I don’t think that’s Calvin’s concept. Calvin was the originator of TULIP, which has no standing with the concept of a person deciding anything, much less deciding to be saved.
This is a common, but serious, misinterpretation of Calvinism.
Calvinists do believe that people decide things. They just think that people decide according to what God has eternally ordained. Now whether this violates human freedom or not is a difficult philosophical question and not as obvious as many people think. It is important not to confuse your judgment as to what someone’s position
implies with what they explicitly believe. This is what Protestants do when they claim that Catholics “worship Mary” or “believe that Jesus is crucified all over again in the Mass.” Catholics have explanations of why their views do not imply these clearly heretical and blasphemous things, but some Protestants do not find the explanations convincing. Similarly, Calvinists have explanations for why their views do not take away human responsibility or make God the source of evil, but many other Christians find these explanations unconvincing.
I think it would be extremely interesting to find out the basis for OSAS (in a flash of time) I heard a Catholic Answers show where the guest attributed the concept to people like Billy Graham and Bill Bright (Campus Crusade for Christ). I suspect that if it didn’t arise there it was certainly given “legs” by those guys.
You’re confusing two things here: OSAS and instantaneous conversion are not the same. Many Arminian evangelicals believe in the latter and not the former. And depending on how you define your terms, many Reformed folks believe in the former but not the latter.
The phrase “in a flash of time” isn’t a very precise one, I think. What exactly are you saying happens “in a flash of time” in this view? I think all Christians believe that there is a moment when a person is regenerated, or at least begins to be regenerated. Traditionally it’s baptism–the Reformed and their many offshoots in Protestantism reject this. The Reformed hold that regeneration is a work of God that immediately
produces effects consisting of repentance, faith, and good works, but is not itself identical with any human act. They also believe that only the elect are regenerate (in contrast to Augustine, for instance). This is the original form of “OSAS,” though many folks distinguish it from OSAS.
Calvin used the phrase “sudden conversion” to describe what he believed to be the work of God’s grace bringing him from what he called “Papist superstition” to evangelical belief. There’s a lot of debate as to just what he meant by this. 16th-century Reformed folks generally did not look for evidence of a “conversion experience.” That was a more typically Puritan emphasis.
So I’d say that the “flash of time” view is best defined as the view that an instantaneous conversion
experience (a felt change of heart to which one can testify and assign a date) is to be identified with regeneration, either as its immediate effect (the Calvinist view) or its immediate cause (the Arminian view). This has never been as universally held as many people think–lots of evangelicals through the centuries have admitted that for some people it may be hard to p(name removed by moderator)oint the exact moment, while of course saying that such a moment must, objectively, have existed (which really isn’t controversial, I think, though for Catholics and other traditional Christians the moment would be baptism). Nor does it necessarily imply perseverance/OSAS.
I would say that Billy Graham and those like him actually moved
away from the highly experiential Puritan/Pietist tradition by identifying the moment of “being saved” with *intellectual *assent to the truth of John 3:16. This view was very controversial among more conservative evangelicals/fundamentalists, often derided as “easy believism.” My family came close to seeing Billy Graham as a false prophet for this reason, though usually softening the blow by admitting that he seemed to be personally godly and that his formal theology was basically orthodox. (Essentially we thought that he was a well-meaning believer who had nonetheless done much unintentional damage by giving people the impression that they were “saved” when they hadn’t really experienced the transforming power of God’s regenerating grace.)
