It seems no matter how meticulous editors and proofreaders are, invariably mistakes are missed. I found this one in Frederick J. Murphy’s Apocalypticism in the Bible and Its World, p. 94.
There was no empire-wide persecution of Christianity until the middle of the third century BCE.
Did you catch it? BTW, this is a great book–get a copy and read it if you can.
