The Scriptures are so much more than simply what is read or sung in church on Sunday. It is the Word that we read, study, hide in our hearts, and believe.
This has become one of the great and unfortunate changes of our time. There is a movement within the church away from Sunday morning being a part of one's encounter with scripture to the whole of one's encounter with scripture. I will grant that I am generalizing greatly about christians, but there certainly has been a great shift in this direction. I believe as our culture offers more and more things to do, the centrality of the family is broken down (I am talking here about the ability of the family to do things together, respect each other, and teach/learn from one another-not to be mistaken with the argument that homosexuality breaks down the family) that the church has become for many the sole means of spiritual engagement, and in our consumer world can often be viewed as a spiritual gas station...getting one's fill of God for the week. This movement is dangerous indeed and the church's inability to recognize or deal with it for so long has likewise facilitated this problem within the church. Now people try various remedies to fix for example the vast biblical illiteracy that plagues many lutherans today. The most recent attempt is this book of faith initiative which I do not know much about, and have heard mixed feelings about it. I do think it is at least attempting to fix this great and terrible tragedy within our synod.
Although once more I have stranded off topic.

Although perhaps I could bring myself back a bit by arguing that one of the reasons the ELCA is in such struggles today and have so many varying opinions is that one, many possess limited exposure to the bible, meaning they believe it does not speak at all to certain issues or they only are aware of the verses defending one side of the issue. And two, the ELCA has not done an effective effort in creating a unified hermeneutic or thematic vision of the Bible which has caused many different interpretations. While at times I will confess value to the ability to find different meanings from texts, the vastness of difference within our synod has moved us from a rich diversity to a greatly conflicted and divided church on various issues.
And how has the ELCA planned on fixing this? By supporting one or the other side? By giving the church direction in exegesis and interpretation? No, instead it has come out with a social statement that supports such polarizing methods of interpretation and has suggested an unprecedented form of organized chaos in biblical literacy, interpretation, and therefore church practice and belief.

(please note; this is a sarcastic clap).
I think the fact that the current social statement avoids many of the pressing scripture passages that the church has been debating on proves its either unwillingness or inability to offer direction to its people. And all this is "for the sake of unity".

Nevermind how this issue has divided the church, so long as we all call ourselves members of the same synod we are united?
And now I'm ranting and have gone on way too long. I humbly apologize
