Copeland's real issue is here: It's all about claiming that Jesus had to be born again so we can be. He also denies that when Jesus cried, "It Is finished!", He was claiming the end of the payment of sin, contrary to a whole slew of Scripture.

This is something he has been teaching long before he became 'wacky for the Jews,' He was wacky for E.W. Kenyon's born-again Jesus heresy long before he had any interest in the Jews or Israel.

If you are interested in a more detailed account of Copeland, Hagin, and Kenyon's heresy, D.R. McConnell's book , A Different Gospel, will describe the reasons why what they say is heretical, and from the Scripture.

This whole 'born-again Jesus ' heresy is actually a deep departure from the Israelite origins of our faith, and a denial that Jesus was the spotless lamb of God who took away the wrath we justly deserved for our sin. Copeland essentially claims it was the Devil who was paid off to leave us alone, and that He (Jesus) took on Satan's nature.

McConnell explains how this is a departure from the Hebrew roots of our faith, and how both the Old and New Testaments describe the atonement as a sacrifice for sin, regarded as innocent and holy, not sin itself.
