Do you know of Reformers who cry in the town square "Once Saved Always Saved" and then go out and lead a life of total depravity?
Well, I know of Luther who broke his vows by marrying a nun, a horrid thing in my humble opinion.
Many a Catholic pope, bishop, and priest has broken many a vow (commiting acts much more horrid than marriage) ... without any promise of OSAS.
True.
I've know priests who have married, perhaps not nuns, but married just the same. They're human. Humans should marry. Even God didn't turn his back on marriage for people who wanted to serve the Lord. He said it's better to marry than to burn, although it might be harder for them if trials and tribulations come.
