Caught between respect for family and the desire to preserve their children’s autonomy, the parents face a painful clash of values that threatens to unravel the delicate balance they’ve worked so hard to create. The grandparents’ well-intentioned but intrusive actions reveal a heartbreaking tension — a desperate attempt to save what they believe is lost, even if it means overshadowing the very freedom they once cherished.

My wife and I are raising our children without religion. We’ve taught them it’s a thing that exists and always answered questions about it as honestly and truthfully as possible “They believe X…
Etc.”, but we don’t want to push one on them and try to limit exposure outside of media and other people freely practicing.
My parents are devout Christians and love our children just as much as we do. I can count on one hand the people I trust with my kids and they’re on the list.
However, they simply don’t respect the boundaries my wife and I have set, assumedly because they believe they’re saving my children from the eternal damnation they couldn’t save me from.
I feel their hearts are in the right place, but the last time they visited for summer (we live in a different state from my parents) they came back speaking like we’d been raising them as Christians from birth.
“God says this and that”, etc.
The most recent conversation went like this:
“Why don’t you believe in God, daddy?”
“Because he’s not real sweetie.”
“But Grandma and Grandpa say he is!”
After this one I told my parents that if they keep doing this they won’t get to see the kids without my or my wife’s supervison.
They told me I was being hateful and it was “wrong to keep a grandchild from her grandparents just because you don’t want them to hear about the Lord”.
Conclusion
The original poster (OP) is experiencing significant conflict because their deeply held values regarding their children’s religious upbringing are being actively undermined by their devout Christian parents. The OP attempted to maintain parental authority by setting clear boundaries about religious instruction, but the grandparents repeatedly disregarded these rules, motivated by a desire to save the children from perceived eternal harm. This clash has resulted in the OP escalating the consequence to supervised visits, leading to accusations of being hateful.
Did the OP overstep their authority and act unfairly by threatening supervised visits to enforce agreed-upon boundaries regarding their children’s non-religious upbringing, or were the grandparents’ persistent actions a fundamental violation of parental rights that justified this firm response?
Here’s how people reacted:
You can’t shield your children every minute. This is like the inverse of the overbearing Christian parents trying to shield their children from secularism. At some point they’re going to be come in contact with it and you’re best bet is to explain to them YOUR beliefs and why you believe they’re the truth.
Because if they’re truly trying to convert your kids (which is vastly different than exposing your children to their own religious habits and thoughts), then NTA.
But if you’re equating conversion to normal exposure and questions that your kids have about people who have different thoughts and practices than you, YTA in a major way.
What, if any, religion, you want to teach your kids absolutely falls in the reasonable category. Don’t let the “atheism” element be a distraction. If you married someone of a different religion and wanted to raise your kids that way, a grandparent not respecting that would be equally bad.
YOU won’t be the reason your kids are denied seeing their grandparents. It’s the grandparents making that decision by not following your rules.
That if you are correct, there is no God, then there are pretty mild consequences for being mistaken. If on the other hand they are correct, and there is a God, maybe there are more significant consequences for being wrong.
But when you whip it out in public, or start jamming it down children’s throats – WE HAVE A PROBLEM.
Let them decide for themselves, if they decide Christianity, then that is just how it is
