The Church knew all about annulments. The fact is that Henry had no grounds for one, having specifically petitioned for a dispensation to marry Catherine in the first place. Every marriage should be as well-vetted as that one was.
Leo X’s affective disorders (if any) are a matter of speculation and in any case irrelevant unless you’re looking for a cheap drive-by slur.
Tell me, Romulus, what is the difference between what Christ saw in the temple of Jerusalem when he drove out the money changers profiting on animal sacrifices during the Passover and what Martin Luther saw when he went to Rome and saw indulgences being sold at the behest of Leo X? I see a lot of similarities...
