If he’s a Jain then that would explain a lot. Jainism requires an extreme philosphy of non-violence (called ahimsa) which forbids the harming of any living thing (including killing bugs). This would also forbid something like paying for meat. It’s more than just an ethical thing, Jains believe that such things bring bad karma and will affect them down the line.
Is this guy of Indian heritage? Was he born into this religion or converted to it. Jainism tends not to be a religion of conversion (because it’s practices are rather extreme) so there may be a cultural factor playing into this. He may have been sincerely offended, not just being sanctimonious, but that’s partially because you did not understand the extent of what this kind of thing means in his religion. He should have explained it to you before you went to dinner.
This changes it a bit for me. What I would do is ask him if there is any way you can help to balance out the bad karma he probably believes that he incurrred by paying for the meat (essentially, he truly believes he committed a sin).
Your husband still does not owe him an apology since he didn’t know what was going on with this guy’s faith, but it might be helpful to find out if there is some way you can help him do something good to make up for it. It’s not about the money, it’s about the bad karma incurred by paying for meat. Repaying the money will not offset the karma. Talk to your friend or to her husband directly and explain that your husband simply didn’t understand the religious signifance of charging meat to a Jain’s bill. It’s not your hubby’s fault, nobody told him, but this is more than just a self-righteous PETA jerk, it’s a legitimate religious problem in Jainism. It wasn’t about being offended by your husband eating meat, your friend’s husband thinks he had to commit a sin.
This can probably be repaired, but your friends are going to have to be more careful and more upfront about what kinds of things this guy’s religion will permit him to do and not do. Like I said, Jainism is a rather austere religion. It’s tough not to break any rules. I don’t think he’s going to get too upset about what you guys do as long as he isn’t forced (in his mind) to do anything sinful, himself.
