If you share a border with a different religion and find lots of priest/imans converting your population, the correct response is NOT defense. It is very hard to win, due to the way conversion is calculated. iirc, if both priest and iman can convert 5% each turn, it is actually 5% of the opposite religion. assuming you are a Chirstian city, 10k chirstians, 1k of muslims. An iman comes and start converting. The iman will be converting 500 per turn, while your own priest (not counting the church) converts at only 50 per turn. The 'invading' religion nearly always convert faster than the resident one.
What you should do to STILL build priest/iman units, but don't try to convert back your population. Go to the neighbouring country and start coverting theirs! Sooner or later, their priest/imans go back and 'defend' their religion instead of converting yours.
