Americans not losing their religion, but changing it often
A few observations:
1 - "I began to see there were some things I wasn't able to get on board with fully. I don't like the traditional Episcopalian focus on the afterlife."
Notice the criteria for this change; not I investigated or studied the Bible and came to a different conclusion, but rather..."I didn't like it." as if it was Butter Pecan ice cream vs. Mocha Almond Fudge. Truth is not a flavor of ice cream. But many people treat religion like it is.
2 - "More than four in 10 American adults are no longer members of the religion they were brought up in, while about one in 10 changed religion, then went back to the one they left, the study found. Just under five in 10 -- 47 percent -- have never changed faith."
Change is not necessarily bad of course, but the reasons are what is important here. And if it is simply people being too busy and drifiting or not liking something...those aren't good foundations to build a worldview and way of life on.
Christianity works becasue it is true; it is not true because it works.
