I am playing on Prince difficulty and have managed to found my own religion. However, I found I was swarmed by missionaries from Japan and before I knew it my cities were all reverted back to my original pantheon. I am not sure what happened. I tried to purchase inquisitors and missionaries with faith to restore my faith back to my cities but I could not purchase any (No items are available to purchase with faith at this time). Is my faith doomed? Can I get it back and how do I do so? I am at turn 242, 1655 AD. Thanks!
