I don't know if this will pass the editorial review, and I offer it in good faith and in good Faith. But there is no canon or no canon lawyer who can challenge this: 

There is nothing in the 'flow of life' that can inspire, humble, educate, challenge, or make a man feel like a child of God like holding a grandchild or making love to a grandmother. 

I'm not saying these are requirements for holiness or sainthood, but.....it does take some theological arrogance to challenge it without knowing or without trusting the unique charism of those who do. I think Pope Francis trusts. I am not sure how many prelates join him.
