To whom do you ascribe authority? In today’s lesson from Exodus, the Israelites challenge Moses’s authority over them because their needs are not being met in the wilderness under his leadership. In Matthew’s gospel, the chief priests question Jesus’s authority as he teaches in the temple. The lesson from Philippians orients disciples to a new way of being—that they take on the mind of Christ. In this passage, Paul casts a vision that every knee will bend and every tongue confess the authority of Jesus as Lord.
