Tom Cruise doesn't believe Katie Holmes filed for divorce because of Scientology.
The former 'Dawson's Creek' actress submitted papers to end their five-year marriage last week but despite claims the actress' concerns their six-year-old daughter Suri was to be subjected to auditing and sent to the Sea Organisation - a floating Scientology school - were behind her decision, the 50-year-old actor is said to think the claims about his religion are being made to ''hurt'' him.
A source close to Tom told TMZ: ''(Katie) was totally committed to Scientology. She had enthusiasm for it and would voluntarily and gladly participate in it when Tom was off shooting movies.
''This is not a fight over religion. It's being used as a way to hurt Tom.''
Despite Tom's apparent belief, Katie has reportedly stepped up her security amid fears she is being ''spied on'' by Scientology leaders, with her parents receiving hourly reports on her whereabouts.
A source told RadarOnline.com: ''Katie's father and mother are in constant communication with their daughter. They are being told what she is doing and where she is with Suri. One of Katie's bodyguards is also calling her father throughout the day and night to inform him of Katie and Suri's physical location and there is an electronic security log that Katie's parents receive that is updated hourly.
''Katie is taking these extraordinary measures for obvious reasons. She knows now that in the eyes of Scientology she is the enemy. Her father advised her to spare no expense in hiring the best security team possible. ''
Meanwhile it has been claimed Katie Holmes wants sole custody because she is worried if she shares custody she could end up being phased out of her child's life.
Katie is said to be determined to win the custody battle after seeing how little contact Tom's adopted children, Bella, 19, and Connor, 17, have with their mother, the actor's second wife Nicole Kidman.
A source told the Daily Mirror newspaper: ''Bella and Connor aren't that close to Nicole, and Katie is determined that she won't be cut out of Suri's life.
''Katie will not be relegated to a secondary role in her daughter's life. Period. And she is prepared to fight Tom in court.
''Katie isn't going to back down and she will do whatever it takes to ensure that she raises Suri herself.''
Katie is also believed to be worried about the influence the sci-fi cult Scientology, of which Tom is a devotee, could have on Suri.
The source added: ''Bella and Connor are devoted to their father and Scientology, and Katie saw this first hand, and this is one of the reasons she filed for sole custody.''
Katie, 33, has also filed for divorce in New York, as part of her strategy to win sole custody, as she believes courts in Los Angeles - the city where she lived with her husband - will favour joint custody.
Her break-up from Tom, 50, is said to have been meticulously planned, with her giving no clues she was going to leave her husband until the last minute.
The source explained: ''She was talking to Tom on the phone up until last week saying, 'I love you.'
''Her inner circle has been planning this and switching out cell phones since she was in China (in mid-June).
''When new cell phones arrived, then nobody could reach her.
''Her old best friends from last week don't have her new number, no email. She's unreachable.''
