It’s already been disgusted how Mathew 18: verses 18 on showing that there’s not a cut and dry way to enforce a rule or law in another thread I started. But let’s look at verse 16 the verse they like to quote. The verse isn’t talking about having two witnesses to a crime or a wrong doing , it’s saying if you have a problem with a brother and he’s not willing to listen to your side off the issue to take some witnesses with you that agree with you to help establish that your point of view is in fact correct.
This has nothing to do with witnesses to a crime!!
