I would say to Pope:
Therefore you are without excuse, O man, whoever you are who judge. For in that which you judge another, you condemn yourself. For you who judge practice the same things.
Romans 2:1
It always sounds bad when people get the idea that they must purify. Most of the time it seems to lead to killing of the non-pure people. And in this case Pope is in my opinion doing exactly what he judges others to be guilty.
I see the Pope was also offering this to all Christians as well.
