Just came on board...
And one major difference between this, and what I've heard from any Protestant source, is that the emphasis is not on Christ uniting himself to and saving certain individuals, nor saving all individuals, but rather saving humanity, or mankind. When he assumed human nature, he assumed that which is held in common by all human beings. He became not just "a man" but he became man. He became humanity. He fulfilled and completed, justified, and glorified humanity.
Amen, the last Adam!
Why this distinction? Because he came to overthrow death, and Satan, who wielded death to keep humanity enslaved.
Hebrews 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; 15 And deliver ( to snatch away, rescue, save) them who through fear of death were all their lifetime subject to bondage.
