Katie Holmes felt she had to end her five-year marriage to Tom Cruise because she was concerned he would send their six-year-old daughter Suri to a floating Scientology camp.
The former 'Dawson's Creek' star filed for divorce from the 'Rock Of Ages' actor - who is a devotee to the religious cult - after five years of marriage last week, and her worry he wanted to place their six-year-old daughter Suri with the Sea Organisation, a floating school, was reportedly behind her move.
Those on board the ship are required to commit themselves to the quasi-religious sect for a billion years and allegedly asked to disconnect from any non-believers.
A source told TMZ.com: ''In the end we're told Katie felt the only way to prevent Suri from joining the Sea Org ship was to file for divorce and seek sole legal custody.''
However, a lawyer representing The Cult has claimed no one under 16 is allowed to join the cruise liner, adding ''consent of both parents and/or all legal guardians'' must be given before anyone is allowed to board.
Despite Katie's fears, it is believed Tom will ''move heaven and earth'' to ensure his daughter is brought up a Scientologist.
A source said: ''Tom believes Scientology changes people's lives for the better and, obviously, he wants what is best for his children.
''Tom will move heaven and earth to ensure Suri stays a Scientologist, at least until she is of an age to make a decision to leave on her own accord.''
