Here is a concept that I suspect will be entirely beyond your ability to grasp. There is nothing in the Bible that allows you to tell Christians what they are allowed to believe. The reason I know that for a fact is that, unlike you, I have actually read the entire bible,. not just the parts that allow you to claim that the neither the Old nor the New Testament contain any instructions telling believers not to associate with people. I can name 5 off the top of my head that prove you are wrong.
They show their ignorance every time they start one of these ridiculous threads.
And yet, neither of you has provided even one single verse to back up your claims.
What you are promoting here is just patently un-christian. It goes against the very fabric of what Jeshuah taught. If he is really your Messiah, you sure don't show it very much.
Or do you think that Christians have never sold stuff to sinners in the past? Really? Can you possibly be that naive? Really?
BTW, you might want to look up the real meaning of ignorance. It is not necessarily an insult, but you are using it wrongly.
