Anyone can call themselves Catholic, that doesn't make them so.
Warhol did not live in a country, like China, where being Catholic invites persecution and would explain a perceived need to be a closet Catholic.
IF he was a closet Catholic he had no excuse for being so, but his ɧoɱosɛҳųαƖ life speaks otherwise. Contrary to his own claims to have remained celibate, numerous men have come forth to contract him, too many to be ignored.
Only God knows where his soul is now, and only God cares.
The End.
