Nope, I never said he had a problem with a “Real Presence”. I said he had a problem with a “Physical Presence”. The two are distinct.
Then what you really mean is that he had a problem with
material presence, and Catholics don’t believe that the Body of Christ is
materially present anyway, so there is no disagreement. You are evidently confused about what the Catholics are saying, so you probably need to step back and figure out what we are saying before continuing to violently assault a straw man. Note that you said:
Augustine and Calvin are in agreement contrary to Rome that Christ’s body is not physically present in the Eucharist.
In that sense of “physically” (i.e., “materially”), Rome is also in agreement that Christ is not “physically” present in the Eucharist. But what Calvin means by “spiritual presence” is really just an effect on the soul of believers, and that is not
substantial presence (viz., the individual Christ is not present in the Eucharist itself, else Calvin would consider it permissible to adore the Body and Blood). You are wrong to say “Calvin also believed in a ‘Real, substantial Presence.’” He believed in the presence of a real spiritual effect, but not a substantial presence. There’s a difference, and you need to separate four concepts.
(1) Material presence, which no one believes
(2) Substantial presence (i.e., presence of a real substance), which Rome believes and Augustine believed (and probably Luther, albeit incoherently)
(3) Presence of a real spiritual effect (or “spiritual truth”), which Calvin believed to the absolute rejection of (2)
(4) Purely mental presence, in the sense of serving as a “reminder” or “memorial”
Dave Armstrong’s point was that even Kelly, Schaff, and Pelikan were forced to admit that both (2) and (3) were present in Augustine (as they are in Catholicism), and that point stands even if Dave mistakenly believed that a few passages about (3) were about (2). In their conclusions, each of these authors admits that Augustine also believed (2),
contra Calvin, and they were forced to then argue that Augustine was somehow inconsistent in holding both (2) and (3). But that is practically an impossible task; one has to accept Calvin’s mucked-up metaphysics of the creature/Creator distinction to hold that (2) and (3) conflict with one another.
I really think you need to go back to the drawing board on this one. You seem to have managed to prove conclusively that Calvin CANNOT be reconciled with Augustine, and but for your misunderstanding, it is plain that the Catholic view CAN. In other words, you’ve proved exactly the opposite of what you set out to show.
