Tom Cruise, a high-ranking member and proponent of the Church of Scientology, has banned ex-wife Nicole Kidman from his son’s wedding.

Connor Cruise, 24, a Scientologist like his movie star dad, will soon be marrying his Italian girlfriend Silvia – but his mother won’t be welcome at the wedding.

“Tom is behind this and what he wants is as good as law,” a source told RadarOnline.com. “Tom made the call and Connor followed.”

Connor, a former DJ who is now into deep sea fishing, “worships the ground his father walks on” the source added, claiming he would never disobey the 56-year-old actor.

Insiders say Tom “adores” his future daughter-in-law and is happy his son is settling down with a fellow Scientologist.

Nicole left the controversial “religion” of Scientology in the ’90s before her marriage to Tom ended in 2000.

Last November, the actress spoke about her relationship with her oldest children, telling the Hollywood Foreign Press Association, “They are able to make their own decisions. They have made choices to be Scientologists, and as a mother, it’s my job to love them.”

Ex-Scientology member actress Leah Remini wrote in her book that Kidman was labeled a “suppressive person” or “SP” by the church after leaving.

RadarOnline’s source said, “First, Tom would never even consider inviting Nicole to Connor’s wedding because she’s considered a ‘suppressive person’ by the church — and, second, he doesn’t want her there.”

Connor’s fiancée is apparently dubbed a ‘Scientology Princess’ as she also follows the religion along with her family who moved to Florida from Italy.

Cruise is considered a ‘deity’ within the Church of Scientology and lower-ranked members are reportedly encouraged to see the actor’s films multiple times, according to Remini, who was a Scientologist until 2013.

Cruise is second in command to Scientology’s leader, David Miscavige.

The actor moved to Clearwater, Florida, just a block from the Church of Scientology’s spiritual headquarters, in order to be closer to Miscavige.

The Church of Scientology, an organization created by the science fiction writer L. Ron Hubbard, has been branded as a very expensive cult because it forces members to live within walled communities and never leave.

Scientology boasts multiple A-list actors and business magnates in their membership, and it follows a hierarchy system in which its members are separated (and treated differently) depending upon how they rank.

In addition to being worth billions of dollars with massive real-estate holdings, Scientology has been known to attack detractors and cover up the misdeeds of some of its most prominent members.

“There is no other religion that I know of that requires two and a half hours of your day, a quarter of a million dollars minimum, and at least 40 years of your life,” Leah said on her show last year.

Scientology was founded in the 1950’s, after the publishing of Hubbard’s self-help book Dianetics.

It’s built around the ideas found within both Dianetics and the science fiction genre for which Hubbard was known.

Scientology has faced a storm of public criticisms over the past decade, much of it done by former members of the group.

L. Ron Hubbard’s great-grandson says Scientology is a “dangerous cult” that ruined his grandfather’s life and cast a dark shadow on his family.

“My family sees Scientology as absolute poison,” Jamie DeWolf told Page Six. “It’s a dangerous cult.”

DeWolf’s great-grandfather, L. Ron Hubbard, created Scientology, and his grandfather, L. Ron Hubbard Jr., was a high-ranking member for most of his life.

“But he became disgusted about what he was seeing behind the curtain, so he left,” DeWolf says. “For the rest of his life, he was hunted. And he couldn’t even have a relationship with his father.”

The Scientology founder “became more and more unhinged in his last days,” DeWolf claims. “He was lost in his own little wonderland, surrounded by this armada, this dark security force. He was totally lost.”

A Scientology spokesman denied DeWolf’s claims.

The Church of Scientology’s “Super Power Building” is the largest building in Clearwater, Florida.

The Clearwater Scientology headquarters, where Cruise now lives just a block away, is known as the Flag Building, or Super Power Building.

It is a facility where top-ranking Scientologists can receive a VIP course called the “Super Power Rundown”—a series of auditing processes that comes with a price tag of approximately $30,000 and, according to leading Scientology expert Tony Ortega, may promise its recipients “infinite power.”

According to Fortune, about 25,000 Americans consider themselves Scientologists.
