When Paul came to Corinth in Acts 18, he went into the synagogue as was his custom. The synagogue represented the church system of that day and the religious tradition of the fathers. Fast forward almost 2000 years, the religious “church world” system of today represents what we have seen as truths that have been revealed the last 500 years!
Paul preached Christ and his kingdom to them and was opposed and rejected. What did he do? He went to the house of Justus, who worshiped God and whose house “was next door the synagogue.” (I. Co. 18:7) Then verse 8 days, “Then Crispus, the ruler of the synagogue, believed on the Lord with all his household. And many of the Corinthians, hearing, believed and were baptized.”
Now, in that day, here was this new religion and the Jews still looked at themselves as the people of God! Again, come to this day: Did Paul “split” the assembly or did the gospel of the kingdom separate those being called out? And, how should apostles handle this today?!?
