I will agree with much of what you have said!
My contention would NOT be the choir vs. non-choir, but rather hymns vs. contemporary songs. Hymns teach, contemporary songs are about getting the congregation into the right "mood". Music is to teach.
My 9 year-old leaves our church singing the traditional hymns because music sticks with you. She is singing the words which are doctrinally orthodox. She is NOT dancing to the beat of a contemporary song (probably because we don't go to a church that has contemporary music).


Grace is not common.
