This is an interesting discussion on Issues, Etc. about the Lord's Supper, in which several pastors contrast the Lutheran and Reformed views of it. If you are interested in hearing the differences, or if you are only familiar with the symbolic view of modern evangelicalism and/or the transubstantiation view of the Roman Catholic church, this would be a great program for you to listen to. Why all this theology? I will quote my husband:
Know what you believe and why you believe it.
