The catalyst for the Tom Cruise-Katie Holmes divorce appears to have been fear of their daughter being immersed in Scientology, according to reports.
Specifically, a Scientology organization known as Sea Organization (or Sea Org), where the religion is taught to kids as young as five, was the final straw.
Kids can be sent to live there without their parents to learn the highest levels of the belief system. Tom is said to be a huge supporter; Katie not so much.
Even before she filed for sole custody of Suri, Katie and Tom had been arguing over the little girl's indoctrination into Scientology. She's now six years old.
Sea Org has been often likened to a boot camp; ex-Scientology members have been outspoken against its military-like conditions on several occasions.
Members of Sea Org must sign "a one-billion-year pledge to symbolize their eternal commitment to the religion and it is still signed by all members today."
When Holmes and Cruise first hooked up in 2005, Jessica Feshbach, who had been with Sea Org since 1994, became her Scientology handler/chaperone.
In one of Katie's first interviews after getting together with Tom, Feshbach was described by a writer for W magazine as "cold-eyed" and "a third-wheel."
Katie, 33, reportedly felt the only way to save Suri from being shipped off to Sea Org was to file for divorce from Tom, 49, and seek sole legal custody.
The church denies, meanwhile, that the actress is being stalked by Scientology minions around NYC, a report that circulated over the weekend.
