There is no such person as Eros Christian.
Perhaps you mean what is Eros' Christian name? Eros wasn't a Christian, he was a primordial Greek God. His Roman equivalent was Cupid (also not Christian). Christianity began as a Jewish sect around the mid-1st century thus Eros pre-dates Christianity by more than 700 years (according to Hesiod, one of the most ancient of all Greek sources). Cupid probably evolved later but there are references as early as 340-320 BC.
