pretty interesting polls. I was raised in an Episcopalian Church. My mom taught sunday school and I went to services on sundays. I enjoyed my time there but mostly stopped going when I got in to my teenage years. Even then, 20+ years ago the Rector (damn near killed her) of the church was a gay man. Everyone knew he was gay but no one really cared, so it was surprising to me as I got older to see how gays were viewed by other religions and churches across the country. My mom eventually left the church because she didn't get along with some of the newer people in charge after the rector moved on to another church.
I find the polls interesting because I've always viewed a church's strength by the community it keeps. Years ago it served an important purpose because it gave people a reason to congregate. Everyone has varying levels of how strictly they adhere to the "teachings" of each religion, but at the core I still believe it's greatest strength is the ability to bring people together. Modern times now have a near unlimited amount of opportunities for people to "congregate" and many churches are being left behind.
I view "religion" as a personal journey, while the "church" is for the congregation. People don't need churches the way they use to for practicing their religion.
Of course churches do not have to change their ways, however it's clear that many will have to change their ways a bit if they want to keep people interested.
