The Archbishop of Naples now commissioned him to reform a convent at Naples, which by the laxity of its discipline had become a source of great scandal. By his own example and his untiring zeal he restored the religious discipline of the convent but not without many and great difficulties. Certain wicked men who were accustomed to have clandestine meetings with the nuns became exasperated at the saint's interference, and one night he was assaulted and severely wounded. He was brought to the monastery of the Theatines to recuperate. Here, however, he resolved to devote himself entirely to God and he entered the Order of Theatines, which had only recently been founded by St. Cajetan. In 1556, on the vigil of the Assumption he was invested, being then thirty-five years of age. He took the name of Andrew in honor of the apostle.
