Just running through my memory bank quickly, I can only recall ever encountering one (someone from this forum). Okay, maybe two.
Forget about the churches that I've been to.
This may sound over the top, but I honestly doubt that I've ever stepped foot in a church where even the "pastor" (read: hireling) was saved.
I've checked out some "Christian Dating Sites" in the past (I'm done with those for good), and, even then, I was literally only looking for a "friend" or "activity partner" (You could list on your profile page what you were after). Well, I got some interest, but things always went south as soon as I mentioned that I didn't believe in fornication or pre-marital sex. Yes, that's what all of the women that I ever encountered on such "Christian" sites were after.
Whatever.
Anyhow, I'm always happy if anybody finds true love...
