Thanks for that. As I read it, it rather weakens your claim that the Christians borrowed physical resurrection from the Zoroastrians.
"Thus, even scholars such as Boyce, who strongly assert Zoroastrian influence, are inevitably struck by the extent to which Jews reinterpreted and developed very different conceptions than those expressed in classic Zoroastrian sources.
This feature of Jewish adaptation illustrates the difficulties involved in citing "direct" influences, even in the favorable comparisons ... The Hellenization of Zoroastrian traditions may also have distorted any presumed Jewish reception of their eschatology. If Judaism reinterpreted Zoroastrian contributions, it probably did so in dialogue with other kinds of non-Zoroastrian traditions ...
Rather than seeking a "direct" influence, it seems more useful to consider the larger contextual features of encounter between Zoroastrian eschatology and early Jewish thought... "it may have been as part of this oriental anti Hellenistic reaction that the Jews came—if they did—to find Iranian conceptions useful for the expression of their own religion.”
In this sense, Persian influence may have made it plausible for Judaism to reinterpret the imagery of earlier prophetic texts in a more literalizing way, even as the Hellenistic empire made it imperative to do so."
As I said, a melting pot ... a lot of 'may haves' but as the text implies, if there is cross-over, its a dialogue with one tradition that enables another to refine its own perspective in light of what it already believes, rather than believing in something new, adopted from an extrinsic source.
And, of course, the followers of Jesus had no concept of physical resurrection with regard to Jesus Himself until after the event, as it were, as even John, the most insightful among them, points out that the empty tomb was something of an epiphany with regard to how they understood Jesus, despite His prior prophetic utterances and intimations – and Paul did a lot of work to unpack what the resurrection meant, which is not at all part of the Zoroastrian belief system.
