Problem: Paul’s main point in Galatians can be summarized in his words, “If you become circumcised, Christ will profit you nothing” (Gal. 5:2). Yet Paul admits that he had Timothy circumcised “because of the Jews who were in that region” (Acts 16:3). Wasn’t this a contradiction to his own teaching.
Solution: Even if Paul were wrong here in his action, it would not prove that the Bible erred in its teaching, but simply that Paul erred. Paul, like any other human being, was capable of error. Since the Bible is the Word of God (see Introduction), it is not capable of erring in anything it teaches.
Furthermore, Paul’s action in having Timothy circumcised is not necessarily inconsistent with what he taught in Galatians, since the two cases are different. Paul was violently opposed to any who made circumcision necessary for salvation. But he never opposed it as helpful for evangelism. Indeed, Paul said elsewhere, “to the Jews I became as a Jew, that I might win Jews” (1 Cor. 9:20). However, when Judaizers insisted that “unless you are circumcised according to the custom of Moses, you cannot be saved” (Acts 15:1), then Paul took an intractable stand against circumcision.
“Then came he to Derbe and Lystra: and, behold, a certain disciple was there, named Timotheus, the son of a certain woman, which was a Jewess, and believed; but his father was a Greek: Which was well reported of by the brethren that were at Lystra and Iconium. Him would Paul have to go forth with him; and took and circumcised him because of the Jews which were in those quarters: for they knew all that his father was a Greek. (Acts 16:1-3)
