..I love hearing things like this--God bless you and your church...
See my post about Jim Wallis above. Also I'm sure Tommydale can give you some ideas, or Gamecock, or Alex Murphy.
There's a huge delusion going on in the church at large. Sometimes people can't find a church to attend because they've all gone liberal/watered down.
I personally attribute it to stuff like the vain philosophy of men, "Church Growth" which is false teaching. It bascially ends up being "do what it takes to bring in a crowd", thereby diluting the saltiness of the 'salt of the earth' -- and who can make it salty again?
