Can anyone tell me where I can find an article that argues in support of Dual Covenant Theology?

Please let it go. It is not accurate or true. The only Covenant for Jews and Gentiles (all non-Jews) is through Jesus Christ. Because the Jews do not believe this is not reason for Christians to accept that God has a seperate plan for the Jews apart from Jesus Christ. The Old Testament Screams about the sacrifice of Jesus Christ. I dare you to explore. However the Scofield Reference Bible is plaqued with Dual Covenant Theology. I do not recommed you purchase this Bible.
