"Calvinism is wickedness. The very thought of it is repugnant".

"But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man" (Heb. 2.9). For every man or just some men?

"Ye stiffnecked and uncircumcised in heart and ears, ye do always resist the Holy Ghost: as your fathers did, so do ye" (Acts 7.51). In other words, it didn't have to be this way. Just as your fathers Augustine, Luther and Calvin resisted the Holy Spirit, so do Calvinists today.

The last point of TULIP is the tricky one, because it doesn't mean OSAS, but to Calvinists it means they will be made to persevere to the end. But they can never know for sure if they are really saved, because they have no assurance they will persevere to the end. They could blow someone's brains out tomorrow which proves they were never saved to begin with.

Whereas true Christians can never lose salvation no matter what.
