As additional thought growing out of some questions on my earlier post, concerning Paul's theology of salvation, and how universal it was or wasn't.
I think Paul makes (what would later be articulated more clearly) a distinction between salvation, justification, and sanctification. In his system of thought, just as all were stained by Adam's sin, so all are redeemed by Christ. All means all. It isn't about "each" but "all" -- not about individuals but rather about the whole of humanity, which, from a rabbinic understanding was "present" in Adam. And so in Christ, the new Adam. "For as in Adam all die, so also in Christ shall all be made alive."
This is where the distinctions between "faith in" and "faith of" are important, and it's sad to see the NRSV has drifted in the former direction when the latter, as found in the KJV, makes more sense. (Note most especially Gal 2:16,20 3:22) It is the faith of Christ -- his faithfulness unto death -- that saves us.
Salvation is, in this sense, literally "healing" -- that is, healing the wound of sin that has affected the whole of creation, all of humanity, and with which we suffer willy nilly. We recover some of this sense of the meaning of "salvation" as healing when we speak of "the only Name given under heaven for health and salvation..." This is the opening of the door to eternal life.
Justification is another matter, and begins to involve the response of each individual to the free gift; it involves going through the door. This is where personal faith in Christ comes in. (Rom 3:25-26; cp 4:16) Not all will accept it, but all have been made capable of accepting it.
Sanctification follows, again as God's gracious offering, and is entering the room and maybe even sitting down! Or better, falling before the throne...
It is part of our task to distinguish between the sufficient belief in salvation for those who explicitly have chosen Christ and the possible hope that Christ is big enough so that all can find him and be found by him -- maybe the latter ones not even knowing it is Christ who has saved them until they come into his presence revealed in glory. I prefer to follow Paul into that realm of possibility that "all shall be made alive," while keeping one foot well-planted in the sufficient security that "all who call upon his name are saved." This, to me, seems to be where the best evangelism comes from, leaving the door open and reaching out beyond it; as, indeed, Christ did when he left his Father's side to come to us. As "little Christs" we are honored to assist in spreading that word, and the greater the graciousness of our speaking, the more will be won, and the further the word will spread...
