The argument of undesigned coincides first coined by William Paley (1743-1805) is a brilliant demonstration of the historicity not just of the 13 letters of Paul but also of the book of Acts. The evidence has not been refuted. They have simply been forgotten by modern scholarship. That is why Dr. Lydia Mcgrew decided that these arguments needed to be brought to the attention of a 21st century audience. She does this in her study Hidden in Plain View . If as Paley claims the historicity of Acts is demonstrated in this way Acts and the Letters of Paul interact through undesigned coincidences, then much of the literature of the Paul within Judaism School will need correcting. Their ideas are built on the idea that Acts can almost be ignored when dealing with Paul. Paley was from a period of academic geniuses who brought out studies which soundly demonstrated the historicity of the Old and New Testament. The writers include Isaac Newton and William Whiston.
