In Ephesus, Paul began his ministry in the synagogue (think Jewish community center). Unfortunately, due to strong Jewish opposition, he was forced to leave and carry on his discussions in a new place, the lecture hall of Tyrranus. Here he focused his attention on the 12 disciples who wanted to learn more about the God of the Bible. He stayed here for two years before moving on to his next assignment. While this isn’t exactly a seminary, it seems to lay a foundation for the training of articulate Christians.
