Katie Holmes “has always been more of a Catholic than a Scientologist,” a source tells PEOPLE, and the desire to make decisions on education and religion for 6-year-old Suri may have influenced her move for sole legal custody.
Other sources maintain that Scientology is not an issue in the split. Tom Cruise, who has not yet answered Holmes’s divorce filing, is a longtime Scientologist and advocate for the sometimes-controversial church, and his older children, Bella, 19, and Connor, 17, were raised in Scientology.
So what is life like for a child being raised in the church – and what would be next for Suri if Scientology stays part of her life?
The influence starts early: Scientologists encourage a pregnant woman to have a “quiet birth” to prevent unwanted emotions and irrational fears from being recorded in a child’s subconscious mind. Cruise told GQ in 2006, “It’s really about respecting the woman. You want to keep things as calm as possible.”
