This is very odd theology, at least to me; "positionally...righteous in Christ"? Just what do you mean?
I happen to agree with this explanation in Positional Sanctification. Here is an excerpt:
So, again to be clear the righteousness is not of ourselves at all. It is only Christ's righteousness that allows us to be saved and sealed in the Holy Spirit in the present time, even though we are yet still sinners in this world. This positional aspect of sanctification is what allows assurance of salvation and assurance that God's promises apply to us as believers, etc. As a status this would be comparable to the juridical aspect of what we call justification. Christ's action justified us and gave us the permanent status of being positionally sanctified IN Christ.
I find it interesting that in making a case for this concept, the author makes not a single reference to any of the four Gospels. Why is that FK? Could it be because Christ never taught such nonsense (and no, 1 John is not a Gospel).
Your source says
This is not even Christian! What scriptural reference does he have for this? Also, how do you stand before the Father and not the Son and the Spirit, and, second, just when will the "saints" be perfected? At the instant of their death? Where does Jesus teach that? Isn't perfection something we attribute only to God? Or does he suggest that believers will become God?
To which is say Baloney! 1 Cor 6:11 presupposes that the "washed" and the "sanctified" are notto borrow Paul's own wordsof those who will not inherit the kingdom, namely the fornicators, idolaters, adulterers, effeminate, homosexuals, thieves, the covetous, drunkards, revilers, swindlers, etc., all of which will many Protestants be until their last breath no matter how much they have convinced themselves they abide in Christ and are made "just" by the his blood. [1 Cor 6:9-10]
Reference to 1 Cor 6:11 presupposes the "washed" are none of the above, and then some, and frankly I don't believe there are many in this world who are not a little bit of everything Paul considers unfit for the kingdom of heaven, the feel-good kumbaya self-congratrualtory rituals the Protestants perform for themselves every Sunday notwithstanding.
As for "progressive sanctification" supposedly mentioned in 2 Cor 7:1, it all boils down to Paul calling on the "saints" to cleanse themselves "from all defilement of flesh and spirit". To which I say: why bother, when every one "knows" for sure these "saved" will be made "perfect" at the end of their sinful life no matter what they do, think or say?!
And if they so hate sin (supposedly), now that they have been "regenerated," why do they need prodding by their idol Paul? Shouldn't that come to them "naturally"? I guess not.
And what about 1 Peter 1:6 your source uses as evidence of "experiential or progressive sanctification"? It speaks of trials (persecutions) which has nothing to do with sanctification, but calls on perseverance in faith, as hope for a better future promised them. Peter calls on the Christians to offer themsleves to God as sacrifice, imitaing Christ, that is to martyrdom.
Finally, your author also embellishes his worthless claims with 1 John 3:1-3 as scriptural backing for the assertion of the "ultimate perfect sanctification".
Verse 2 in particular says that we really don't know yet what we will be, but (somehow) we "know" [sic] that, when Christ appears, we will be [just] like him (!)because we will see him just as he is (?).
It seems to me that if they are going to be like him, as pure as he is, they will be perfect (i.e. divine). It sure seems like he knows what they will be even if he says he doesn't! I am sure the Mormons delight in in these verses as much as your author does.
And then verse 3 says that everyone who has this hope (in the previous verse he says "know") purifies himself as Christ is pure. What happens, pray tell, with someone who is "born again" yesterday and dies today? How can he purify himself as pure as Jesus is pure in one day? Or is there some magic involved?
But then 1 John says that
Well, then, this tells me there is not a single person on this earth "who abides in him", not one. So much for progressive sanctification, let alone final purification!
That whole essay, which on its face looks impressive, given all the biblical verses used as references, falls apart when these references are examined, and reveals that much of the holiness some people convinced themselves of is nothing but a feel-good delusion.
The sad thing is that it makes decent people feel good about themselves, but it also does much more people like Andrea Yates. She is also "saved" and "holy" in God's eyes, pure as snow, and destined to heaven. If Protestantism is true Christianity, I am glad I don't qualify as a Christian. In fact, I am proud of it.
