You can't say that; you're infringing on the Holy Father's religious liberty. :)
It's not merely his critics that sink their teeth into every momentary off-the-cuff remark made by Francis but his fanboys/girls (including the gender-neutral "fanenby" or "excessively-exuberant-over-Pope-Francis-person"), too -  "Who am I to judge," being but one example.
God forbid that you make any comparison between Francis and Trump... nowadays you can't even start by suggesting that both share a gender without getting someone in an uproar (see my prior paragraph).
