Acts 18:7-11 (KJV) (emphasis added)
7 And he departed thence, and entered into a certain man's house, named Justus, one that worshipped God, whose house joined hard to the synagogue.
8 And Crispus, the chief ruler of the synagogue, believed on the Lord with all his house; and many of the Corinthians hearing believed, and were baptized.
9 Then spake the Lord to Paul in the night by a vision, Be not afraid, but speak, and hold not thy peace:
10 For I am with thee, and no man shall set on thee to hurt thee: for I have much people in this city.
11 And he continued there a year and six months, teaching the word of God among them.
What might we be able to conclude regarding the Corinthian Assembly forming out of a Jewish synagogue? Does this unique beginning speak at all to the way in which Paul dealt with them as a church, or of their particular problems or successes as described in 1 and 2 Corinthians?
