Marcion: The Man Who Invented the New Testament

Flip to the front of almost any Bible and you’ll find a table of contents split into two halves. Old Testament, New Testament. Most of us never ask who decided there should be a second list at all, or why the first one stayed. The answer runs through a rich shipowner from the Black Sea coast named Marcion.

One of the most gifted is a man from Egypt named Valentinus, and by one ancient account he expects to be made bishop. He wasn’t. Someone else got the job, and within a generation Valentinus had become a favorite target of the heresy hunters. Bentley Layton, whose translation of the fragments I’ll lean on throughout, says that if things had gone the other way, “the whole future of Roman Christianity might have been unimaginably altered.” ...
