If the noise is of the mic overmodulating, then no, it cannot be fixed completely.
One thing you might want to attempt in order to lessen the effect is to look at it in Spectral View and see if you can use one or two of the tools available to lessen its effect.
If it's a loud plop, and there aren't too many of them then there are a couple of things you can do to reduce the effect of them, even though you won't fix the problem completely. Spectral view won't help you very much though, because these usually involve a very low frequency shift at an overload level, and it's this effect you need to get rid of.
First thing you do is to use a high pass filter to get rid of everything below about 100Hz or thereabouts. This alone will probably improve the situation a lot. Then, on the bits that are still bad, highlight them and apply Auto Heal to them, possibly more than once. Beyond that, there's not a lot you can do, short of getting the priest to learn to ADR himself, and fixing it that way. This is something that Audition CS6 is now very good at!
