So how would your life change if her remains were found and she was genetically determined to be the mother of James? In my case, if it was determined she was an eternal virgin I would be surprised but it wouldn't affect my faith or beliefs. You didn't answer my question about how your church would feel about testing.

You didn't answer my question about how your church would feel about testing." Taking the last question, first. Her remains won't be found. That's our point. She is in Heaven, body and soul. If you truly found her remains, then the Church would have already been proven wrong in a fundamental dogma -the Assumption- and any testing, per se, would be irrelevant.
Thus, before we even get to testing, finding her remains would -to answer your first question- lead me to doubt what I believe to be the Body of Christ, i.e. the Church, and would probably occasion a significant spiritual crisis.
