I have a better impression of liberal denominations than of conservative ones. In general, they take the Bible less literally, some regard none of it as historical. Also, I see liberal denominations not taking themselves as seriously as more conservative branches.
The link was refreshing because the writer suggested decline in his denomination’s numbers might be due, among other things, to a failing of God–that the faith belongs to God, not the denominations and maybe he is not doing it right.
This is a far cry from a common Christian conservative generalization, at least as I perceive it, that when something bad happens it is punishment for one of many sins. That something bad happens and it is not due to the sins of its members is an interesting perspective to say the least.
My own paraphrasing of the link’s author would be, “The faith has been here for a long time and we who follow it have been served well. If the next generation of people do not find anything in the faith that helps them, that’s OK because it belongs to those who are helped by it.”
The author stops short of saying the faith is something people carry around within themselves and does not exist outside the follows’ minds. Perhaps I’m reading my own bias into his writing in saying this, but that’s how I see it.
Ironically, I think the writer’s message of no concern is one that would make the faith attractive to those who are skeptical.
