The latest Liturgical Titbit:
Lutherans, unlike everyone else it seems, stand to pray and sit to sing. Why?
The reason for sitting for hymns is almost certainly entirely prosaic. Lutheran hymns were traditionally long, and often sung very slowly. If hymns last 20 minutes or more, sitting down is quite sensible. Since that’s rarely an issue these days, perhaps this is a tradition we would do well to reconsider.
As for prayer, the Bible knows three postures for prayer: standing, kneeling and prostration. All of these are ways of recognising the fact that when we pray we are in God’s presence.
Just as we stand in the presence of a judge or a monarch, we stand in the presence of God—unless of course we kneel or prostrate ourselves. These latter postures are expressions of humility and penitence, of our dependence on God and our unworthiness. This is why kneeling for prayers of penitence (such as the Confession) is particularly appropriate. Again, perhaps this is something for us to reconsider.
