I Know How You Feel ...
Here's a great article ... http://nymag.com/nymetro/news/features/n_9932/
I've been where you are. My advice ... directly confront this man and say exactly what needs to be said. "Stop talking to me like that." The definition of sexual harrassment is in regards to unwelcome behavior. This man needs to know that you absolutely do not welcome his behavior.
Plan B, I'd communicate what you've experienced to the powers that be at this church and I'd suggust they educate this man and any others that may not understand sexual harrassment. In my experience, workplaces are must better equipped than churches, theaters, etc., to handle these situations, often even before they happen.
Take care of you. Don't be afraid to speak up for yourself. You'll save countless other woman from the experience. And so what if you have to exit the institution. If you do, I'd suggest writing about what you experienced there, anonymously if you wish or make up a name, and get it published locally.
I'm so sorry for your experience.
Take care of you.
