With regard to the last article I published, I know many members of the body of Christ believe that one can’t be saved under the Gospel of the Circumcision today, instead believing that one can only be saved under Paul’s Gospel right now, but passages like John 3:16 and John 20:31 combined with Romans 10:9-13 (among many others) seem to imply that this isn’t the case, since lots of Christians do indeed believe and do these things, and I see no reason to think that these passages aren’t currently true (especially since we know that, at the very least, they’re going to be true during the Tribulation, so why not now too, when there are no Bible verses which say they aren’t true right now?).
This is why I actually do think that “whosoever shall call upon the name of the Lord shall be saved” is indeed true for Gentiles (and Israelites) today too, even if only at the time one does so, which means that basically every person who confesses the Lord Jesus (believing Him to be the Christ and the Son of God), and of course who believes in their heart that God has raised Him from the dead, does get saved at the time they do so (yes, including Roman Catholics and Seventh Day Adventists and Pentecostals and Independent Fundamentalist Baptists and Jehovah’s Witnesses and even Mormons). The problem is, they’re being saved under the Gospel of the Circumcision, and if they don’t then follow up their salvation with the good works that are still required to maintain one’s salvation under this Gospel (such as water baptism, not to mention following any other commandments that they’re required to follow at this time), they very well might lose their salvation and fall under the category of the type of person to whom Jesus will say, “depart from me, ye that work iniquity,” after He returns (if they happen to be alive at that time — if not, they might get to go on to the New Earth rather than end up in the lake of fire, presuming they aren’t among those mentioned in Revelation whose names won’t be written in the book of life, but they’ll have lost the opportunity to get to live in the kingdom of heaven for 1,000 years, unless, perhaps, they’re Gentiles who happened to help out the believing Israelites who are persecuted during the Tribulation, of course, but that’s technically not considered to be salvation).
So basically, I believe that nearly all Christians at least become “guests” of the Israel of God — if not full members of the Israel of God — the way that Cornelius did (at least those Christians who don’t instead join the body of Christ, and those who do join the body of Christ can’t ever lose their salvation), but that many of them might not remain saved the way that Peter did, which is why many Christians might not actually be saved (or at least might not actually be saved anymore, even if they were saved at one time; although they will eventually experience the general salvation connected with Paul’s Gospel — because of Christ’s death for our sins, burial, and resurrection on the third day — of course, even if they also missed out on the special salvation connected with both Gospels).
And with that also being said, this all means that some Christians saved under the Gospel of the Circumcision actually do remain saved (such as those who perhaps have been taught that God is a three-in-one being yet haven’t fully internalized and accepted this doctrine as truth, perhaps not even realizing that they don’t fully believe it to be true, as just one example — and I could be wrong, but I suspect that God might be merciful when it comes to those who misunderstand what the full requirements for salvation under this Gospel actually mean, so it could be that even those who do fully believe the “orthodox” idea of the Trinity don’t lose their salvation for that mistake, even if they can’t join the body of Christ as Trinitarians).
As for who is actually “in” or “out,” so to speak, when it comes to salvation under the Gospel of the Circumcision, is for God to decide, not me. But it does mean that, while I don’t believe all Christians are necessarily currently saved, I suspect that a fair number of them likely actually are still saved, at least as far as this Gospel goes (although whatever that number might be, I wouldn’t even try to guess, but it does mean that I try to give all people who call themselves Christians the benefit of the doubt, and am willing to fellowship with them, similar to the way that Paul fellowshipped with members of the church called the Israel of God too, even if I believe they’re quite mistaken about a lot of their doctrines, just as many members of the Israel of God also were in Paul’s time in other — and, yes, sometimes even similar — ways; of course, whether they’ll fellowship with a “heretic” like me is a whole other question).
That’s not to say I think we should begin attending the church services of most Christians, of course. But I‘ve also come to realize that those of us in the body of Christ might be a little too harsh towards Christians who aren’t in the body of Christ, since, even though they do believe a lot of incorrect doctrine (especially when it comes to Infernalism, Annihilationism, and the Trinity), many of them probably are still legitimate members of the church called the Israel of God (or at least connected with it in some way, if Gentiles don’t become full members — I’m not 100% sure whether or not they do become full members at this time, but they’re still saved if they obey the requirements of this Gospel). That being said, I doubt most of them want to fellowship with us, since they generally do think those of us in the true body of Christ are heretics for not believing in never-ending punishment and the Trinity (among other things). But I do still think we need to start being a little more gracious with the Christians we encounter who aren’t in the body of Christ than we might have been in the past.
