Also, in the early days of Christianity there have been some popes of North African origin - nothing afaik has been recorded about their skin colour (race as a concept didn't really exist back then, at least not in the way we today think of it), but it would be weird if they weren't at least Arab or "brown".

The Catholic church is also pretty openly sexist when it comes to who is allowed to hold positions.
And the comparison is besides the point really, in the Catholic church there are rules against women becoming popes, in the US there are none against women becoming president, and there haven't been for a long long time - yet no woman has ever been president.
