The third covenant in this year’s Lenten readings is the central one of Israel’s history: the gift of the law to those God freed from slavery. The ten commandments are one of the chief parts of Luther’s catechism, a core piece of baptismal instruction. They begin with the statement that because God alone has freed us from the powers that oppressed us, we are to let nothing else claim first place in our lives. When Jesus throws the merchants out of the temple, he is defending the worship of God alone and rejecting the ways commerce and profit-making can become our gods.
