Katie Holmes: From Catholicism to Scientology

Before Katie Holmes got the role that propelled her to stardom—as Joey Potter on "Dawson's Creek"—she was just your average small-town, church-going girl. Thus far she's managed a somewhat successful movie and stage career, but currently her most famous role is as Tom Cruise's wife. Baptized and raised a Roman Catholic, within weeks of dating Cruise—who's been an outspoken Scientologist since 1990—Holmes was taking Scientology classes. In 2006 they were married in a Scientology ceremony, after the given birth of their daughter Suri earlier that year (Katie had a "silent birth" in accordance with Scientology practices). While a rep for the Church of Scientology claims that one needs not renounce his or her former faith to join, Cruise told Diane Sawyer in a 2006 interview, "You can be Catholic and be a Scientologist. You can be Jewish and be a Scientologist. But we’re just Scientologists."
