Because of the large sums of money he expended, Peter became penniless. He was without resources and powerless when the Blessed Virgin appeared and said to him: “Find for Me other men like yourself, an army of brave, generous, unselfish men, and send them into the lands where the children of the Faith are suffering.” Peter went at once to Saint Raymond of Pennafort, his confessor, who had had a similar revelation and used his influence with King James I of Aragon and with Berengarius, Archbishop of Barcelona, to obtain approbation and support for the new community. On August 10, 1218, Peter and two companions were received as the first members of the Order of Our Lady of Ransom, dedicated to the recovery of Christian captives. To the three traditional vows of religion, its members joined a fourth, that of delivering their own persons to the overlords, if necessary, to ransom Christians.
The Order spread rapidly. Peter and his comrades traveled throughout Christian Spain, recruiting new members and collecting funds to purchase the captives. Then they began negotiations with the slave-owners. They penetrated Andalusia, crossed the sea to Tunis and Morocco, and brought home cargo after cargo of Christians. Although Peter, as General of the Order, was occupied with its organization and administration, he made two trips to Africa where, besides liberating captives, he converted many Muslims. He died after a long illness on Christmas night of 1256; he was canonized by Pope Urban VIII in 1628. His Order continues its religious services, now devoted to preaching and hospital service.
