OK, this is round one of "Name that legalist: a game the whole church can play."
Who wrote this?
Therefore it is not without reason that the Old Testament command was to write the Ten Commandments on every wall and corner, and even on garments. Not that we are to have them there only for display, as the Jews did, but we are to keep them incessantly before our eyes and constantly in our memory and to practice them in all our works and ways.Don't consult google. Have a guess. Here are the usual suspects:
Each of us is to make them a matter of daily practice in all our circumstances, in all activities and dealings, as if they were written everywhere we look, even wherever we go or wherever we stand.
Thus, both for ourselves at home and abroad among our neighbors, we will find occasion enough to practice the Ten Commandments, an no one need search far for them.
The answer, of course, was d) Luther
Well done to Messrs Walker and Bennett. Luther of course was no legalist, unless you count saying anything positive about God's law and the Christian life as a form of legalism.
