Acts 15:1

The Jerusalem Council

15:1 Now some men came down from Judea and began to teach the brothers, “Unless you are circumcised according to the custom of Moses, you cannot be saved.”

Acts 15:9-10

15:9 and he made no distinction between them and us, cleansing their hearts by faith. 15:10 So now why are you putting God to the test by placing on the neck of the disciples a yoke that neither our ancestors nor we have been able to bear?

Galatians 2:3-4

2:3 Yet not even Titus, who was with me, was compelled to be circumcised, although he was a Greek. 2:4 Now this matter arose because of the false brothers with false pretenses who slipped in unnoticed to spy on our freedom that we have in Christ Jesus, to make us slaves.

Galatians 6:12-13

6:12 Those who want to make a good showing in external matters are trying to force you to be circumcised. They do so only to avoid being persecuted for the cross of Christ. 6:13 For those who are circumcised do not obey the law themselves, but they want you to be circumcised so that they can boast about your flesh.
