Josephus was born after Jesus died
What a spurious comment. Do you give yourself little stars for ‘gotchas’ you perpetrate at FR? ... And BTW, little solitary wave, there were still living in Josephus’s day probably hundreds of eyewitnesses to the resurrected Jesus. Are you aware of the Historical events by which Josephus became a Roman certifierd Historian since he was previously an ascetic Jew?
He still wrote about Jesus, even a description of him. Your mind is just closed to anything about Him. I pray for you that you will investigate with an open mind, for yourself. Blessings. mary
