I've written a long post responding - and I could babble on it for ages as I've overstudied it and find it interesting from a historical / sociological perspective, but people have debated the church's role in abuse and biblical meaning for centuries & that gets tiresome and as you said much of it is out of your hands so I don't want you to feel I was expecting you to defend old stuff as I was more interested in your perspective of stuff now within your church so, I'll try to ask a more light question that's more fun that my meandering geeking out response - what is your favourite book of the Bible to read & why? (I lean towards Ecclesiastes, it can be depressing but I think it's very beautifully written and the push to find and choose a purpose is important however we do so. I also like Job a lot as an interesting story and a good starting point for a lot of discussions on ethics and life).
I'm aware evangelicals are not all one group - as I said, I previously was in one. I was in for quite some time, born and raised with a grandfather who helped build churches and train evangelical ministers and missionaries of multiple denominations. That's why I have way too much Bible knowledge and why I'm interested in how some are now handling the abuse scandals coming out worldwide - many churches among other places use the confidential closed door method and sometimes that works and sometimes that's used to hide things.
They're not all the same group and they're all making different choices which is why I asked for your experience particularly because it will be different than if I asked, say, someone in the American Nazerene movement or a member Evangelical Fellowship of Canada (I specifically used ones not big in the UK that I know of). With many evangelicals and many more ex-evangelicals calling out that there have been decades of many evangelical churches hiding and protecting abusers - particularly those who were or related to or otherwise close to those in positions of power - it's expected that those in both groups and beyond would want to know what any church under the evangelical umbrella is doing about it now that these are finally coming out. I find asking individuals involved tend to get more information than getting the official statements. Much like any other large group, corruption and nepotism happens and with it coming out as it is with fresh stories practically every week, many evangelicals and ex-evangelicals are trying to challenge the power systems that has made it so easy for it to happen. The evangelicals are no where near alone in this issue but having been raised among evangelicals but having no contact (having been shunned which I know few evangelical denominations still do), I was curious if the abuse scandals worldwide were having much impact in evangelical churches for those still in it.
Personally, with my experience and what we know about the abuse scandals so far, I think more evangelical denominations need to make clearer statements on the parts of the texts that we know have been commonly used to enable abusers and silence abuse victims, 'Honour your mother and father so that it may go well for you all the days of your life' and similar verses particularly comes to mind as a vague overabused text that could use stricter guidelines to prevent misuse and help people know they will be supported when abuse happens by their church. Not all the changes need to come from behind closed doors, some has to be how the texts are used and taught which I think some denominations will welcome and some with be against, sadly the latter likely being the ones that have had the most issues.
As for the Bible stuff, I don't think the part in Isaiah up to interpretation when we have pretty strong evidence with how the rest of the text is translated that they purposefully mischose the word there along with who Isaiah is talking about. Almah means young women regardless of whether or not she is a virgin just as Alem means young man (used multiple times particularly to describe young David). Betulah means virgin regardless of her age. These words are used repeatedly throughout the Bible (and in many cases with Almah it was very clear she wasn't a virgin like in Songs...) and translated as such so why change it in that one case?
If Isaiah had meant virgin - which he doesn't since he's talking about his own wife and the child she's about to have which happens in the chapter right after that as a sign to King Ahaz and Israel - he would have used Betulah just as it is used everywhere else in the text when referring so. Isaiah's prophecy wasn't about a messiah but is commonly used that way just as the Suffering Servant is even when the text about the suffering servant has many things that aren't part of Jesus's story and specifically says is about Israel. I'm reminded of a Bible scholar who said that within Christianity it all points to Jesus and within Judaism it all points to Israel and how these texts are used and changed over times is something many consider a concern to be aware of and openly discuss while others just ignore it - which is why I asked.
Personally, I found Joseph's reaction odd as a child - in an era when people were desperate for the messiah, surely if a virgin birth was a sign, then he would rejoice rather than freak out. But with the traditional position of Judaism that within every generation there will be potential moshiach but until one is devout enough and inspires the Jewish people back to Torah and rebuilds the Holy Temple those potentials won't become the moshiach and blood isn't required to cleanse sins (all blood sacrifices have a nonblood alternative) and dying with sins doesn't condemn a person so no one needs saved personally but the Jewish people wanted saved politically and collectively until the Christian texts - it makes more sense. He panicked about a virgin birth because it wasn't yet part of the story. How the texts have been changed in usage over time gives a history and look into how ideologies change and are challenged over time and in group debates. I think whether or not Mary should be considered a virgin will remain a debate topic for a long time to come even if Isaiah's young woman isn't part of the discussion (there are some that argue David's line becomes too tainted and that's why among other non-Isaiah related reasons).
I would say the oral tradition which had to be written because the teachers were dying in such numbers it feared it would be lost and then went through the Roman attacks, centuries of various churches burning and calling them heretical, lasting up to modern day 'stands the test of time' more than the written tradition but I don't expect many to take it up nor really recommend it as reading material beyond it's historical value. It fills in some gaps but I wouldn't say it makes any of it more ethical sounding. I mean, the discussion of what should be done to girls and young women who were captured as part of war (tradition is that they were given a month to mourn and after that they would be killed if they didn't turn from their prior ways and dead families) is never going to be a fun topic that encourages belief that this is a good system with a just deity even if one comes from the tradition that wrestling with god is more the purpose than worship. Some things, within all the texts, are really off putting even when in poetic format like bashing infants heads against rocks (Psalms has some messed up imagery in it). Honestly, I get the pull of community and meaning beyond ourselves and feeling connected spiritually, but as much as I've studied it and tried when I was younger I don't get the appeal of the texts as an ethical guide or to build a life on and if everyone can choose what of it to use, I'm not sure the purpose to the texts at all.
