You do know, don't you, that the only song that's allowed to be shortened in church these days is a hymn, right? But honestly, I'm with you.
Hymns in protestant churches were always intended to be devices not only for praise, but also for teaching sound doctrine. Read the lyrics to some of the very old hymns and you will find just that.
Unfortunately in our postmodern culture, truth is supplanted by emotions, so these songs no longer appeal to many people my age (20-35). The appeal to have bigger churches (which means more $$) has caused leadership to abandon doctrine for emotionalism (what Micahel Horton refers to as “moralistic, therapeutic self-held deism”). Jesus, on the other hand, intentionally made statements of truth that caused nominal followers to fall away (”eat my flesh... drink my blood”). But you can’t operate a business on such principles, and your pastor sure as heck couldn’t afford his BMW if he did. Church is for true believers, but there are so few of them that a churchianity business has to appeal to many unbelievers to make money.
