I hesitate to use theological labels and attempt to stay strictly in a more Biblical theology. I am forced by the very clear and direct statements in the New Testament to hold to a sovereign election of God that is unmerited by those chosen. My scripture reasons are as follows -
"who saved us and called us with a holy calling, not according to our works but according to his own purpose and grace. This grace was given to us in Christ Jesus before the ages began," (2Tim 1:9 NRSV)
"We are always bound to thank God for you, my friends beloved by the Lord. From the beginning of time God chose you to find salvation in the Spirit who consecrates you and in the truth you believe." (2Thess 2:13 REB) *
I find the arguments for "beginning" more persuasive then the NRSV "firstfruits"
"When the Gentiles heard this, they were glad and praised the word of the Lord; and as many as had been destined for eternal life became believers." (Acts 13:48 NRSV)
*
It does NOT read: those foreseen to believe were destined to eternal life!
"For those whom he foreknew(
proginosko) he also predestined to be conformed to the image of his Son, in order that he might be the firstborn within a large family. And those whom he predestined he also called; and those whom he called he also justified; and those whom he justified he also glorified." (Rom 8:29-30 NRSV) *
It reads "who" he foreknew, not "what" he foreknew. Those rejected by Christ he never knew, Matt. 7:23. This Greek 'proginosko' in 1 Pet. 1:20 is translated "destined" by the RSV, NRSV & "predestined" by the REB.
"Even before they had been born or had done anything good or bad (so that God’s purpose of election might continue, not by works but by his call) she was told, 'The elder shall serve the younger' ... So then he has mercy on whomever he chooses, and he hardens the heart of whomever he chooses." (Rom 9:11-12 & 18 NRSV) *
v24 of this discussion in Romans 9 shows this includes Gentiles as well as Jews and it is applied to the New Covenant.
"So too
at the present time there is a remnant, chosen by grace. But if it is by grace, it is no longer on the basis of works, otherwise grace would no longer be grace." (Rom 11:5-6 NRSV)
"...and all who dwell on earth will worship it, every one whose name has not
been written before the foundation of the world in the book of life of the Lamb that was slain." (Rev 13:8 RSV) *
This is exact wording is retained in the ESV version of the RSV. The Good News Bible translates it -
"All people living on earth will worship it, except those whose names were
written before the creation of the world in the book of the living which belongs to the Lamb that was killed." (Rev 13:8 GNB92)
"No one can come to me unless drawn by the Father who sent me; and I will raise that person up on the last day." (John 6:44 NRSV)
"...just as he
chose us in Christ before the foundation of the world to be holy and blameless before him in love." (Eph 1:4 NRSV)
"
By God’s act you are in Christ Jesus; God has made him our wisdom, and in him we have our righteousness, our holiness, our liberation. Therefore, in the words of scripture, ‘If anyone must boast, let him boast of the Lord.’" (1Cor 1:30-31 REB)
"since you have given him authority over all people, to give eternal life to all whom you have given him." (John 17:2 NRSV)
"Peter, an apostle of Jesus Christ, To the exiles of the Dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia,
who have been chosen and destined by God the Father and sanctified by the Spirit to be obedient to Jesus Christ and to be sprinkled with his blood: May grace and peace be yours in abundance." (1Pet 1:1-2 NRSV)
"And if the Lord had not cut short those days, no one would be saved; but for
the sake of the elect, whom he chose, he has cut short those days." (Mark 13:20 NRSV)
I find myself in agreement with the Confessions and Catechisms coming out of the Protestant Reformation.
