Doctrine in general is downplayed.
We are too much into Church growth bending over backwards to give the visiting adult kiddies a fun and 'relevant' time.
Don't bring up sin and judgment and other icky things as that will scare off the people (interpreted as $$).
Don't bring up specific sins as that is so judgmental and not politically correct.
Keep the pablum running with videos and clown acts that'll keep their attention and the fun seekers coming.
Don't dive into doctrinal issues, that is just something they fought over in the 17th century.
I'm OK, you're OK unless you fail to smile.
I think this is the gist of the OP, not what is the 'perfect doctrine'.
