My friend Jim posted an interesting article by a Roman Catholic Father today, and I commented on it. Below is what I wrote on Jim's blog.
The issue about inter-communion for me as a Lutheran is not so much a problem of being excluded - last year I attended a RC church with a friend of mine, and went up to the priest and received a blessing rather than holy communion, which was wonderful - I receive communion weekly at my own church, so I don't NEED to receive it elsewhere. We have a good relationship with our neighboring RC church, and work together in many ways.
It is really a difference in eccelesiology, as Fr. Tucker's statement reveals. As a Lutheran pastor (of the ELCA, not the LC-MS), I give communion to every Christian who wishes to receive it. For ME to deny someone communion because they are not a part of my church body, because they do not fit into my hierarchical structure, would be an insult to the Holy Spirit, who blows wherever it wills and creates faith in the hearts of many people who do not share my denomination. I understand the difference between a Lutheran and RC ecclesiology, and I am not complaining about being excluded, just offering a different ecclesiology.
I am also not so sure that a multitude of denominations is an evil. Let me quote from the Augsburg Confession VII: "It is enough for the true unity of the church to agree concerning the teaching of the gospel and the administration of the sacraments. It is not necessary that human traditions, rites, or ceremonies instituted by human beings be alike everywhere." That is the difference in ecclesiology right there. So, there are Lutherans, Methodists, Catholics, Episcopalians, Baptists, Orthodox and more. As long as we have the same gospel, and the same sacraments, that diversity can be a gift to the world.
I also disagree with the image of the RC church as the mother church, and all other churches (including the Orthodox church!) as her rebellious children. But again, it's a difference of ecclesiology, and the question is, which ecclesiology is closer to the gospel truth.
