Supersessionism comes up again in this week’s reading.   

Much has been made of this “new” covenant being “within them” and “written on their hearts” (Jeremiah 31:33), and some see this as superior to the law written on stone tablets. Indeed, 2 Corinthians 3:3 implies this understanding, but we should go to great lengths to avoid Supersessionism here.
