Calvinism is not the gospel, but does indeed have gospel truth, but, then again, Calvinistic teaching is different from one Calvinist, to another, just as Amenianism is different among those who would be considered such ~ according to each school of teachings on doctrine of Soteriology the branch of theology dealing with the study of salvation from sin and condemnation.
The term comes from the Greek soterion, “salvation,” and is also related to soter, “savior.” Soteriology relates to several branches of theology in that it asks who is saved, by whom, from what, and by what means.
When all such things are address by the two schools among each who teach the two school ~ diversity is seen to reign among each of them, so, no pure form of either anymore exist, or if it ever did , which we beleive it has never, since God's very elect, had a few who were truly enlightened only from the Calvinistic position, that never held to such teachings as infant baptism; the necessities of gospel mean in regeneration; free justification by the faith "of" Jesus Christ alone, as the only means...... faith by the the elect sinner, is only at best the evidence of regeneration, it is no medium by which salvation from sin and condemnation comes to the elect sinner~an error that some Calvinistic believers hold to.
Without question those men and women who teach a synergistic means of salvation, with a sinner having an active part in his salvation from sin and condemnation are in error, serious error concerning the true doctrine of the free grace of God, as it relates to free justification through the redemption that is in the obedience and faith "of" Jesus Christ. Romans 3:21-24; Acts 3:16; Galatians 2:16; 2:20,21; Philippians 3:9; etc.
For sure they are not practically saved from error to truth, impossible ~legally speaking, yes many of them are, since salvation from sin and condemnation, one's knowledge is not a perquisite to be saved in this sense, since legally, a sinner is saved by Jesus' faith and obedience alone. The sinner's works, pro or con, are excluded altogether, in order to maintain and preach a pure gospel of the doctrine of free grace.
Some are, also, some who call themselves belonging to the school of Calvinism are lost, and still in their sins ~ lip service proves nothing either way from either school. James 2:17--20.
But in closing I will add this: God, with whom we all have to give account, has strongly placed a curse upon all who preach another gospel, one that has man having an active part in, this should concern each and every person to diligently make sure that what he believes and teaches is according to the gospel of the free grace of God through his Son's acting as a surety for God's elect, and what he offered unto God for their sins was his perfect life of faith and obedience as a fulfillment of what the law of God demanded in order to freely impart eternal life to the sinner.
