Part of why Presbyterians are becoming Catholics is because the Presbyterians have abandoned beauty in their worship service. The Catholics, while perpetuating the abomination of the Mass (and thus re-sacrificing Christ in contradiction to Hebrews), have a stunning worship service. It is lovely. And we human beings are made to respond to beauty like that. When it's missing, we think something's wrong, and rightly so.
