Basic to the unbeliever’s worldview is a denial of creation – the ordered arrangement of the universe according to the mind of God.
The Christian worldview is that not one piece of the created order is where it is, at the time it is, and the size it is , that is not the result of God’s ultimate plan for His creation.
Knowledge requires the ability to differentiate between individual objects (One- and- Many question). This is done by means of universals, or what we might call categories. Examples of categories would be horse, cat, chair, trees, plants and so forth. In the Christian worldview, categories or universals, are part of the creation act of God. This is what unifies everything in the universe (unity and diversity), otherwise we just have a lot of ‘abstract particulars’ that don’t relate to anything else. Particulars (things, events, words) need something that connects them to something else that will provide meaning to the particular whatever it might be. Right at the foundation of the universe (Genesis 1) God created particulars and kinds (universals), ” The earth brought forth vegetation, plants yielding seed, each according to its kind …” Genesis 1:11-12.
In God’s own being, the Trinity, we find both unity and diversity. Christian philosopher, Cornelius Van Til recognized the question of the One-and-Many as a metaphysical issue. “Using the language of the One-and-Many question we contend that in God the one and the many are equally ultimate. Unity in God is no more fundamental than diversity and diversity in God is no more fundamental than unity.”
The doctrine of the Trinity provides a solution to the problem of knowledge , the one-and-many or universals and particulars, and therefore a solution to the issues of relationships, or community. In the Trinity the absolute self-sufficient God is both unity and diversity. Creation reveals a one-and-many universe brought into existence by a one-and-many triune God.
The universe is not an accumulation of unknowable abstractions but a creative act of God. Without such a belief in a unifying principle in the universe, science is not possible. It is the unifying principle, the common denominator, that provides order and coherence – rationality – to the universe. This is one of the unproven assumptions of science. It is no coincidence that science has grown on the back of a Christian culture and worldview.
