Catherine's letters on public affairs--historical documents of recognised importance--give us her practical programme. It was formed in the light of that faith which she always describes as "the eye of the mind." She was called during her brief years of political activity to meet three chief issues: the absence of the Pope from Italy; the rebellion of the Tuscan cities, headed by Florence, against his authority; and at a later time the great Schism, which broke forth under Urban VI. During her last five years she was absorbed in ecclesiastical affairs. In certain of her immediate aims she succeeded, in others she failed. It would be hard to say whether her success or her failure involved the greater tragedy. For behind all these aims was a larger ideal that was not to be realised--the dream, entertained as passionately by Catherine Benincasa as by Savonarola or by Luther, of thorough Church-reform. Catherine at Avignon, pleading this great cause in the frivolous culture and dainty pomp of the place; Catherine at Rome, defending to her last breath the legal rights of a Pope whom she could hardly have honoured, and whose claims she saw defended by extremely doubtful means--is a figure as pathetic as heroic. Few sorrows are keener than to work with all one's energies to attain a visible end for the sake of a spiritual result, and, attaining that end, to find the result as far as ever. This sorrow was Catherine's. The external successes which she won--considerable enough to secure her a place in history-- availed nothing to forward the greater aim for which she worked. Gregory XI., under her magnetic inspiration, gathered strength, indeed, to make a personal sacrifice and to return to Rome, but he was of no calibre to attempt radical reform, and his residence in Italy did nothing to right the crying abuses that were breaking Christian hearts. His successor, on the other hand, did really initiate the reform of the clergy, but so drastic and unwise were his methods that the result was terrible and disconcerting--the development of a situation of which only the Catholic idealist could discern the full irony; no less than Schism, the rending of the Seamless Robe of Christ.
