Exegeting the verse grammatically really doesn't make much of a difference.
Matthew 11:23 ....For if the miracles that
were performed in you
had been performed in Sodom, it would have remained to this day.
a). the "were" is in reference to Capernaum.
b). the "had been" is in reference to Sodom.
The "were" is the correct starting point: "If miracles were performed in Sodom." Why? For the simple fact that the word "were" is carried over and continued into another. Because Jesus is talking about "the miracles that were" (or those recent past miraculous events in Capernaum) being carried over and superimposed into Sodom, which is the basis for the hypothetical and "if" is justified by the verb. For instance, Jesus lived in Capernaum and a fulfilled prophecy (Matthew 4:12-17), healing of Peter’s mother-in-law (Matthew 8:14-15), and healing of the blind and mute (Matthew 9:27-34). Of course, so many other miracles happen in Capernaum, but it's a brief idea leading up to Matthew 11:23. So, the idea is not just Jesus' miracles themselves that is carried over, but also, the one who is performing the miracles or Jesus himself is added into the equation. Since Jesus is performing the miracles, and those same type of miracles that "were" is carried over and to be asserted into Sodom.
Semantic and hard to articulate. The "if" in conditionals doesn't always mean hypothetical but also can be actual. Remember that Jesus' statement is only hypothetical. It's like you are trying to overlap the hypothetical conclusion with the actual conclusion. Then you projected that on me as if I'm committing a fallacy. This is what I mean about you not distinguishing between "hypothetical" and "actual." My conclusion in post 16 is (F, F, T),
which isn't based on hypothetical conclusion resulting in a fallacy, but rather, on the actual conclusion of what we already know about the real-world concerning Sodom. Did you understand that? I've underlined for you. And that is why you arrived at a logical fallacy of Denying the Antecedent. Then you think it's falsified because you think there is no truth value to be obtained in the hypothetical. For the most part I agree that there is no truth value can be obtained in the hypothetical. But we do know that truth value is obtained in the actual world.
Actual World:
a). Did the same-type miracles performed in Sodom? No.
b). Did Sodom repent and still existing to this day? No.
This was explained to you already.
Post 38: The logical form of a conditional doesn't depend on something is actually true or actually false. No matter how absurd, like "If a banana tree is planted in the air, then it doesn't require soil." We know in the real actual world that is not the case. The logical form of a conditional itself isn't invalid. No matter how ridiculous a statement might be. The idea can be absurd and irrational, but the logical form itself is true.
You are thinking "Why P being false and Q being false, then the whole conditional isn't false but true?" That's your head scratcher? Because a logical conditional isn't a logical conjunction. The logic behind the logical form is false, but the logical form itself valid but true. For example, "If earth worms grow wings, then intelligent designer is the cause." That is hypothetical and doesn't make sense in the actual world. After all, it's false that earth worms could grow wings and false that it's caused by an intelligent designer. But, nevertheless, it's a TRUE valid conditional (F, F, T). Or again, “If miracles were performed in Sodom, then Sodom would have remained to this day.” That is hypothetical and doesn't make sense in the actual world. After all, it's false that miracles performed in Sodom and false that Sodom is still existing. But, nevertheless, it's a TRUE valid conditional (F, F, T).
I have no idea what you are trying to figure out. It could be that you simply lack knowledge in basic Propositional Logic and never actually studied it. Besides a few discussions here and there doesn't really qualify. And you want to express what you want to say, but you lack that clarification and articulation. Well, me too, and it takes years to practice it. So, I'm sure, eventually, I will be able to zero-in what you are trying to suggest.
