Maybe he’s lost his mind because on one hand he claims to be a Christian and on the other hand is mired in sin — his ongoing adulterous relationship with this woman is just one example. Such tension — and the energy poured into denying the Holy Spirit — drives you crazy.
He needs to leave his religion, repent, and turn to Christ. Christ will help Mel come to his right mind.
Mel, Go back to church—go to the first Roman Catholic Church you can find and seek out the confessional. You were drunk, angry and placed in a position where you lost it. I will still go to your movies—I liked Errol Flynn’s films and he too hated Jews. Next time make a religious film. Maybe something on The books of Acts. Maybe Quo Vadis. Find forgiveness in good works. Use your God given talents to bring people to Christ.
