I suspect that is impossible.
The specific beliefs of Calvinism are born out of rejection of the teachings of the Catholic Church and the Remonstrants. How can you discuss Calvinism without comparing it to other belief systems? You can't.
I completely agree, only I would add (no suprise here) that in rejecting Rome, Calvinism seeks to return to the faith of the early church, the faith of the apostles, the faith revealed in Scripture by the Holy Spirit.
If Rome had not erred from 400 A.D. onward, there would be no Calvinism, no Protestantism. There would be only Christianity.
But that isn't the way of the world.
I refer all to Topcat's quotation from Rev. Greg Bahnsen...
"Rome has not essentially changed. Rome declared that what it said at the time of the Reformation was infallible and could not change. Declared it to be irreformible truth. Rome has not changed and precious truths of God's word are still worth upholding even at the cost of unity even at the cost of being considered "troublemakers" in the religious world. We need to guard the antithesis against the destructive error of Rome." -- Dr. Greg L. Bahnsen, THE REFORMATION, October 28, 1990. "The Reformation is dying daily in our day when the Ecumenical Movement, and other forces like unto it, wish to soften the antithesis with Rome, today. I want to assure you that it's not my pugnacious debating nature that makes me say we must exalt that antithesis and guard it. It's my love for the Lord Jesus Christ and the purity of His word.
