the Down-Grade Controversy

I found this on the Internet and it is a good read:

Spurgeon and the Down-Grade Controversy

"The first step astray is a want of adequate faith in the divine inspiration of the sacred Scriptures. All the while a man bows to the authority of God's Word, he will not entertain any sentiment contrary to its teaching. "To the law and to the testimony," is his appeal concerning every doctrine. He esteems that holy Book, concerning all things, to be right, and therefore he hates every false way. But let a man question, or entertain low views of the inspiration and authority of the Bible, and he is without chart to guide him, and without anchor to hold him."

This brief article is a good resource: Socinianism

"Socinians held skeptical views rooted in reason and rejected orthodox teachings on the Trinity and on the divinity of Jesus, as summarised in the Racovian Catechism. They also believed that God's omniscience was limited to what was a necessary truth in the future (what would definitely happen), and did not apply to what was a contingent truth (what might happen). They believed that, if God knew every possible future, human free will was impossible; and as such rejected the "hard" view of omniscience"

This sounds to me a lot like the "open view of God" that is becoming popular!
