Angainor, I think you’re touching dangerously close to, “once saved always saved.” Although personally I see the tension coming from what you’ve expressed in your last post, which right at the end gives echoes of, ‘simul justus et peccator’ (my apologies for misspellings).
I know that is very Catholic. I would ask, “Start what all over again?” Jesus said “it is finished.” We are forgiven. That’s it. We need never be thirsty again.
What do you mean by juxtaposing ‘it is finished’ and, ‘we are forgiven?’ Certainly you must at least make the distinction between the objective redemption accomplished on the cross and the subjective redemption as applied to believers.
Since we know that Jesus died for the sins of the whole world, the unavoidable conclusion of conflating objective and subjective redemption is that universalism is necessary, which is quite a tricky proposition.
Besides, we must be careful in parsing what exactly, “it is finished” means, because according to Paul all would have been in vain without the Resurrection. (In other words, let’s be fair to Jesus’ last words and not make them bear more weight than they were designed to carry.)
Now, the question is how to examine the subjective redemption of the believer. As the Epistle to Titus explains, “he saved us through the bath of rebirth and renewal by the holy Spirit” (Titus 3:5). Now what happens after we are (loosely paraphrased), ‘baptized and our sins washed away?’ (i.e., Acts 22:16). Which is equivalent to saying, after we’ve been baptized and clothed with Christ (cf. Gal 3:27).
Obviously this is the *beginning *of the Christian life.
What you seem to say is that one cannot, once the Christian life has begun and the soul has been washed and regenerated, he cannot fall away. As you said, “It is a construction of human reason that the soul is stained anew.”
This seems to me to be contrary to Our Lord’s teaching, and that of Scripture, although you say it is not of God’s word.
Take for instance, the Letter to the Galatians. Galatia was an estabilshed Christian church which Paul was writing to, to correct them.
It seems quite clearly that they were in danger of falling away-- or indeed, that some already had, for a false gospel (cf. Gal 1).
It is quite clear that he is speaking to those who are, ‘saved’ in Christ Jesus. After all, he refers to, ‘our freedom in Christ Jesus’ (cf. Gal 2:4). Besides this he asks them how they received the Spirit, indeed implying that they had received the Spirit (cf. Gal 3:2).
Paul certainly opposes the idea. After explaining that one becomes a child and then an heir of God after having been slaves (cf. Gal 4:6-7) he asks them if they want to become slaves again! (Gal 4:9). In context that is clearly forsaking the adopted sonship of God. He comments that he is in labor again until Christ be formed in them (Gal 4:19). In other words, Christ needed to be formed again in them, after they had forsaken him. He is, “perplexed” why they are choosing slavery under the law after having been free sons and heirs under grace (cf. Gal 4:20). His allegory of Hagar and Sarai needs no introduction-- the children of the slave women are driven out.
Hence he says, “For freedom Christ set us free; so stand firm and do not submit again to the yoke of slavery.” (Gal 5:1) He tells those who had fallen quite plainly that, “you have fallen from grace” (Gal 5:4). We know it is by grace we are saved, and it is quite clear what this means.
