But after lots of prayer and study, I realized that Jesus could not have been speaking figuratively when he taught us to eat his flesh and drink his blood. The Jews in his audience would not have been outraged and scandalized by a mere symbol. Besides, if they had misunderstood Jesus to be speaking literally–when he meant his words to be taken figuratively–he could have easily clarified his point. In fact, since many disciples stopped following Jesus because of this teaching (v. 60), he would have been morally obliged to explain the saying in purely symbolic terms.

But he never did. Nor did any Christian, for over one thousand years, ever deny the Real Presence of Christ in the Eucharist. No wonder. So I did what any (Protestant) pastor or seminary professor would do if he wanted to keep his job. I promptly stopped my sermon series on the Gospel of John at the end of chapter 5 and basically skipped over chapter 6 in my classroom lectures.
