Greetings again Right Divider. I appreciate your claim, but we seem to read Acts differently. I am not sure what is the relevance or what you are asking in reference to Peter healing everyone.
Because there are many things that the twelve did with regards to the people of Israel that are not relevant to the body of Christ. Peter was still preaching the gospel of the kingdom and NOT the gospel of the grace of God. Peter could not be preaching the gospel of the grace of God because it was NOT yet revealed. You can't preached something that you don't know.
I would be interested as to how you understand the following, especially verse 8:
Galatians 2:7-8 (KJV): 7 But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter; 8 (For he that wrought effectually in Peter to the apostleship of the circumcision, the same was mighty in me toward the Gentiles)
There are TWO different gospels being preached (and there are more than two gospels in the Bible). THAT is the reason for the division and NOT some "division of labor" as you falsely claim. Once again, a "division of labor" makes no sense when we see that the TWELVE apostles for the TWELVE tribes get to preach to the minority and the SINGLE apostle Paul takes the vast majority. Were they bad at math?
We have little information about the preaching efforts of all the Apostles, apart from the record in The Acts and the various Letters. The Acts reveal that Paul went on three major Missionary Journeys, mostly to the Gentiles. And then he was in Rome preaching for two years, despite the fact that he was a prisoner, but the gospel was not bound.
Paul was an apostle and not a "missionary".
I am a little bit amused by your continual use of “Churchianity”. I do not support the term “Church”, as it is used to describe a particular church such as the Baptist Church, the Catholic Church or the Church of England. The Biblical term relates more to an assembly of the believers who have responded to the call of the gospel. Perhaps you do not belong to a Church.
I use the term Churchianity to describe the mass confusion that you share with much of the so-called "church" that twists the Bible into a pretzel to get to (among other things) the "one gospel" fairy tale.
I belong the church which is His body. The one that only Paul describes.
I am still confused as to what you claim concerning this subject, especially the concept of two different gospels. Perhaps to clarify could you answer some of the following?:
1. Did Jesus preach a different gospel to Paul?
Without a doubt. How can you explain that fact that Jesus is never shown to use the word "grace" even ONCE during His time on earth? That is quote telling, but I'm sure that you pull out anything answer from your Churchinaity.
2. Were people saved by the gospel Jesus preached?
It depends on the meaning of saved. Not every use of the term is the same throughout the Bible.
Eternal life is a gift that is independent of the various gospels in the Bible. It always comes by faith in God and believing what He says.
3. Is the teaching in Matthew 5-7 still relevant to the believer today, and necessary as a way of life?
In the book of Matthew, the LORD Jesus Christ is preaching to His people, Israel. I'm really surprised that you don't know this.
Perhaps you did not see what Jesus taught later:
Matt 10:5-8 (AKJV/PCE)
(10:5) These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into [any] city of the Samaritans enter ye not: (10:6) But go rather to the lost sheep of the house of Israel. (10:7) And as ye go, preach, saying, The kingdom of heaven is at hand. (10:8) Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely ye have received, freely give.
Do you follow these instructions today? Do you heal the sick, cleanse the lepers, raise the dead.... ? I didn't think so.
4. What about the 3000 who believed at Pentecost? Will they be saved? Or did they need to also be converted by Paul and only then receive OSAS?
What about them?
They were the part of the remnant of Israel. You should do a little study on that topic.
Note carefully the future tense here:
Acts 2:47 (AKJV/PCE)
(2:47) Praising God, and having favour with all the people. And the Lord added to the church daily such as should be saved.
Why is it "should be saved"? Why not just saved?
Paul uses past tense:
Eph 2:8-9 (AKJV/PCE)
(2:8) For by grace are ye saved through faith; and that not of yourselves: [it is] the gift of God: (2:9) Not of works, lest any man should boast.
2Tim 1:8-11 (AKJV/PCE)
(1:8) Be not thou therefore ashamed of the testimony of our Lord, nor of me his prisoner: but be thou partaker of the afflictions of the gospel according to the power of God; (1:9) Who hath saved us, and called [us] with an holy calling, not according to our works, but according to his own purpose and grace, which was given us in Christ Jesus before the world began, (1:10) But is now made manifest by the appearing of our Saviour Jesus Christ, who hath abolished death, and hath brought life and immortality to light through the gospel: (1:11) Whereunto I am appointed a preacher, and an apostle, and a teacher of the Gentiles.
The "appearing of our Saviour Jesus Christ" does NOT refer to His earthly ministry to Israel but His appearing to Paul with special revelation. Paul speaks at length about this throughout his epistles.
5. Is Mid-Acts Dispensationalism closely linked to OSAS, or is there a range of opinions, some supporting OSAS, and others rejecting OSAS?
You seem to be terribly hung up on OSAS.
In the dispensation of the grace of God salvation is freely given and cannot be lost. If you don't have that assurance, then you're probably not saved by grace through faith.
