Would totally depend on what they did before “Jesus-ing” and how they are currently. If they are still into churchgoing, it’s a no. If they are now atheist, it’s interesting.

It would depend on the individual and his reasons for entering religion as a professional. Some come away broken. It's probably one of the most difficult things to confront for oneself. I might accept a friendship, but a romance might be another matter, if the priest has no experience with women etc.

Ex. (as in no longer a theist) no problem.

I'd never date a nun, because I'm trying to get me 'some,' and I may be far too old for the priest.

if they were female, i don't think id have a problem, depending of course on whether theyve awakened from their religion....

Why the opposition between a priest and a nun? Isn't the male equivalent of a nun a monk?

No problem. As a male I have very distinct preference for females, so I would go for the nun, though if she were a virgin I would have severe reservations.
Recently i became acquainted to a former Sino-TIbetan monk who is now a father of twins and works as a barman. By the looks of it he has made a rather complete recovery.

hmm just because they gave up the job, did they also leave the mindset behind?

I'd need to know more about them than just that.

I "dated" a priest...let's just say I should have worn socks...

Before I met my late partner I was on a dating club (as opposed to computer site). One woman I met had just come from a cloister and decided the life was not for her. She was interesting but still highly religious.
A number of years ago FFRF needed to expand their headquarters and was asking for some $2 million (they got more). One top contributer (and who a room was named for) was a former priest who left. He married a woman and they both were teachers. He contributed $250,000. He said they were frugal and didn't have kids (people always underestimate how much it cost to have kids). [ffrf.org]

Nope nuns were married to Jesus..too much baggage!

For me personally, an ex-nun might be interesting.... an ex-priest? Nope.

When I read the title of this post I thought to myself "this can't be good."

Friday's are happy days when the only meat you eat is nun!?

Are they also ex religion? If so no problem!

Only if they were indeed ex and were now at least agnostic atheist.

Same as anyone else..,but I come from a religious background and I moved far out from it! They could have done the same, probably more easily than I...

ok if she is ok I guess.

They must have seen the light
