Putative Pope Francis said the following:
From the National Catholic Reporter. (Some may argue that since the Reporter is heretical, they must surely have twisted Bergoglio's words, and he has never said anything but pure Catholic truth. To that I can only say, after I stop grimly laughing, he's said the same sort of thing tons of times, reported by many sources of varying agenda and levels of orthodoxy.)"There is a big sin against ecumenism: proselytism," said the pontiff. "You must never proselytize the Orthodox. They are our brothers and sisters, disciples of Jesus Christ."
So trying to convert those in the Eastern schism is a sin. Hmm. He should try telling that to St. Josaphat Kuncevyc, bishop and martyr.
From his zealous study of the liturgical books he drew many proofs of Catholic truth, using his knowledge in the composition of several works — "On the Baptism of St. Volodymyr"; "On the Falsification of the Slavic Books by the Enemies of the Metropolitan"; "On Monks and their Vows". As deacon, priest, and bishop, he was distinguished by his extraordinary zeal in the service of souls. Not alone in the church did he preach and hear confessions, but likewise in the fields, hospitals, prisons, and even on his journeys. Even where his words of instruction might by themselves have failed, his entreaties and tears ensured him success. This zeal, united with his kindness and extraordinary love for the poor, won numbers to the Catholic Faith. Among his converts were included many important personages such as Ignatius, Patriarch of Moscow, and Emmanuel Cantacuzenus, who belonged to the family of the Greek Emperor Palæologus.
As archbishop he restored the churches; issued a catechism to the clergy with instructions that it should be learned by heart; composed rules for the priestly life, entrusting to the deacons the task of superintending their observance; assembled synods in various towns in the dioceses, and firmly opposed the Imperial Chancellor Sapieha, when he wished to make many concessions in favour of the schismatics. Throughout all his strivings and all his occupations, he continued his exemplary life as a religious, and never abated his zeal for self-mortification and prayer.
From the Catholic Encyclopedia, published in 1910, accessed at New Advent.While each succeeding year saw fresh evidence of his fruitful labours, it also witnessed the steady growth of the hatred of the schismatic party. Finally on 12 November, 1623, an axe-stroke and a bullet brought Josaphat his martyr's crown. After numerous miracles had occurred, a commission was appointed by Urban VIII in 1628 to inquire into the cause of Josaphat, and examined on oath 116 witnesses. Although five years had elapsed since Josaphat's death, his body was still incorrupt. In 1637 a second commission investigated the life of the martyr, and in 1643 — twenty years after his death — Josaphat was beatified. His canonization took place in 1867.
