VATICAN CITY (AP) — Thomas Williams, the onetime public face of the disgraced Legion of Christ religious order who left the priesthood after admitting he fathered a child, is getting married this weekend to the child's mother, The Associated Press has learned. The bride is the daughter of former U.S. Ambassador to the Holy See Mary Ann Glendon, one of Pope Francis' top advisers.

Glendon, a Harvard University law professor, is one of the highest-ranking women at the Vatican as president of the Pontifical Academy for Social Sciences. She is also one of five people on Francis' commission to reform the scandal-marred Vatican bank. Her daughter, Elizabeth Lev, is a Rome-based art historian and columnist for the Legion-run Zenit news agency, which Williams published for over a decade while he was in the order.

Williams, a moral theologian, author, lecturer and U.S. television personality, admitted last year that he had fathered a child several years earlier.

At the time, Williams apologized for "this grave transgression" against his vows of celibacy and said he had stayed on as a priest because he hoped to move beyond "this sin in my past" to do good work for the church. The Legion's retired superior later admitted he had learned about the child in 2005 but allowed Williams to keep teaching and preaching about morality.

After taking a year off for reflection, Williams left the priesthood in May to care for his son. According to their wedding registry, he and Lev are due to marry on Saturday in the United States.

Asked for comment Thursday, Lev confirmed the wedding plans in an email, adding: "We have no intention of ever discussing our personal life in this forum."

She had initially denied an intimate relationship with Williams, though they frequently appeared together in American circles in Rome, particularly with visiting U.S. student and Catholic tour groups.

Their wedding closes a circle of sorts, even as it raises some uncomfortable questions: Who beyond Williams' superior in the church knew about the child while the couple tried to cover it up? Was Williams already in a relationship with Lev when she became a regular contributor to the magazine he published? And did the family ties to Williams influence Glendon in her defense of the Legion and its disgraced founder despite credible reports that the founder was a pedophile?

The questions swirled Thursday as the Legion dropped a bombshell of its own, admitting that a superior who was in charge of the bulk of its American priests-in-training for over a decade sexually abused a minor at the Legion's novitiate in Cheshire, Connecticut. The Legion said a second accuser had also come forward with an allegation against the Rev. William Izquierdo, who was novice director at the Cheshire school from 1982-1994 and in Ireland before then. Izquierdo, now 85, has dementia.

The saga of the Legion of Christ represents one of the most egregious examples of how the Vatican ignored decades of reports about sexually abusive priests as church leaders put the interests of the institution above those of the victims.

The Rev. Marcial Maciel founded the cult-like Legion in 1941 in Mexico and oversaw its growth into a large and prominent congregation despite credible reports that he was a drug addict and child molester. After Maciel's death in 2008, the Legion admitted that he fathered three children and sexually abused his seminarians.

In 2010, the Vatican took over the order and a papal delegate has been overseeing a reform and "purification." In January, the Legion will elect a new leadership and approve a new set of constitutions.

The Legion scandal has been particularly damaging to the Vatican because Maciel was held up by Pope John Paul II and his cardinals as a model for the faithful, with the order admired for its orthodoxy and ability to bring in money and new priests.

Like all Legion priests, Williams had been a staunch defender of Maciel. When Maciel's double life became public in 2009, Williams told the Catholic ETWN program that the revelations were a "very, very hard blow to all of us."

Until he left active ministry, Williams was the most publicly prominent priest in the 950-strong order. He is the author of such books as 2008's "Knowing Right From Wrong: A Christian Guide to Conscience," and was a commentator for the U.S. broadcaster CBS. He was the superior of the Legion's general directorate in Rome in the late 1990s and early 2000s.

The Legion's revelation about a senior cleric having abused a novitiate was contained in a report on the steps the Legion has taken to address sexually abusive clergy within its ranks and respond to the victims of Maciel. According to the report by the Legion's superior, the Rev. Sylvester Heerman, 35 priests have been accused of sexually abusing minors; nine were found guilty and 14 were acquitted in a church trial. Two had left the priesthood when the allegations were made, so no church sanctions could be imposed, and 10 cases are still under review. In addition, two Legion superiors were found guilty of sexually abusing adults under their case and three were acquitted.

The Legion said the numbers indicate that less than 1 percent of the 1,133 priests ordained in the 72-year history of the order had been found guilty by a church trial of abuse, and less than 4 percent had been accused. A Legion spokesman said he didn't know what the percentage was for the current number of Legion priests.

CORRECTION: In a story Dec. 5 about the wedding of a former Legion of Christ priest, The Associated Press reported erroneously that the Legion said less than 4 percent of Legion priests had been abused. Less than 4 percent have been accused of sexual abuse, according to the Legion.

    Visitors stand inside a church made entirely of snow and ice in southern Bavaria on January 14, 2012 in Mitterfirmiansreut, Germany. Local enthusiasts built the church at the end of December in an effort to relive a tradition dating back over 100 years. In 1910 the residents of Mitterfirminsreut were cut off from their local parish by a heavy snowstorm, and since the village was without its own church, they were unable to attend Christmas mass. Then in January of 1911, in an act meant in protest against local authorities whom they felt had forgotten them, the residents built their own church out of the material they had most in abundance at the time: snow. This year the snow church, backed by a local association, is scheduled to stand through February and has quickly become a local tourist attraction. (Photo by Johannes Simon/Getty Images)
