For some strange reason this issue comes up a lot in my dealings with fellow Christians, mostly IRL, but also online. And more than is necessary has derailed a fruitful conversation and left it dead in the water, almost exclusively when the other Christian is a hardline believer in Saturday being the Sabbath, and Sunday being such a perversion that it makes them agitated to the point of disengaging.

I'm a relatively new Christian, always seeking to learn more from others regardless of their beliefs, and I find it baffling how often this topic shuts down folks who are typically among the most Bible literate I engage with. I've seen it deflect from great conversations too often. It's just weird to me.

I did some basic research on this, and AFAIK God never handed down a stone tablet establishing a calender, and the Hebrew calender (and early Roman calender) coincided with the earlier Babylonian calender, and the young Christian church began celebrating Sunday to honor the resurrection, and later the Roman Constantine calender established Sunday as the 7th day. Am I missing something? Why do some find it so overwhelmingly necessary to, seemingly obstenately, observe Saturday Sabbath, and WHY does it so often happen to cause these people to get so angry to the point of distraction? Why is following the Constantine calender a perversion, but not the arbitrary Hebrew calendar?

I realize this is just my experience, but it's an overwhelming experience and has often frustrated me. I do not mean disrespect, but I believe the day is not as important as the ceremony being celebrated with the body of Christ and I would like ammunition to evaluate situation better, and frankly argue against it. Without exception, I haven't met a person whose spiritual life has been improved by this belief; it has kept all of them away from church participation as a result. And honestly, their outward spirits reflect that.

Thanks, I'll check back after work in 12 hours, lol.

Apologies for typos and grammar. I'm bad at phones.

EDIT: I ask here respectfully as honestly, some GREAT Christian practitioners and scholars are here. It's a blessing!
