Labels: The labels here are not set in stone, but they are for the convenience of calling a certain theology something. The theology defines the label. The label does not define the theology. In other words these labels should be understood in the context in which they are given here. If people use the labels outside this context, then such usage may be different than how I am using them here.

Calvinist: Speaks in terms of election rather than salvation. There are presaved people who are nonetheless elect. They believe once elect, always elect, which is slightly different than once saved, always saved in that it includes the presaved elect. But as for those elect who have been born of God, it is inevitable that such people will continue in their faith and in a behavior consistent with that faith (in a lifestyle sense) till the end. But there are nominal Christians who still need to be saved. One's assurance of salvation is based upon the effects of being born of God and is measurable relative to one's behavior.

In his commentary on 1John 3:8-10 Calvin affirms the idea of the Perseverance of the Saints and against the Free Grace position:
"John (the apostle) denied that any one belongs to Christ except he who is righteous and shews himself to be such by his works; ... Hence two conclusions are to be drawn, that those in whom sin reigns cannot be reckoned among the members of Christ, and that they can by no means belong to his body ... all who are born of God lead a righteous and a holy life, because the Spirit of God restrains the lusting of sin ...  John not only shews how efficaciously God works once in man, but plainly declares that the Spirit continues his grace in us to the last, so that inflexible perseverance is added to newness of life. Let us not, then, imagine with the Sophists that it is some neutral movement, which leaves men free either to follow or to reject; but let us know that our own hearts are so ruled by God's Spirit, that they constantly cleave to righteousness ... John declares that all who do not live righteously are not of God, because all those whom God calls, he regenerates by his Spirit. Hence newness of life is a perpetual evidence of divine adoption." John Calvin

Secure Arminian: This is the BCBSR position. Holds a pre-salvation Arminian viewpoint and a post-salvation Calvinist viewpoint. Actually it could be argued that Joseph Arminius himself held a similar position saying, concerning the Perseverance of the Saints, "Election to salvation comprehends within its limits not only Faith, but likewise perseverance in Faith; and since St. Augustine says, "God has chosen to salvation those who he sees will afterwards believe by the aid of his preventing or preceding grace, and who will persevere by the aid of his subsequent or following grace; "believers and the elect are not correctly taken for the same persons." Joseph Arminius Thus he would word it as the Perseverance of the Elect, as would Calvinists.

Antinomian Secure Arminian: Pre-salvation Arminian viewpoint and post-salvation Antinomian Calvinist view point. The Antimonian viewpoint is simply that once born of God (saved), there is not necessarily any correlation between one's faith, behavior, and salvation status.

Arminian: Contrary to the fatalistic view of Calvinism, the Arminian views obtaining salvation as a matter of cooperation with God. One's free will is involved in the process of salvation. But this continues after having been born of God such that one can lose salvation if failing to cooperate to the end.

Legalistic Arminian: Though claiming to advocate salvation by faith, these promote a legalistic works-based salvation in which the maintenance of one's salvation is matter of one's performance. This group often makes a big deal of rituals ascribing spiritually regenerative properties to material things. Catholic sacraments are in accordance with this kind of spirit. And of course along with traditional Arminianism, this group believes salvation is loseable. See the web page on Legalistic Arminianism

Lutheran: Lutherans believe salvation is only rejectable by choice (And therefore since "choice" and cooperation is involved, this is Synergism - cooperation). However, such a choice can only be made after one has salvation. They believe you can lose your salvation. Or to say it another way, one maintains his salvation status by choice. However, they do believe "once elect always elect". But unlike Calvinists they believe that non-elect people can be born of God. But that such non-elect Christians will lose their salvation at some time.

Antinomian Lutheran: Similar to traditional Lutherans but believed that one's salvation is maintained by a trivial non-application oriented faith. See the web page on Antinomian Lutheranism

What the two extremes have in common is that neither accept the idea that there is an inevitable correlation between one's behavior, and salvation status after having come to faith in Christ.

1. It preaches easy-believism, misrepresenting the quality of faith that saves.
2. This leads to nominal Christian being decieved into believing they are saved.
3. Though not licentious of itself, it does inappropriately accomodate licentious behavior in the Christian community

The Danger of Legalistic Arminianism

The object of faith becomes one's performance rather than the atoning work of Christ
These people may be allegorically (and for some literally) likened to the group of the circumcision who took the position "Unless you are circumcised, according to the custom taught by Moses, you cannot be saved.", whom Paul zealously opposed in his letter to the Galatians, or likened to the Galatians decieved by the doctrine of the circumcision.
