Does Calvinism teach that we are born-again TWICE!

I know the following is quite long, but any Christian who takes 2Tim 2:15 seriously will be willing to study to show himself approved unto God, a workman who need not be ashamed, one who rightly divides the word of Truth.

The problem seems to be that many people here are trying to discuss things they don't understand. There is a distinction between regeneration, salvation, justification, redemption, sanctification, and glorification.

Regeneration, according to Easton: In Tit 3:5 it denotes that change of heart elsewhere spoken of as a passing from death to life (1Jo 3:14); becoming a new creature in Christ Jesus (2Co 5:17); being born again (Joh 3:5); a renewal of the mind (Rom 12:2); a resurrection from the dead (Eph 2:6); a being quickened (Eph 2:1, Eph 2:5). This change is ascribed to the Holy Spirit. It originates not with man but with God (Joh 1:12, Joh 1:13; 1Jo 2:29; 1Jo 5:1, 1Jo 5:4). As to the nature of the change, it consists in the implanting of a new principle or disposition in the soul; the impartation of spiritual life to those who are by nature "dead in trespasses and sins." The necessity of such a change is emphatically affirmed in Scripture (Joh 3:3; Rom 7:18; Rom 8:7-9; 1Co 2:14; Eph 2:1; Eph 4:21-24).

Conversion: The turning of a sinner from his sin to God. Men are converted when, by the influence of divine grace in their souls, their whole life is changed, old things pass away, and all things become new (Act_26:18).

Salvation: In the New Testament it is specially used with reference to the great deliverance from the guilt and the pollution of sin wrought out by Jesus Christ, "the great salvation" (Heb 2:3).

Justification: the judicial act of God, by which he pardons all the sins of those who believe in Christ, and accounts, accepts, and treats them as righteous in the eye of the law, i.e., as conformed to all its demands. In addition to the pardon (q.v.) of sin, justification declares that all the claims of the law are satisfied in respect of the justified. It is the act of a judge and not of a sovereign. The law is not relaxed or set aside, but is declared to be fulfilled in the strictest sense; and so the person justified is declared to be entitled to all the advantages and rewards arising from perfect obedience to the law (Rom 5:1-10).

Redemption: The purchase back of something that had been lost, by the payment of a ransom. There are many passages in the New Testament which represent Christ's sufferings under the idea of a ransom or price, and the result thereby secured is a purchase or redemption (Compare Act 20:28; 1Co 6:19, 1Co 6:20; Gal 3:13; Gal 4:4, Gal 4:5; Eph 1:7; Col 1:14; 1Ti 2:5, 1Ti 2:6; Tit 2:14; Heb 9:12; 1Pe 1:18, 1Pe 1:19; Rev 5:9). The idea running through all these texts, however various their reference, is that of payment made for our redemption. The debt against us is not viewed as simply canceled, but is fully paid. Christ's blood or life, which he surrendered for them, is the "ransom" by which the deliverance of his people from the servitude of sin and from its penal consequences is secured. It is the plain doctrine of Scripture that "Christ saves us neither by the mere exercise of power, nor by his doctrine, nor by his example, nor by the moral influence which he exerted, nor by any subjective influence on his people, whether natural or mystical, but as a satisfaction to divine justice, as an expiation for sin, and as a ransom from the curse and authority of the law, thus reconciling us to God by making it consistent with his perfection to exercise mercy toward sinners" (Hodge's Systematic Theology).

Sanctification: the work of the Holy Spirit bringing the whole nature more and more under the influences of the new gracious principles implanted in the soul in regeneration. In other words, sanctification is the carrying on to perfection the work begun in regeneration, and it extends to the whole man (Rom 6:13; 2Co 4:6; Col 3:10; 1Jo 4:7; 1Co 6:19). It is the special office of the Holy Spirit in the plan of redemption to carry on this work (1Co 6:11; 2Th 2:13).

Perseverance: God continuing that which is began in regeneration. Php 1:6 Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ:

Glorification: To make glorious in the eternal state of complete perfection.

When these terms are used interchangeably confusion often results.

The ordo salutis (order of salvation) is the theological doctrine that deals with the logical (not temporal) sequencing of the benefits of Salvation worked by Christ which are applied to us by the Spirit. This first thing to remember is that we must never separate the benefits (regeneration, justification, sanctification) from the Benefactor (Jesus Christ). The entire process (election, redemption, regeneration, etc.) is the work of God in Christ and is by grace alone. Election is the superstructure of our ordo salutis, but not itself the application of redemption.

Regeneration, the work of the Holy Spirit which brings us into a living union with Christ, has a causal priority (again, logical, not temporal) over the other aspects of the process of salvation. God opens our eyes, we see. God unplugs our ears, we hear. Jesus calls a dead and buried Lazarus out of the grave, he comes. In the same way, the Holy Spirit applies regeneration, (opening our spiritual eyes and renewing our affections), infallibly resulting in faith. All the benefits of redemption such as conversion (faith & repentance), justification, sanctification and perseverance presuppose the existence of spiritual life (regeneration). The work of applying God's grace is a unitary process given to the elect simultaneously. This is instantaneous, but there is definitely a causal order (regeneration giving rise to all the rest). Though these benefits cannot be separated, it is helpful to distinguish them. Therefore, instead of imposing a chronological order we should view these as a unitary work of God to bring us into union with Christ.

We must always keep in mind that the orders expressed occur together or happen simultaneously like the turning on of a light switch or a faucet. But God turns on the light/faucet, so to speak. All aspects of the work of God continue together throughout the life of a Christian.
