In reality, the so-called Pope had simply cut off his sense of smell. That's why he was unaffected by the stench in the old cemetery.
It should be mentioned that it wasn't a result of a soul skill or anything like that. The ability to selectively deactivate senses at will was unique to the Pope's body. Like flipping a light switch, he could turn any of his five senses on or off. This skill proved invaluable, especially in such a noxious environment.
