Which quote from Warren is at odds with the bible?
If your pastor is like Rick and cannot call sin, sin, I would look for a new spiritual leader.
“Do you not know that the wicked will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor male prostitutes nor homosexual offenders nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God.” -1 Cor 6:9, NIV

Hebrews 10:24-26 . . . and let us consider how to stimulate one another to love and good deeds not forsaking our own assembling together, as is the habit of some, but encouraging one another; and all the more as you see the day drawing near, for if we go on sinning willfully after receiving the knowledge of the truth, there no longer remains a sacrifice for sins . . .
