That's cool.
I just mean to say that weekly communion is a Lutheran tradition, and that it's abandonment came through Pietism and union with Reformed traditions. It's contemporary introduction is a reintroduction of a traditionally Lutheran practice, and not an adoption of a Catholic one.
And I also mean to say that wereas everything else is somewhat accidental, the inclusion of Holy Communion in the Sunday morning liturgy is, I think, essential. The abandonment of weekly communion in the Lutheran churches reflects, I believe, a loss in lay understanding of the magnitude of the Eucharistic presence of Christ and the influx of Pietist emphasis on preaching (particurally technique-oriented preaching). It reflects a loss of of appreciation of God's self-giving to man in favor of anthropocentric self-help culture and individual piety, and the exchange of God's self-giving to man in favor of man's attempt to do something for God. In short, it reflects a loss of the connection between the gospel as an abstract doctrine and the gospel as practiced and performed on us by God in our liturgies.
