John 3:6 – Jesus often used the comparison of “spirit versus flesh” to teach about the necessity of possessing supernatural faith versus a natural understanding. In Mark 14:38 Jesus also uses the “spirit/flesh” comparison. The spirit is willing but the flesh is weak. We must go beyond the natural to understand the supernatural. In 1 Cor. 2:14,3:3; Rom 8:5; and Gal. 5:17, Paul also uses the “spirit/flesh” comparison to teach that unspiritual people are not receiving the gift of faith. They are still “in the flesh.”
John 6:63 – Protestants often argue that Jesus’ use of the phrase “the spirit gives life” shows that Jesus was only speaking symbolically. However, Protestants must explain why
there is not one place in Scripture where “spirit” means “symbolic.” As we have seen, the use of “spirit” relates to supernatural faith. What words are spirit and life? The words that we must eat Jesus’ flesh and drink His blood, or we have no life in us.
John 6:66-67 – many disciples leave Jesus, rejecting this literal interpretation that we must eat His flesh and drink His blood. At this point, these disciples really thought Jesus had lost His mind. If they were wrong about the literal interpretation, why wouldn’t Jesus, the Great Teacher, have corrected them? Why didn’t Jesus say, “Hey, come back here, I was only speaking symbolically!”? Because they understood correctly.
Mark 4:34 – Jesus always explained to His disciples the real meanings of His teachings. He never would have let them go away with a false impression, most especially in regard to a question about eternal salvation.
John 6:37 – Jesus says He would not drive those away from Him. They understood Him correctly but would not believe.
John 3:5,11; Matt. 16:11-12 – here are some examples of Jesus correcting wrong impressions of His teaching. In the Eucharistic discourse, Jesus does not correct the scandalized disciples.
