Its systematic theology is internally consistent; amazingly consistent given three thousand years across 66 books and dozens of authors. It’s the cherry picking and overemphas that gets one into trouble
>Is there something new or relevant you’re making a case for?
New? Not, not really. It's not at all new that the official position of the church ("Jesus is entirely mortal and entirely divine") is inherently self-contradictory. I mean, what the hell. If I didn't know any better I'd think an atheist came up with it to troll early Christians. Try saying something similar about literally anything else. "The contents of this glass are simultaneously entirely water and entirely mercury." It says nothing good of either the followers or the clergy that that nonsense has been accepted for so long.
It's not inherently self-contradictory for us to say "Jesus revealed Himself as the Son of God and the Son of Man ... how can we properly speak about that?" https://www.newadvent.org/summa/4002.htm#article2 - now that requires a lot of extra distinctions that we don't normally think about when thinking about being and essence, but it's certainly not impossible.
"Mr. Archibald Potterfarthing is at the same time the Chair of the Committee and at the same time its most senior ranking member". Accidents, naturally, but co-existing in the same space-of-being. It turns out that "person" and "nature" are distinct (who knew?) and that it is possible for there to be one person with two natures just as well as there can be one person with two titles. But that presumes you believe the authority of the one who told you this - if not, it's useless to talk about it, because why would you ever need to distinguish person and nature unless you had encountered the reality of Christ? Nothing else we have encountered in the universe has (as far as we are aware) two natures. But nothing else behaves like a singularity either - uniqueness is not a proof of non-existence.
Do you have similar concerns about the three in one resonance structures of nitrate? Or are you cherry picking random laws to fit a preconceived position?
It's not. Christian dogma doesn't even obey the law of identity.
