O'Fallon, Missouri (CNN) -- Nathan Halbach is 22, with a diagnosis of terminal brain cancer. He knows that "horrible stuff" lies ahead. His mother, Pat Bond, has been taking care of him full time. But when she needed help, she reached out to the Roman Catholic Church. After all, his father is a priest. Nathan was born in 1986, during a five-year affair between his mother and Father Henry Willenborg, the Franciscan priest who celebrated Nathan's baptism. In a story first reported in the New York Times, it was revealed that The Franciscan Order drew up an agreement acknowledging the boy's paternity and agreeing to pay child support in exchange for a pledge of confidentiality.
