This is the Problem

[RobbyPants]

That non-Christians think that the Old Testament is a Christian text and true believers of Christ are somehow bound to it by letter.

OT was a Jew law and does not apply to Christ believers anymore. That does not mean we can use the good things from it and discard the rest. I believe in the 10 commandments - does not mean I have to follow the OT.

This is the problem: your iron-age religion chose to piggy back on a rather barbaric bronze-age religion. That's just something you and your apologetics are going to have to cope with.

Also, when quote-mining Jesus to say that the OT doesn't apply, it's not honest to ignore the next verse where he says that it does apply until the heavens and the earth pass. Oops. Learn to Bible:

Matthew 5:17-18

17 “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. 18 For truly I tell you, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished.
