I'm struggling to fully understand the Catholic emphasis on communion; it's one of the things that divides the capital-C Church into Catholic and Protestant camps.
It's not the only one. Veneration of Mary, having saints intercede with you in prayer (that's a more accurate description that "praying to saints") and (rarely used by modern popes) papal infallibility are the classic ones that you hear evangelical critics trot out, more-so than transubstantiation.
However, I can wrap my mind around designating one guy as head honcho and having him clarifying doctrine when the need arises; it runs counter to our American/Anglospherian democratic impulse, but letting doctrine be put to a vote is even more dangerous as exhibited by some of our more liberal denominations.
I can also wrap my mind around having dead believers alive in Heaven willing to put their two cents in for you with God; that seems more understandable than putting all folks into a spiritual suspended animation until Judgement Day.
I also can intellectually understand the idea that Jesus is in the communion elements in some mystical way that runs askew to secular logic. However, there seems to be something far more than that going on with the Eucharist. As I'm envisioning it, Communion is not just sharing something with your fellow parishioners, but having a spiritually tangible presence of God (the Real Presence is the common shorthand for that) that connects the partaker with God and His Church more than just a modern docudrama of the Upper Room.
It's important enough where it's part of every service and taken to the folks unable to make it to church. Some Protestant churches (Anglicans and Campbellites come to mind as well as a number of Vineyard churches) do communion on a weekly basis, but there doesn't seem to be quite the focus on communion as there is with the Catholics.
I'll ask the Catholic members of the Peanut Gallery... what am I missing? I'm sensing that there is something more caught than taught, more in the realm of a hands-on Holy Spirit than in some catechism, but there also might be some theology that this low-church evangelical doesn't quite grok.
