is, in the mind of the Catholic philosopher, entirely consistent with loyalty to the sacerdotal theory. There is a noble idealism that breaks in fine impatience with tradition, and audaciously seeks new symbols wherein to suggest for a season the eternal and imageless truth. But perhaps yet nobler in the sight of God--surely more conformed to His methods in nature and history--is that other idealism which patiently bows to the yoke of the actual, and endures the agony of keeping true at once to the heavenly vision and to the imperfect earthly form. Iconoclastic zeal against outworn or corrupt institutions fires our facile enthusiasm. Let us recognize also the spiritual passion that suffers unflinchingly the disparity between the sign and the thing signified, and devotes its energies, not to discarding, but to restoring and purifying that sign. Such passion was Catherine's. The most distinctive trait in the woman's character was her power to cling to an ideal verity with unfaltering faithfulness, even when the whole aspect of life and society around her seemed to give that verity the lie. To imagine her without faith in the visible Church and the God-given authority of the Vicar of Christ is to imagine another woman. Catherine of Siena's place in the history of minds is with Savonarola, not with Luther.
