Simon, what seems to elude you is the big picture, which is: that one of your holy, Jehovah-channeling governing body 'popes' was summoned by the Australian government. He appeared before thousands in a live broadcast, squirming, blithering, glancing at his watch, licking his lips (dry mouth is a physical sign of lying), and overall trying to defend the indefensible. He tells justice McClellan that he is there "to assist the Royal Commission." Bu11shite!! He was SUMMONED.
Pope Francis, on the other hand, was at least smart enough to admit, soon after his appointment, that he had a problem on his hands. He is now willingly cooperating with authorities to hold the abusing priests accountable, and to enact preventive reforms to keep these sickos away from kids.
I'm neither a Catholic nor a Jehovah's witness, though if I had to choose one over the other, as an outsider, it wouldn't be a hard choice.
