Actually, salvation is not placing one's faith on the cross. The cross was an instrument of torture that the Romans chose to kill its enemies. Our salvation is placing our faith in the Lord who died on a cross and rose from the dead 3 days later...
The gospel is attributed to the Lord Jesus not Paul or anyone else. It is the Lord who taught Paul what the good news were. This is best revealed in 2Cor 5:19 where it says, "Namely, that God was in Christ reconciling the world to Himself, not counting their trespasses against them, and He has committed to us the word of reconciliation." (NAU)
Anyone who preaches the good news of Jesus Christ must have also learned it at the Lord's feet.
I know that Israel is not the church and the church is not Israel, but I would like to know if you could expand on this area a bit more so that we can know how exactly you see the place of Jesus in both the Old and the New Testament.
Lastly, what's the overwhelming evidence that the church was not born in Pentecost? If not, where was the church born then and what was the purpose of Pentecost?
Let’s not forget that the Baptism of the Spirit of God that fell upon 120 believers in Acts 2 for the first time in all history. God made these believers a new temple made without hands where He began to make His abode in believers after the Lord ascended to the throne of glory and sat down at the right hand of the Majesty on High, (Mark 15:58, Jn 14:20, 23, 17:21, Acts 2:1-4, Col 1:27, etc.)
The church is not Israel, and Israel is not the church. The true church of this age was unknown until revealed to Paul. It was a secret in the mind of God.
Most Christians make the mistake of calling Pentecost the "birth of the church" (despite over whelming evidence to the contrary). In the Body of Christ, salvation is not through water baptism or any other work. It is through placing one's faith in the cross work of Christ alone. This is "Paul's gospel". Paul's message & ministry was differant than that of the 12 "circumcision apostles". Our commission today is to make known Paul's "gospel of the UNcircumcision", where Jew & Gentile are reconciled to God in one body through faith alone. No works, rituals or ordinances.
