Referred to in Jewish literature as “That Man”, so that they didn’t have to write out his name, or alternatively “Yeshu” (.י.ש.ו)- which stands for “May his name be forever erased and forgotten”, Jesus has been avoided in polite conversation among in Jewish communities for most of the last two millennia. Reviled as a traitor and heretic, and blamed for the bloody persecution and murder of Jews at the hands of the church for centuries, Yeshua was considered straight out dangerous.
Supersessionism, also called replacement theology or fulfillment theology, is a theological doctrine held by some on the current status of the church in relation to the Jewish people and Judaism. It holds that the Christian Church has succeeded the Israelites as the definitive people of God or that the New Covenant has replaced or superseded the Mosaic covenant. Paul clearly contradicts this when in Romans 11 he writes “Did God reject his people? By no means! I am an Israelite myself, a descendant of Abraham, from the tribe of Benjamin. God did not reject his people, whom he foreknew.”
The most significant of all God’s trustworthy promises was the promise that He would send His Son, the Messiah and Savior, into the world. In 2 Corinthians 1:20, Paul wrote, “For all the promises of God find their Yes in him. That is why it is through him that we utter our Amen to God for his glory.”
