The big issue of Paul's day was circumcision. It was the subject of more debates and the cause of more bitterness than anything else. Even the big name preachers were involved. Paul and Barnabas engaged in such a heated dispute with some brethren from Jerusalem, that it was decided to call a central conference in an attempt to resolve the matter.
Circumcision is no longer an issue.
It seems a little ridiculous to us now that it ever caused such a furore. Now we are confronted by new issues which have supplanted the old, and which seem as grave and important to us as did the others in days of yore. There are some things we seem never to learn. Either circumcision or uncircumcision. We say that a thing has to be either right or wrong.
