Jenkins seems anti-West to me in a lot of his views. It is NOT necessary for immigrants to be the factor in spritual re-vitalization...what IS needed is the Holy Spirit.
He leaves out this very large factor in many of his arguments while seeming to go along with the notion that the syncretism of much Asian and Latin "christianity" is OK.
Jenkins seems much more of a sociologist to me (and I betcha he's a liberal one at that) than one that should be consulted on theological matters.
My guess would be that over 95% of the people who have earned PhDs in sociology from American universities within the last twenty years are committed leftists.
