I don't know anything about Sean, but this was an observation that I thought was absolutely right on the mark.
Bob Dylan converted to a sort of "Jesus People" Evangelical Christianity way back when, and they were notorious for expecting insane levels of perfection (and even prissiness) from their members. Also, this group sure wasn't exactly up on the creative world, and I don't think Dylan saw his future as singing that gawd-awful "Christian Rock."
Many of the "Jesus People" either washed out or became Orthodox or Catholic if they wanted to be in contact with the larger world, but I don't see Bob Dylan as having either the time or the interest to consider this.
He's a leftist, and that will never change, but I think he's still a Christian, even if he's not part of a church.
What a crock, no the Evangelical movement and Jesus Freaks did not become Catholics and Orthodox, they stayed Evangelicals.
As far as Dylan's politics, we don't know, the only candidate favorite that he has named was Goldwater.
Your premise is wrong. Bob was taught in the Vineyard Fellowship. Flinging out the term "Jesus people" and attaching your own personal definition to it is a bit disingenuous. I expect better from you.
