No one can apply to be pope of the catholic church.
Correct. In fact, even to be a bishop you have to state as part of the ritual that you do not wish to be a bishop. (Many do of course.)
(Am off to read the article now. :) )
Not the point of the story at all. Read before commenting.
Sure, anyone and everyone can apply, to basically anything. Sometimes you can even get into stuff they didn't think they accepted applicants to. Most of the times you get ignored though.
Technically, all adult Catholics can become Pope. But realistically it's just one of the cardinals, which means you need to become a bishop first, which means you need to become a priest first, which means you need to be celibate (x). This guy has a wife, according to the article, so he cannot become a Pope.
(x) this is technically not true for some Anglican orders that later became Catholics? Maybe? (I never remember the rules of the ordinariate.) So maybe he could first become a priest in Anglican Church, then switch to Catholicism, then become a bishop, then a Cardinal, then a Pope? It's a long shot though.
edit: ahhh the married priests in Ordinariate cannot become bishops. So he would need to have first his marriage annulled I guess.
