The former must be read spiritually, and the latter is impossible, because Augustine says "Why ready teeth and stomach? Believe and you have eaten already." Thus faith precedes any possible physical eating, and therefore can't refer to the eucharist at all. You say this yourself in your other post, writing "he is not speaking about the Eucharist," not realizing that such an admission confirms my position. But note how you tried to claim that Augustine is not talking about eating Christ, as if he was making some general comment about food, and not giving instructions on how to eat Christ, thus you wrap yourself up in all sorts of trouble, because, quite clearly, Augustine is talking about eating and drinking Christ's body and blood.
But this is incompatible with the view that Christ is eaten through the Eucharist, confirmed partly even out of your own mouth. If Augustine is talking about Christ's body and blood, you can't claim that eating the eucharist is necessary to eat Christ. These things must be entirely exclusive, otherwise you contradict Augustine's words: "Believe and you have eaten already."
Thus my explanation of the difference between Augustine's teachings on the eucharist and his teachings on eating Christ through faith remain unmolested and supported by the other quotations I already made. I see no reason to accept it because not only does reading more of Augustine than the quote "believe and you have eaten already" show more than a passing importance to the Eucharist,
Well, if we read MORE of Augustine, my position only gets stronger. I've only shown you a small fraction of the quotations I have. Do you want the rest?
I have the rest and have posted its entirety repeatedly, which you have never done. I rest on that. True context. All of what he said (on John). All of it.
Again, I don’t recognize your authority to define Augustine’s writings.
