I do have a problem with that first one: "Rick Warren has publicly said that he will not preach against homosexuality and abortion as it may offend some in his congregation."
We are not to be pleasers of men, at least not to the point of putting their point of view before Gods.
If he wasn't, he couldn't consult Synagogue 3000, using purpose driven principles, helping them to become more hip in order to increase numbers.
The Apostle Paul enetered synagogues and reasoned with them from Scripture proving that Jesus was ressurected and the Christ.
The Apostle Paul preached the Gospel and Biblical doctrine to Greeks and idol-worshippers, telling them to repent.
In contrast, Rick Warren enters the synagogue and assists their teachers in discovering new ways to be relevant and increase numbers (Thus, Yom Kippur Yoga and the like).
Also in contrast, Rick Warren doesn't address false teachers with the Gospel, nor Biblical doctrine, nor the message of repentance...he endorses them, uses them in his materials, and implements their unbiblical practices (yoga, contemplative prayer, feel good messages, labyrinths, mysticism, and etc.)
