Patrick Peyton emigrated from Mayo in 1928 meaning to make money in America, and was a sexton in a cathedral in Scranton when he decided to become a priest. In 1938, a student of theology with the Congregation of Holy Cross, he was found to have advanced tuberculosis and was not expected to be ordained. He recovered, held it to be Our Lady's doing, and promised her his priesthood. He was ordained on 15 June 1941.
He then did the one thing he had promised, on a scale nobody expected. The Family Rosary Crusade began in 1942 with letters to bishops, and by the end of the decade he was on network radio: Family Theater, first broadcast in 1946, ran for decades and carried Hollywood actors who worked for nothing. He coined nothing himself — the line was written for him by an advertising man — but he said it until the English-speaking world knew it: <em>the family that prays together stays together.</em>
The crusade took him around the world, and the rallies were enormous: crowds counted in the hundreds of thousands and, in Manila and São Paulo, in the millions. He died on 3 June 1992 at San Pedro in California, holding a rosary, and was declared Venerable on 18 December 2017. The site's Rosary section exists in a world he shaped; he is the reason a great many families still say it at all.
