Ask her about her intimate sex life . If she can ask you personal questions about you , you can ask her personal questions about her . Usually works for me .

I often tell them quite sincerely,

"You are of the belief that you have the key to the true nature of the universe and all of existence based on what you consider revealed knowledge by a divine being. Instead of being happy with that, you seem more worried that someone else doesn't buy into your particular mythology. Even if you think you're making your appeal out of concern for my well-being, it won't work. I'm familiar with your belief system and reject it as being logically inconsistent and unworthy of serious consideration. And I can't pretend to believe what I don't just to be safe. Your God would know."

Look bored and mildly disgusted, then say "I NEVER discuss religion or politics. I was raised to believe that to do so is LOW class." Then STARE at them like they are just about to confirm your suspicions about them. If they try again, stare again then ignore. You don't have to answer unless you want to get pulled in to the stupidity.

“Never argue with stupid people, they will drag you down to their level and then beat you with experience.” Mark Twain.

Thank you all. I haven't laughed this hard in a long time. I'm feeling better and emboldened..,

Yes, I have a response. Works a fair share of the time.

"Do you believe in (fillintheblank)?"

"No, I don't. Do you believe in Shiva?"

That is usually followed by a brief silence punctuated with mumbles. If they know anything at all, they will then say they don't.

I then say, "There ya go."

"I don't believe in an invisible being that resides somewhere beyond the clouds," I say. "I don't pester Christians about their religion. Stop bothering me."

Ooo fake ass southern princess... IF there is a next time & she brings up religion, just say. "Oh...I was brought up that polite company doesn't discuss 3 topics...religion, politics, & sex. Let's not open that can of worms, shall we. I would really hate to start asking you about your strange bedfellows", chuckle and abruptly change the subject. If she tries to bring it up again, look her dead in the eye & say, "bless your heart, don't you know we've already had this conversation. It was uncomfortable & uncalled for the first time. This time it's down right unwarranted & rude." (Bless your heart = southern way to call someone stupid)

If she doesn't get the hint, be polite, say your good-byes & call it a day. You may also want to let your ex's widow know this person is an unwelcome 3rd wheel.

i think "go away" is a good first parry. if that doesn't work, "go the fuck away" is a bit stronger.

I usually tell them believing in the afterlife is just a coward's way out of having to face the reality of death. Then I keep talking about death and the finality of it and how we will all be forgotten when those who know us die too. They tend to want to change the subject when you remind them death is real.

If god exists, I'd rather go to hell than be with you for eternity.

You're nicer than I am. I don't try to pretend that I have anything for them
but contempt.

However, in answer to your question, you can try a few things.
One is to show them you know their bible better than they do.
Ask them if they mix their fabrics? Ask them if they work on Sundays?
Ask them if they're aware they aren't allowed to get divorced or tattooed?
Ask them if they know that god gave directions on how to perform abortions?
Ask them how it's okay to cherry-pick what they'll follow in the bible, and what
they'll ignore?
Ask them how it's remotely okay that they disrespect ANY of their god's creations?
You know like women, homosexuals, children, the Earth?

Demonstrate that you know the history of the bible and christianity better than they do. They really HATE that.

In situations like this which do not happen so often in the UK. I generally say something like "Please don't go there. I understand and respect you view. I would appreciate it if you would do likewise and drop the subject, so we can still converse as friends"

Start talking to them in that fake ass tongues that they claim was sanctioned by the Holy Spirit. Have a good conversation and try to keep from busting out in laughter.

Ah yes, the ultimate bane of all Human existence, the 'Born Again Christian' spoon-fed on falsehoods, thrive upon self-delusion, spreading their virus-like disease where ever they go and completely mindless to the harm they are doing to everyone around them.
Sadly, I have one of those for a neighbor and am often accosted with his 'preachings' and ministrations.
There isn't a whole lot you can do with them unfortunately except to remind them that a 'Christian Lobotomy,' just like a surgical one, IS irreversible.

Do you believe in ?
Why not?
There are books about .
People have seen .
There are organizations devoted to .

Insert "ghosts," "sasquatch," "the Loch Ness monster," or any other mythical creature you can think of. After they've responded to all those lines, simply say, "Now you get it."

I avoid these discussions at all cost. If they don't let it go. I say the truth. I don't believe in zombies. That always shuts them up. Ask if they believe in zombies first . They shut up.

I'd suggest learning some bible quotes. [evilbible.com]
Quotes that remind them how nasty their god is. And when they say 'oh that's the old testament' Say....."oh did jesus die for gods sins as well??"

If I'm in a good mood and feeling kindly toward the individual, I say something like, "I don't believe in a cranky old man with a beard as the supreme being, anything beyond that is not within my ability to comprehend." Otherwise, I just say GFY.

Wow, so many great suggestions, and I understand you were a bit "trapped" as you met with a friend for lunch. If you did not learn an outstanding reason for bringing the bornagain along, I would certainly request she doesn't repeat that stunt.

My go to is from Douglas Adams.
Isn't it enough to see that a garden is beautiful without having to believe that there are fairies at the bottom of it too?

Whoa freaky could lie say Jewish like Jesus Christ watch her turn purple lol or even worse say hail Satan watch her run for her life or best say none of your business shut up

Go Stoic, and worry only about what you can control. Though I'd make it clear to your friend not to bring her along again.

Fuck off??
