“Remember the Sabbath day, and keep it holy… Wass ist das?... We are to fear and love God, so that we do not despise preaching or God’s word, but instead keep that word holy and gladly hear and learn it.”
Notice what Luther does, he moves Sabbath from chronos to logos, from time to word. He de-centers Sabbath praxis into theological doxis, action into theology/thought.
One of my understandings of Sabbath is that it is a time of rest. Now, resting in God’s word is good, but I genuinely think humans are less neurotic and more whole/holy when they have a day off. In short Sabbath is about more than preaching and Word.
When a shift like this occurs it leaves room for people to abuse themselves and others. “Sure I work 90 hours a week, but I make sure to read my bible before I go to bed.” “I pay my millworkers almost nothing and they live in squalor, but on the plus side I’ve built a Methodist Church for them.”
I’m respecting God’s word, but not the rest that God’s word recommends.
