Joke regarding the nature of at least catholicism that is premised here in the meme. The concept that, St Thomas Aquinas, who is arguably one of the more acclaimed theologians in the catholic church post Council of Nicea.

He frequently establishes premises that sex in and of itself is not sinful, however any take on sex that is for the purposes of pleasure/gratification is sinful and should be shunned. Thereby one could state that being fully human and also divine, Christ was not immune to but would not have pursued the concepts of pleasure or deriving pleasure through sex.

So the posit Im making is a joke within the joke. Basically, the position is one wherein this guy didnt read that guy which refuted the point. Hardy-har-har.

It should be noted, more modern versions of catholicism dont really follow these principles any longer on the premise that sex between a man and wife is good because it can result in conception and they experience their love which gets them closer to god’s love (not my personal view, more parroting some of the more modern beliefs). Additional note, StTA also kinda eludes to this but in a round about way.
