2 Corinthians 10:13 But we will not boast of things without our measure, but according to the measure of the rule which God hath distributed to us, a measure to reach even unto you.

It was the Apostle Paul who had come to the city of Corinth to preach the gospel that saw to the establishment of the church in Corinth. This work was established as it were through the working of God in the Apostle Paul’s ministry. It was during his 2nd Missionary journey that the church was started.

Recall Luke’s record in Acts 18 where the Apostle Paul departed from Athens to Corinth (Acts 18:1). He abode with Aquila and Priscilla who were tentmakers. On the Sabbath, he would make his way to the Jewish synagogue to preach the gospel. He was opposed but God was with him to save Justus who lived next to the synagogue. And Crispus, the chief ruler of the synagogue also believed with all his household and many other Corinthians hearing the gospel believed.
