This Pew Research Center survey questioned "Lutherans in the Mainline Tradition." I believe the Evangelical Lutheran Church in America (ELCA) is the only Lutheran denomination considered to be in the mainline tradition.
There are two charts below. Firstly, people in the ELCA were asked "who they look to...most for guidance on right and wrong."
In the second chart posted here, people in the ELCA were asked about their belief in absolute standards for right and wrong.
Again we see the lack of Biblical literacy, knowledge and reverance of ELCA members, due, for the most part, to a low regard for Scripture and its truth being preached in their ELCA congregations. Seventy percent of those surveyed said that "right or wrong depends on the situation." No wonder the ELCA supports the killing of unborn children, celebrates homosexuality, ordains transsexuals, makes antisemitic policies, allows goddess worship, rewrites the Bible to their way of thinking and does not instruct their missionaries to lead people to Christ. Many of the people and pastors do not know the Bible, have decided it has little authority in their lives or have turned their backs on it.
It's time to find a Bible-believing church to attend, my friends.
