One of the nation's best known priests is now caught up in a shocking scandal.
Father Williams appeared frequently as a commentator on both CBS and NBC, often broadcasting live from the Vatican.
He was also the author of Knowing Right From Wrong: A Christian Guide to Conscience.
Now he's confessing that he had a relationship with a woman and fathered a child "a number of years ago."
He apologized in a statement "for this grave transgression," saying, "I am truly sorry to everyone who is hurt by this revelation, and I ask for your prayers as I seek guidance on how to make up for my errors."
Father Williams has taken a year off to "reflect," and is reportedly staying with his parents in Michigan.
His religious order, the Legion Of Christ, says it's sorry it didn't act "earlier and more firmly" to remove him as the television priest.
