Far too often I find Christians dismissing something because it’s “philosophy” and not from the Bible, a creed, a confession, etc. In my experience, many people tend to accuse Molinism as philosophy. To follow this brief tangent, middle knowledge and Molinism isn’t a philosophical grid being laid over Scripture; rather, it’s a derivation of a commitment to certain principles already obtained from Scripture. (See The Molinism Directory for more on that issue.) Well, it just happens to be the case that I saw a tweet yesterday making this same claim about Molinism being philosophy. (This particular tweet simply categorizes Molinism as philosophy but it’s still dismissed in the long chain of preceding and succeeding tweets.)
If we are pursuing truth then there are many means to discovering what the truth is [about God, reality, etc.]. It’s incredibly naïve to dismiss something because it is not in a preferred category. If we are pursing truth then it would be a category error to dismiss Molinism simply because it’s philosophy (according to the person making the claim). Feel free to disagree with Molinism but do so on a consistent basis and refute it via Scriptural witness, theological reflection/considerations, logical and metaphysical consistency, etc.
