But yet Origen plays a large role in this discussion about the correct translation.
One thing has occurred to me in this discussion. Why would Jews write their Scriptures, or copy them for that matter, in Greek instead of Hebrew?
First, they were commissioned to translate the Scriptures into Greek by one of the Ptolemaic Pharoahs.
Second, Hebrew was, for most Jews in the centuries just before and after Christ's Incarnation at most a liturgical language only, like Latin for the Latin church, pre-Vatican II, or Church Slavonic for the Russian Church. It was not the native tongue: Jews either spoke Greek or Aramaic.
The word 'synagogue' for instance is Greek, while the noted Jewish historian and philosopher Philo of Alexandria wrote exclusively in Greek, and seems to have read the Scriptures in Greek translation.
It is not entirely clear from this that the Jewish custom of praying in Hebrew only is not itself an anti-Christian innovation.
