It was when he was in Ephesus in AD55 that Paul, learning that things were not all well in Corinth, wrote to the church there. This was to be his call to one of the greatest and most cosmopolitan cities of the ancient world - a rebuke and an instruction and a call for unity within the Church. William Barclay guides the reader through these letters and the story they tell, showing how "The Letters to the Corinthians", perhaps more than any of Paul's other writings, reveals the character of the man, his passion, humility, strength and zeal. These epistles are both a heartfelt appeal to the people of Corinth and a fierce defence of the Christian church.
