We being good Bible-Believing Internet Discernmentalists believe Solo Scriptura and teach the whole Bible and only appeal to the whole Bible and no other sources nor let culture interpret the Bible as we appeal to our heroes who appeal to John Calvin (a source outside the Bible) who appealed to Saint Augustine (a Roman Catholic apostate and another source outside the Bible) and also secular/pagan philosophies such as neo-Platonic dualistic rationalism and an epistemology of Aristotelian logic (more sources outside the Bible) to bring you our important teachings on Sound Bible Doctrines.
John Calvin quoted Cicero constantly. The Puritans regularly appealed to both reason and nature as support for their Calvinism. I can’t count the number of times I’ve heard a Calvinist talk about “the freedom of God.” The Westminster Confession of Faith begins with describing God as the “fount of all being.”
Discernmentalists seem to be under the impression that Calvinism only comes from Scripture whereas every other theology is a collection of extra-biblical (cultural) arguments, and that’s so self-evidently false as to be literally ridiculous. EVERY theology musters up a combination of proof texts, logical extrapolations of varying quality, appeals to God’s character, etc. Calvinism has no objectively firmer grounding than Arminianism or any other school of theology. (In fact our favorite Bible-writer Saint Paul also appealed to cultural sources outside the Bible as well).
Now many Bible-ignorant heathens reject our Clear Teaching that we must follow the whole Bible and never any source outside the Bible because they’re corrupting Doctrine—but as we’ve shown it is important to follow the whole Bible and only the whole Bible without appealing to outside sources or letting culture interpret it and only we do that.
