I grew up in the Lutheran church, and was confirmed and baptized there. In my case in that order, as while as long as I can remember I've believed in God, during my confirmation classes it was my mom sending me to do it, whereas the latter was a couple of years later and was something instigated by me. The former must've been in 8th grade, as I recall going on a winter retreat for confirmation while my leg was in a cast, and one time when everyone went off to play in the snow, a kind soul in my class stayed behind and played chess with me. She was no good at it, but she was angel for doing it. The latter must've been 10th or 11th grade, because it was before I started driving, and working my first non- paper route job. Some nerdy kid in jr. high mentioned to me that he had read the whole New Testament once, and I was inspired to and planned to do the same, and prolly did that around 9th or 10th, between those two events.
Anyways, that all predated the formation of the Evangelical Lutheran Church in America, and having heard in college how this was veering Left and (not so coincidentally) away from the Bible, I was disappointed to learn that my mom and I's little neighborhood church had affiliated itself with them. Which is when I began to try out some other kinds of churches, including the more conservative-leaning (actually a bit too much for me, I found out!) Lutheran Church - Missouri Synod, and ultimately landing in an affiliate of the Biblically-serious but otherwise quite laid back Calvary Chapel, uh, non-denominational "denomination".
The ELCA first started pushing the envelope when they began ordaining female ministers. IIRC, there's something in the Bible about women should not be teachers over men. Might be part of the preservation of God's order, and to mirror and reinforce the analogous order in heaven. I've gotten the impression that in strength and lack of ambiguity it is more serious than "women should wear hats in church", but less than a "God hates it when a woman is put in a doctrinal leadership position over other than children (of either gender) and fellow women". I.e. proper reverance would indicate erring on the side of respecting God's word, and the church chose not to. Which is never a good sign.
At some point they okayed celibate homosexuals for becoming pastors. Possibly surprising to some and disappointing to others, I'm okay with that move. The Religious Right, of which I include myself, characteristically tends to overplay the sin of homosexual activity. To a Perfect Being, it is no more of a stain on one's soul than a heterosexual indulging in lustful thoughts. (Notice I didn't say merely "having", as that is temptation placed by the Enemy, but running with it is one's own responsibility.) It's an important distincton that it is not a sin to be a homosexual, it is a sin to engage in that type of activity. The Bible only says God hates the activity. But it is not the case that "God hates fags", as Jesus died for all, and before Him everyone was unworthy. By committing to celebacy (or marrying the opposite sex and keeping sexual relations within that framework), the homosexual is as "flawed but trying" as a straight person.
But now they've green-lighted practicing homosexuals for the clergy. Now I'm "a practicing sinner", for sure, but I recognize my bouts of disobediance as being wrong, and try to avoid it, not embrace it. The implication there is "practicing homosexuals" plus "being fine with that".
To this end the church has draped it in positive-sounding window dressing: "publicly accountable, lifelong, monogamous, same-gender relationships". But that's proverbially like putting a gold ring in a pig's nose. Monogamy is only holy in the context of (heterosexual) marriage. If I shack up with a gal, I can be as monogamous as I want, but it's still extra-marital sex. And attaching "lifelong" to a prohibited activity only makes it worse, not better. Better to be an occasional bank robber who struggles with it than a committed, lifelong one. So again, "lifelong" is only admirable if what that commitment to is deemed admirable. And like these other words included for the purposes of deceit (a sin), "publicly accountable" sounds good, but is meaningless in the context of Christianity, as that's all about accountability to God. In fact what it does do is serve to indicate where and that the focus of the mainstream Lutheran church in America is now about pleasing man and the world and less so God.
