Well, I tried to Google this for you and I could only find Ron Reagan Jr’s name on “lists of celebrity atheists” so I think the answer is likely “no,” but it’s the internet, you know? I did find this recent snippet of a
Salon.com interview with Ron Reagan Jr that seems to be fairly anti-religious:
*Reagan says his mother shares his “distrust of some of these [Bush] people. She gets that they’re trouble in all kinds of ways. She doesn’t like their religious fervor, their aggression.”
Reagan says his family feels particularly alienated from the Republican Party over its opposition to embryonic stem cell research, which could have significant benefit for Alzheimer patients like his father. “Now ignorance is one thing, ignorance can be cured. But many of the Republican leaders opposing this research know better, people like [Senate Majority Leader] Bill Frist, who’s a doctor, for God’s sake. People like him are blocking it to pander to the 20 percent of their base who are mouth-breathers. And that’s unconscionable – there are lives at stake here. Stem cell research can revolutionize medicine, more than anything since antibiotics.” *
His step-sister, Maureen Reagan, on the other hand seems to have been a Catholic. She apparently died recently and I found her obituary online and it listed that the funeral would be at St. Francis of Asissi parish.
That’s all I know, other than that Reagan Jr lives in Seattle (Magnolia I think) not a particularly Catholic-friendly town.
