I suggest that for the "communion hymns," ie., the hymns sung by the congregation during the Holy Communion at Mass, that it would be appropriate and make the most sense to sing hymns that are actually communion hymns, ie., hymns about and in praise of the Blessed Sacrament. Seems logical enough. And it's not as though we suffer from a lack of such hymns in our language. There is even a whole section of hymns in Lutheran Service Book devoted specifically to this subject. Several of them are actually worthy of being used in the Church.
And yet, in my experience in Lutheran churches it is virtually never the case that the hymns during Communion are reserved for singing about the venerable Eucharist. It seems far more common for the communion time to be peppered with hymns directed or loosely about the sermon theme of the day, or hymns of praise, or hymns on the doctrine of justification, or a combination of the above. Pastors who are slightly more eucharistically conscious will throw in maybe one eucharistic hymn, maybe two, usually just one. At my own parish it seems to be usually the second hymn at communion. I attended Mass recently at another church where there was not one eucharistic hymn; all the hymns during Communion dealt with the theme of the day. This is not to pick on any one congregation or pastor, for it seems to be a matter, rather, of the current culture of our church.
I challenge the reader, both lay and clergy, to take this as an opportunity to think on this issue. And then think some more. I know it is longstanding custom to sing a very limited number of eucharistic hymns, if any, during the celebration of the Eucharist. But ponder what is going on. Meditate upon the holy mystery that is taking place during that time. The tradition of the Church has given us some great hymns for this purpose. If we end up singing them more often than we have been accustomed to singing them, the awful consequence will be that we will actually get to know them better. They will come to occupy a deeper place in our hearts. And they will prove to be a great aid to our devotion and worship. They would help make of that moment more than the utilitarian "distribution" time, for we might actually, as a church, come to see that time as a Holy Communion with Christ our Immanuel, our Eucharistic Lord.
