Note: Since Josh's last response to me was aggressive, condescending, and self-righteous, I am declining to engage his posts directly for the time being. But the errors in his posts are worth exposing and resolving, so I will indirectly engage his post.
Josh used a verb ("reconcile") where it looks like an adjective was needed, which caused me to question whether I understood what he is asserting. But I think he is saying that
- the person of the Son being forever the same cannot be harmonized with the claim that Jesus's existence began at the incarnation.
But this is a logical contradiction only if we treat "Jesus" and "the Son" as equivalent referents. If they are not equivalent, if the two are distinguished—as they are in my argument—then there is no contradiction: The person of the Son is eternal, while the in-the-flesh existence of that person—as Jesus of Nazareth—begins in time.
"Did Jesus's existence originate in the incarnation?" Josh asked. Yes, it did—if "Jesus" refers to that human male in first-century Jerusalem. And it does in this argument. When Joseph was thinking about divorcing Mary privately, an angel visited him and said, among other things, "The child within her was conceived by the Holy Spirit. She will give birth to a son and you will name him Jesus." That is when the person of the Son came to exist as man. He already existed as God ("always and forever the same"). But that is when he came to exist as man.
That is simply what "incarnate" means (from the Latin
in carne, to come "in the flesh"). As John wrote, "The Word
became flesh and dwelt among us." He was not eternally flesh, but became flesh and was given the name Jesus. Where was this Jesus prior to that? He did not exist. That human male was conceived and named around 5 BCE. Again, "The person of the Son is eternal, while the in-the-flesh existence of that person—as Jesus of Nazareth—begins in time."
Josh objects that the premise is "foolishness" and "wholly unscriptural." It is neither. Philippians 2:5–11 offers no refutation. Yes, Paul used the name Jesus in reference to the pre-incarnate Son, but that doesn't mean "Jesus of Nazareth" existed prior to 5 BCE. Paul's language is rhetorical and pastoral, not metaphysical. If I were to tell you that Lady Gaga was born in 1986, we both know to whom I am referring but neither of us would interpret it as saying that was her name at birth. (Her name was Stefani Germanotta.) It is a proleptic usage of the name by which we know her, because Lady Gaga did not exist until 20 years later.
This would be a fatally weak analogy, I know, but I hope it's a helpful illustration of "proleptic usage"—for that is what we find in Paul's statement. There was no human male called Jesus of Nazareth prior to the incarnation, but the eternal Son—who would become flesh as Jesus—clearly existed eternally as God, "always and forever the same." Since that's the name by which the Son was revealed in the flesh, whom Paul was writing about, of course Paul used it—proleptically (i.e., the application of a later name to an earlier period in the same person’s existence). He used the name of the incarnate Son when speaking of the pre-incarnate Son. The person is the same; the mode of existence is different, from the Son as God (pre-incarnate glory) to Jesus as both God and man (incarnate humility).
This aligns not only with classical exegesis of Philippians 2 but also with Chalcedonian Christology, unlike the position Josh is arguing.
For the record, I cited the Definition of Chalcedon not to prove that the existence of Jesus began at the incarnation but to prove the Eutychian error of Josh's claim that "there are no distinctions in his two natures."
Josh is correct on that point. But has the Son ever not been Jesus? Yes. There was no Jesus until he came in the flesh. He was the Son, the Word of God, the second person of the Trinity, but not Jesus of Nazareth until "the Word became flesh" (ἐγένετο,
egeneto). That is when Jesus came to be, conceived by the Spirit and given that name. We may say "Jesus was with God" using proleptic language (to identify the eternal Son by the name he bears in history), but it would be incorrect if pressed metaphysically. Before the incarnation, the Son was fully God but not man—therefore not yet Jesus of Nazareth, who was both God and man. Once the Son is incarnate and bears the name Jesus, we can speak of him by either designation—Son or Jesus—and mean the same hypostatic subject.
