VATICAN CITY: A decree on training for Roman Catholic priests published on Wednesday stresses the obligation of sexual abstinence, as well as barring gays and those who support “gay culture” from holy orders. “The Church, while deeply respecting the people concerned, cannot admit to a seminary or into holy orders those who practice homosexuality, show deep-seated homosexual tendencies or support what is called gay culture,” said the document. The new comprehensive guide to the training of Catholic clergy, which runs to about 100 pages, was approved by Pope Francis and published by the Osservatore Romano, the Vatican’s official journal. It updates a previous version dating back 30 years. But the barring of people who present homosexual tendencies was already stipulated by the Catholic Church in 2005.
