The Apostle Paul did not want first-century Gentiles to be circumcised and convert to Judaism. He said if they did that, they would be “obligated to keep the entire law.” Instead, he wanted them to understand that if they thought they needed to keep the Sabbath, get circumcised, tithe, or keep any other OT Jewish law, they were exchanging the freedom obtained through Christ for a yoke of slavery! He reminded Gentiles that they were not under the Law.
Two thousand years later, Christians are still being told certain OT Jewish laws apply to them!
Paul said he wished those who taught this would go cut off their own genitals.
I guess I don’t feel quite as strongly about this as Paul, but I do wish Christian pastors would stop teaching this.
