So what’s the primary reason for Katie Holmes wanting to divorce her former soul mate Tom Cruise?

Sources say it’s all because of Tom’s strong ties to Scientology.

Katie is reported to be fearful Tom is gonna bring their 6-year-old daughter Suri deeper into The Church — which probably explains why she wants FULL custody.

TMZ reports Katie has never been fully committed to Scientology, even though she’s had ties with the church.

It’s been reported that the couple had been arguing over Suri — that she’s now of the age where Scientology becomes a significant part of her life.

Katie is filing for sole legal custody and specifically because she does not want Tom to control decisions relating to religion.

Goodlawd.
