Theology, Theology of Nature, and Natural Theology–What’s the Difference?

by Max Andrews

Theology is doubly revealed and many Christians often ignore God’s natural revelation as being a valid object of interpretation.  It’s all too often that many Christians reject many valid scientific theories.

“Theology is properly distinguished as natural and revealed.  The former is concerned with the facts of nature so far as they reveal God and our relation to him, and the latter with the facts of Scripture.” –Charles Hodge

Theology refers to the all encompassing knowledge of God.

Theology of Nature refers to the Book of Nature as revealed in Scripture (Ps. 19.1-4; Rom. 1.20)  Look at Psalm 19. When speaking of God it refers to his general name (El, Heb., continuous, abundant, universal). Some of the themes are creation’s contingency, Imago Dei, Stewardship, the fall, etc.

Natural Theology refers to the metaphysical implications of, say, intelligent design, the beginning of the universe, the moral law, beauty, etc.

“Some people, in order to discover God, read books.  But there is a great book:  the very appearance of created things.  Look above you!  Look below you! Note it.  Read it.  God, whom you want to discover, never wrote that book with ink.  Instead he set before your eyes the things that he made.  Can you ask for a louder voice than that?” -Augustine

How Einstein got to E=mc^2

by Max Andrews

In 1865 James Clerk Maxwell had unified electricity and magnetism by developing his equations of electromagnetism. It was soon realized that these equations supported wave-like solutions in a region free of electrical charges or currents, otherwise known as vacuums.  Later experiments identified light as having electromagnetic properties and Maxwell’s equations predicted that light waves should propagate at a finite speed c (about 300,000 km/s).  With his Newtonian ideas of absolute space and time firmly entrenched, most physicists thought that this speed was correct only in one special frame, absolute rest, and it was thought that electromagnetic waves were supported by an unseen medium called the ether, which is at rest in this frame.

Let an object in a rest frame simultaneously emit two light waves with the same energy E/2 in opposite directions (now having equal but opposite momenta), the object remains at rest, but its energy decreases by E.  By the Doppler effect, in another frame, which is moving at the velocity v in one of those directions, the object will appear to lose energy equal to

Creatio Originans and Time

by Max Andrews

The doctrine of creatio originans refers to God’s original conservation of creation–a sustaining causal relationship.  This doctrine typically entails an A theory of time.

A theory of time (dynamic):  The ultimate reality of time is tensed (God is in time)

B theory of time (static):  The ultimate reality of time is atemporal (God is outside of time)

The doctrine of creation implies an A theory of time (dynamic, tensed). If one adopts B theory of time, then things do not literally come into existence.  The whole four-dimensional  spacetime manifold exists coeternally with God.

Creatio continuans entails a B theory (a continual creation). According to B theory, all events are equally real. Yesterday is just as real as tomorrow and exist in the same moment. If creatio orignans fails, can B theory make more sense of conservation?

Can God act tenselessly on e to sustain it from t1 to t2 [a time interval]
