I don't know if I'd qualify as "orthodox" in your view, but just as a matter of opinion from hearing him preach on the Gospel, I'd venture to say yes. How good a Christian he might have been is a whole 'nuther debate.
If he preached Christ crucified dead and risen again for our sins, then that is the Gospel...and if he also believed that, then, I think he was a Christian. I sure hope so. And I hope there are cigars in heaven.
