>> Rom 10:9 That if thou shalt confess with thy mouth the Lord Jesus <<
Just what is it that you think you are supposed to confess ABOUT Jesus? That he was some guy? Even Josephus, Marx, Hitler, and Stalin confessed that much. But you are denying the Lord Jesus, making him ONLY a man! You should know that Paul wrote to the Greeks, and that the Greek bible used the word, "Lord" to mean "YHWH."
>> Literally they are separate entities, separate bodies, one penetrating the other. the use of "one" is to indicate unity not being identical <<
Is my hand identical to my foot? Of course not! They are part of me, though, and I am one. A woman and a man become part of the same body. This is not mere poetry! Ask an immunologist! Ask an obstetrician!
>> So you're ok promulgating the doctrine that NT believers do greater works than God, is that right? <<
Of course not! Jesus conquered sin and death. Even you believe that, right? No human will do something greater than conquering sin and death. So, obviously, you are misusing that quote.
First, I can't find YHWH used in the new testament even though it is common in the OT.
Second, to confess the Lord Jesus means that you have to make Jesus Lord and that goes beyond just saying it. Confession indicates making your beliefs of mind and heart one. No, not one as in identical, but one in unity, singleness of purpose.
Futhermore, is isn't making the glorified Christ lord, it is making the lowly, mocked and tortured Jesus who suffered for us your lord. Anyone can kneel before a powerful, glorious being but it is different to confess as lord the one that was stripped, humiliated, beaten and killed as lord.
And I doubt that Marx, Hitler or Stalin did that.
Was/is Jesus a man? Of course, the Bible says so repeatedly.
But was he "only" a man or 'merely' a man? No!
Jesus conception was not of a man's seed, but of a perfectly created one that did not have the sinful nature that we share.
Hbr 2:14 Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil;
He took part but did not partake. He shared the flesh but not the blood. The flesh was of Mary but the blood from his Father.
In that he is unique among men. This gave him the ability to resist temptation...and yes, unlike God, Jesus was tempted. He was tempted to resist his terrifying crucifixion but submitted to his Father's will.
Also, he was tempted in all ways like we are...with power, self fulfillment, lust, etc. but he was able to resist because of a strong will and sinless blood.
He had to be a man in order to fulfull the passover laws and be the perfect sacrifice, being one of the sheep of the flock. But it was his shedding of sinless blood that paid the price for our sins.
So you see, IMO it is extremely important to get the details as precise as possible in understanding who God and Jesus are and what it was that they accomplished.
Had Jesus been just another man, or had he been a god-man, he couldn't have fulfilled his role.
