Who made him the boss of them?
God, obviously. Allegedly. Who knows what those cardinals do, locked up in their super sacred seclusion. I'm sure it's all pious and devout. Nothing shady about an old men's club having a lengthy secret meeting to decide which of them gets to be the face of its abuse for the next decade or so.
Less sarcastically, the women he was preaching to were Dominican nuns, a catholic order of travelling preachers. He was also talking about Catholic nuns in general. They made him their boss by devoting their life to serving a church he's the boss of.
If they take issue with a man telling then what to do, the Catholic Church probably isn't the right place for them. Well, it's not the right place for anyone except senile chauvinists, but that's beside the point.

Childhood, eh? You can never go back.
You just need to keep in touch with your inner child. Failing that, you could become a priest and get in touch with other children.
