When did Israel stop believing that Jesus was the Christ?

Les teaches that Israel was no longer going to believe Jesus was the Christ after the original day of Pentecost, shortly before A.D. 70. At that time God sent them back into the mainstream of humanity, not as evangelists but as a wandering nation steeped in spiritual blindness and unbelief. Les marks this as the transition to something totally different: the outcalling of the Body of Christ, the Church Age. This is a Pauline revelation, distinct from Old Testament prophecy and the nation of Israel, so it must be taken out of the way before God resumes His program with Israel for the final seven years—divided 3½ and 3½—and the appearance of the Antichrist. Les notes that all these events led up to the crucifixion of Christ.
