I was late to the religion party, so my neighbour snuck in and converted all my cities to his religion. Now I seem to be unable get my own religion back.
In the previous edition, I could use a Great Prophet, or just rely on my Holy City's strong pressure, but neither of these options seems to be available in Civ 6 (I have no Great Prophets available under Great People, it seems like they are only used to found a religion now?).
I have thousands of stored faith, but any unit I buy will have the dominant religion (my neighbour's).
I've tried looking through the civilopedia, to no avail.
Has anyone found a way of clawing back your own religion from destruction?
