Will the world eventually become Catholic again?

At one time civilization as a whole used to be Catholic. The then known world at the time, which was Europe, was Catholic. Will this ever happen again in the near future? Will all the Protestants eventually return back home? Will all the Orthodox return back into the fold and believe the universal jurisdiction of the Pope? I've been reading this TAN book titled Catholic Prophecy by Yves Dupont. The book covers the Great Catholic Monarch, the Holy Pope, and the period before Antichrist. It mentions that the majority of nations will be converted to the faith of Christ before the end of the world.
