Pope Francis on Saturday accepted the resignation of Cardinal Theodore McCarrick, one of the U.S. Catholic Church's most prominent figures, who has been at the centre of a widening sexual abuse scandal.

McCarrick, 88, the former archbishop of Washington, D.C., is the first cardinal in living memory to lose his red hat and title. Other Cardinals, who have been disciplined in sexual abuse scandals, kept their membership in the College of Cardinals and their honorific "your eminence".

The allegations against McCarrick, which first surfaced publicly last month, came with Francis facing an image crisis on a second front, in Chile, where a growing abuse scandal has enveloped the Church.

A Vatican statement said the pope, acting only hours after McCarrick offered his resignation on Friday night, ordered his suspension from the exercise of any public ministry. This means he remains a priest but will be allowed to say Mass only in private.

Francis also ordered McCarrick to go into seclusion "for a life of prayer and penance until the accusations made against him are examined in a regular canonical trial". The Vatican said the pope wanted to send a strong message that high rank would no longer be a shield.

McCarrick's sudden fall from grace stunned the American Church because he was a widely respected leader for decades and a confidant of popes and presidents. Last month, American Church officials said allegations that he sexually abused a 16-year-old boy almost 50 years ago were credible and substantiated.

Since then, another minor has come forward with allegations that McCarrick abused him when he was 11 years old, and several men have come forward to allege that McCarrick forced them to sleep with him at a beach house in New Jersey when they were adult seminarians studying for the priesthood.

McCarrick has said that he had "absolutely no recollection" of the alleged abuse of the teenager 50 years ago but has not commented on the other allegations.

The New York Times reported last week that two dioceses in New Jersey, where McCarrick served as bishop before being promoted to Washington in 2000, had reached financial settlements in 2005 and 2007 with men who said they were abused by McCarrick as adults decades ago.

Some U.S. Catholics have said the Vatican should send an inspector to the United States to determine who in the U.S. Church hierarchy knew of the alleged incidents and why McCarrick's rise was not impeded.

The last person to resign from the College of Cardinals is believed to be French theologian Louis Billot, who left over a disagreement with Pope Pius XI in 1927, according to the U.S. newspaper, National Catholic Reporter.
