Christian Zionism should be defined by use of quotes from the founders - of dispensationalism. John Darby, C.I. Scofield, Lewis S. Chafer and others said the fundamental starting assumptions of dispensationalism is consistent literalism in interpretation and that God now has two distinct peoples, Israel and the Church. In dispensationalism Israel is always only Old Covenant Israel. Not defining this theology by use of quotes from its founders allows confusion.
Lewis S. Chafer said that dispensationalism has
"...changed the Bible from being a mass of more or less conflicting
writings into a classified and easily assimilated revelation of both
the earthly and heavenly purposes of God, which reach on into eternity
to come.." Lewis. S. Chafer, ‘Dispensationalism,’ Bibliotheca Sacra, 93 (October 1936), 410, 416, 446-447
Dispensationalists try to avoid comparing doctrines of their theology with scripture. Dispensationalism made changes in the doctrines of Romans 2: 28-29, Romans 9: 6-8, Romans 11: 1-5, Romans 11: 17-20, Galatians 3: 3, 16, 26-29, Galatians 4: 24-26 and Hebrews 10: 9,Hebrews Hebrews 13: 20, John 10: 16, Romans 12: 4-5 and Ephesians 4: 4. You can Google "The new John Gill exposition of the entire Bible" and find out the Reformation Protestant meanings for each of the scriptures above and compare those meanings to the doctrines of dispensationalism.
