Why are mainline Protestant denominations losing members? [View All]

[Celeborn Skywalker]

I just finished reading an article where it states that membership in the traditional, mainline denominations has seen significant decline since the 1970's. The article also stated that membership is down in the Catholic Church.

Why is this? Is it because of the evangelical megachurches? If this is the reason, why are these fundamentalist churches so attractive to people? Or is it some other reason? In my opinion, the traditional denominations are the among the last holdouts of reasonable, thoughtful, Christianity in this country and it is a shame they are losing so many members.
