Here is the progression:
1). God identifies Himself as Abraham's protector and promises Abraham that he will indeed receive a reward.
2). Abraham believes God and it is credited to Abraham as righteousness.
3). God commands Abraham to now enter in a covenant with Him, and the sign of that covenant is circumcision.
How is election in Christ different?
It's not. That all looks good. But we need to remember the order of 2 and 3. Just as Abraham was righteous from faith alone, we are also righteous from faith alone. We then go and get baptized as a seal of that promise. But the baptism itself is not for salvation.
Neither does the holy Roman Catholic Church preach such an execrable doctrine.
The catholic church does teach that works are meritorious though--or that we can earn God's favor by our works.
Exactly. So, what does the Scripture say is the act of being reborn in Christ?
John 3:5 Jesus answered: Amen, amen I say to thee, unless a man be born again of water and the Holy Ghost, he cannot enter into the kingdom of God.
The "water" in that passage refers to birth. Read a couple verses on and Jesus reiterates it. Go further and we see that Jesus declared himself to be as the snake was lifted up in the desert. People looked to the snake and were saved--and likewise, we are saved by looking to Christ on the cross.
Romans 6:3 Know you not that all we, who are baptized in Christ Jesus, are baptized in his death?  For we are buried together with him by baptism into death; that as Christ is risen from the dead by the glory of the Father, so we also may walk in newness of life.
Yet....we are told a chapter earlier we are saved by Grace. Again...you are pulling a proof-text out of context to justify your point.
Titus 3:4 But when the goodness and kindness of God our Saviour appeared:  Not by the works of justice, which we have done, but according to his mercy, he saved us, by the laver of regeneration, and renovation of the Holy Ghost
Nothing there about baptism. It's faith alone in Christ alone by grace alone.
Acts 22:16 And now why tarriest thou? Rise up, and be baptized, and wash away thy sins, invoking his name. [/color]
The "calling on his name" is what saved...not the baptism part. You keep mixing that up.
