The primary literary parallel Philostratus is drawing is between Apollonius and Pythagoras, not Jesus. He explicitly says Apollonius 'performed the same feat as Pythagoras' at Ephesus. Apollonius even claims to be a reincarnation of Euphorbus, a fighter at the Battle of Troy. Any apparent parallels to Jesus are incidental or deliberate anti-Christian swipes by Philostratus.
