Replacement Theology is also known as Supersessionism and Fulfillment Theology. No matter the name, it is a dangerous and false doctrine. So much so that it was denounced by both the Protestant and Catholic churches after the Holocaust.
There are many beliefs that make up Replacement Theology but the three main premises are:
Jews are no longer God’s chosen people, the Church has replaced them.
After Pentecost, whenever the NT mentions “Israel” it’s actually referring to the Church. Therefore, the Church is Spiritual Israel and the “Jews” are Gentile believers who are “inner Jews.”
The Mosaic Covenant was replaced by the New Covenant and the Abrahamic Covenant completely abolished. Therefore, the New Covenant through Jesus supersedes (thus, Supersessionism) or replaces the old covenant which was made exclusively with the Jews.
Replacement Theology has:
Misinterpreted God as a fickle God who breaks His own promises and backtracks on what He has established.
It paints God as having made an everlasting covenant (Genesis 17:7-14 & Exodus 19-24) with Abraham and Moses only to break them in the New Testament, despite promising that His Word would come to pass (Isaiah 40:8). If God is the same yesterday, today, and forever (Hebrews 13:8) then why would He change His mind about Israel?
Created anti-semitism
It’s easy to see how replacement theology has caused anti-semitism. It was in the minds of people long before Martin Luther published his hateful proclamations against Jews which influenced Nazi philosophy.
Some of the comments of the church fathers show why this philosophy is so dangerous.
Hippolytus of Rome said that the Jews had been darkened in the eyes of their souls, “with a darkness utter and everlasting.” And declared that Jews were destined to be, “slaves to the nations, not for four hundred years as in Egypt, nor seventy as in Babylon, but always.”
John Chrysostom said, “Jews are inveterate murderers possessed by the Devil. Their debauchery and drunkenness gives them the manners of a pig… This is why I hate the Jews.”
Ambrose of Milan said, “The Jews are the most worthless of all men. They are lecherous, greedy, rapacious. They are perfidious murderers of Christ. They worship the Devil. Their religion is a sickness. The Jews are the odious assassins of Christ, and for killing God there is no expiation possible, no indulgence or pardon. Christians may never cease vengeance, and the Jew must live in servitude forever. God always hated the Jews. It is essential that all Christians hate them.”
"Epistle of Barnabas" Chapter 4vs 6-7 (between 130A.D. and 138 A.D.)
Take heed to yourselves and be not like some piling up you sins and saying that the covenant is theirs as well as ours. It is ours, but they lost it completely just after Moses received it.
Justin Martyr- The custom of circumcising the flesh, handed down from Abraham, was given to you as a distinguishing mark...
The purpose of this was that you and only you might suffer the afflictions that are now justly yours; that only your land be desolated, and you cities ruined by fire, that the fruits of you land be eaten by strangers before your very eyes; that not one of you be permitted to enter your city of Jerusalem
Peter the Venerable- Truly I doubt whether a Jew can be really human… I lead out from its den a monstrous animal, and show it as a laughing stock in the amphitheater of the world, in the sight of all the people. I bring thee forward, thou Jew, thou brute beast, in the sight of all men.
John Calvin - Their [the Jews] rotten and unbending stiffneckedness deserves that they be oppressed unendingly and without measure or end and that they die in their misery without the pity of anyone.
Martin Luther- First, their synagogues should be set on fire, and whatever does not burn up should be covered or spread over with dirt so that no one may ever be able to see a cinder or stone of it. And this ought to be done for the honor of God and of Christianity in order that God may see that we are Christians, and that we have not wittingly tolerated or approved of such public lying, cursing, and blaspheming of His Son and His Christians.
Secondly, their homes should likewise be broken down and destroyed. For they perpetrate the same things there that they do in their synagogues.
Thirdly, they should be deprived of their prayer-books and Talmuds in which such idolatry, lies, cursing, and blasphemy are taught.
Fourthly, their rabbis must be forbidden under threat of death to teach any more...
Fifthly, passport and traveling privileges should be absolutely forbidden to the Jews. For they have no business in the rural districts since they are not nobles, nor officials, nor merchants, nor the like. Let them stay at home..
You ought not, you cannot protect them, unless in the eyes of God you want to share all their abomination..
Caused Jews to loath Christianity
Because of the atrocious sentiments and statements against the Jews, it has made them reject the Gospel and caused difficulties with Jewish evangelism.
So you ask me why I have always stood here or in person against Replacement Theology. THIS is the reason! This is where the doctrine comes from. Do these comments seem Christlike to you??!! I will ALWAYS stand against Replacement Theology. Maybe someone will join me now they see it's roots which led all the way to the Holocaust.
