Well,you alone do not have the authority to determine for Christian doctrine what Calvinism is and is not. Calvinists do not have to match every iota of what John Calvin held --even Presbyterians don't hold to that pretension.
MOST of what is known as calvinism was actually structured and put down into a formal system AFTER John Calvin, as they used his writing s and Institutes as the "bible" to put it all down, but doubt even calvin agreed with all things seen calvinistic!
I tend to go along with that. But your "points" are of your own derivation. Many within Calvinism would say theat a 4-pointer is self-contradictory. Perhaps they are "Calvinistic" rather than really being a Calvinist.
MANY who taught at say DTS fell into this school of 4 pointers, so I tend to see them as being real calvinists, just not strong in the view of the atonement!
True. But many Arminians would say they believe in predestination also --yet differ radically with the same doctrine as believed by Calvinists.
many see that based upon god election of the plan, or of jesus, NOT individual election of each believer!
Of course one can.
See Dr McArthur, and other "leaky Dispy", such as myself!
True. Calvinists do not believe in the seven sacraments as taught by Roman Catholicism.
Because you have misunderstood what Calvinism is and is not. John Calvin's teachings on every nuance of theology is not the be-all and end-all in order to be considered a Calvinist.
IF yoyu see all of calvinism as necessary to be considered a real calvinist, holding to all of Covenant theolgy fro example, that is true, but many hold that its the Sotierology of calvinism itdelf that ios core of one being a calvinist ot not!
Like Spurgeon --I believe in what Calvin taught --"in the main." And yes, it would be a good idea to read much of what Calvin wrote and preached if you are granted a few decades of life --not utterly necessary --but a worthwhile pursuit. C.H.S. also said that the term "Calvinism" is short-hand for the doctrines of grace. It has been so for several centuries now.
