RE: The rest of the list, not sure about Mel Gibson, are born Catholics.
I believe he is born Catholic. His father is in fact,an outspoken critic, both of the post-Vatican II Roman Catholic Church and of those Traditionalist Catholics, like the Society of Saint Pius X, who reject Sedevacantism.
My husband is a Catholic of the Society of Saint Pius X.
Me, not so much. I’m a non-denominational protestant. Needless to say, we often butt heads on religious matters. And no offense to anyone, but sometimes I feel the whole Catholic religion thing is more to please man, than it is to please God.
But that’s just me.
Mel Gibson is divorced but he is not remarried. And since he has split with his baby mama he is no longer an adulterer, and can presumably be admitted to Communion.
