MT said:So given that Romans 5:1-11 is written to believers, can we affirm as De Maria does that Romans 5:6 applies to all humanity without exception?
Yes. And not just to all humanity but to all creation:
King James Version (KJV)
21 Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God.
22 For we know that the whole creation groaneth and travaileth in pain together until now.
23 And not only they, but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, to wit, the redemption of our body.
The answer to that question is clearly no, since then we would have to apply virtually everything else in this passage to all of humanity.
Not if you speak English.
Obviously when he says, us, we and our, that refers to believers.
And obviously when he says, "the ungodly", that refers to everything and everyone that is not divine. Everyone that is not God.
But if we were to do this, numerous absurdities would follow.
Of course. Because you want to exaggerate everything in order to create a nonsensical straw man you can knock down. But that is not truth. You simply endeavor to justify your errors.
