In Paul’s letter to the Galatians, he tells them about false brothers who had crept into the church, teaching the falsehood that in order to be a Christian, in order to be saved, one had to be circumcised. This was a distortion of the gospel (Galatians 1:7), a different gospel entirely. A false gospel.
When this false gospel reached Paul and Titus, here was their reaction:
to them we did not yield in submission even for a moment, so that the truth of the gospel might be preserved for you. – Galatians 2:5
Paul and Titus gave no room for this falsehood to grow. And, in fact, it’s because of this letter (among other places in the New Testament) that we know this circumcision claim and others like it to be false, millennia later.
Brothers, sisters, truth matters. It’s not popular these days to stand for truth. In our culture, truth should be what is true for you and what is true for me. And if I tell you that your truth is wrong, I’m an ignorant bigot.
Nevertheless, we must stand for truth, fellow ignoramuses. We must stand for truth especially where we are preserving the truth of the gospel for others, by His grace. This is why we must publicly reject, in gentleness and love, but with boldness, anything that claims to be gospel, but is contrary to what the Scriptures teach.
We must warn the sheep against the gospel that if you believe in Jesus, you will become rich and healthy. We must demolish arguments that sacraments are required for salvation. We must declare false that you can one day be god of your own world. We must not yield in submission even for a moment.
