Those are the 5 points, but Augustine believed the same things and others prior to Calvin came to the same conclusion based upon Scripture. Call us Calvinists if you wish, but the doctrine traces to Scripture itself and was expressed outside of Scripture at least by the 300s.
"The old truth that Calvin preached, that Augustine preached, that Paul preached, is the truth that I must preach to-day, or else be false to my conscience and my God. I cannot shape the truth; I know of no such thing as paring off the rough edges of a doctrine. John Knox's gospel is my gospel. That which thundered through Scotland must thunder through England again."—C. H. Spurgeon
TULIP never was the church's doctrine until or after Calvin.
We could agree I think that it reached it's full bloom and completion into a separate scripture-based religion under Calvin.
You can find pieces of TULIP, heck I agree with pieces, in many different places and back-read this as "Calvin". But the full-blown TULIP? No.
It's like we've been saying; you can't take part and not harmonize it with the whole and call it 'scriptural.'
Calvinism isn't that big a deal. Just look at it as someone trusting God on absolutely every single possible anything and you've got it.
There's nothing wrong with it.
Just on the face of it, how can Calvinism be Jesus's teaching? What was Jesus's telling us to do? Why bother?
Was Jesus teaching something we have no free will or ability to do? Is Jesus saying: "Repent (you elect who can do no different)!'
Calvinism vanishes all meaning from The Gospel.
