Don't bother. Warren's positions are well known and been refuted from within other representatives of Evangelical Christianity. This document is probably one of the more well known:
RICK WARREN'S GLOBAL P.E.A.C.E. PLAN vs. SCRIPTURAL TEACHINGS ON PEACE
It offers some insights into what Rick Warren is up to.
I am affiliated with a pretty wide body of Christians who have refuted Rick Warren and everything he teaches and promotes. That Warren would meet with a known terrorist supporting leader like Assad, thereby undermining American foreign policy, further proves the wisdom of our church leadership's decision.
Rick Warren is "off the reservation," if not completely off the chain, and I personally reject any association with him and his supporters. In a world of bio/chem and nuclear weapons "in the wild" and the stated goals and objectives of global Islamism, sitting down and "dialoguing" with the likes of Assad and Ahmadinejad is not only ludicrous, it shows a complete lack of understanding and comprehension of what we are facing in the Middle East, Israel and America combined.
Murderers only understand force. Bush and Rumsfeld understand that. But the majority of the American electorate just pulled their plug.
The Bible teaches specifically that the Jewish nation is going to face a global isolation some time in the future. The Jews may not like it; supporters of Israel, whatever their stripe might not like it, but the reasons why are clear. As the children of Israel faced Pharaoh, with their back to the Red Sea, they had only One to turn to. To trust wholly in G-d and not in men. Thus, Israel will be okay.
Up to this point, the national Evangelical Christian community in America and their vocal and much vaunted support of the Nation of Israel has been much published. With Warren and his being duped by the Syrians into becoming a propaganda stooge like this, his already shaky credibility will be further eroded, and that support will grow a little smaller.
But not from me.
