The Vatican said on Friday it had disciplined the ageing Mexican founder of an influential Catholic religious order who has been accused of sexual abuse, instructing him to retire to a life of "prayer and penitence".
The censure of Father Marcial Maciel, 86-year-old founder of the Legionaries of Christ, is significant because he and his conservative order had found favour under the late Pope John Paul, making the decision by Pope Benedict even bolder.
The instruction was the new Pope's first major decision involving sexual abuse charges since his election last year. Before he was elected, Benedict decried the "filth" in the Church.
The sanctions against Maciel made him one of the most prominent persons to be disciplined for alleged sexual abuse and could be devastating for the priestly order and its lay branch, Regnum Christi, which claims tens of thousands of members.
Founded by Maciel in 1941, the order now has about 600 priests and 2,500 seminarians in more than 20 countries. It also runs a major Pontifical university in Rome.
Maciel, who lives in Mexico, has been accused by some former seminarians of sexual abuses dating back to the 1940s and 1950s, when they were boys as young as 10.
