It seems common among Christians on both sides of the "Creationist vs. Theistic Evolution" debate to accuse one another of Deism rather than Theism. Deism is the idea that, while God was intimately involved in the
creation of the world, he is largely, or totally uninvolved in the intricacies of its ongoing existence. This is contrasted with Theism, in which God not only made the world, but sustains its existence. He remains intimately involved with everything that continues to happen in his creation. The contrast is therefore the difference between a watchmaker who made it, wound it up and let it go and a composer who note only wrote all the notes, but also conducts the orchestra.
Some creationists accuse theistic evolution of deism: so, Wayne Grudem writes "The fundamental difference between a biblical view of creation and theistic evolution lies here: the driving force that brings about change and the development of new species in all evolutionary schemes is
randomness.... But the driving force in the development of new organisms according to Scripture is God's
intelligent design." (Systematic theology, 276)
Yet it seems here that Grudem has assumed, a priori, that the view of "randomness" that theistic evolutionists tend to believe in is one that is outside of God's theistic design. Yet
every theist ought to believe that though there are apparently "random" and "chance" events the Lord is utterly sovereign in them all. The Lord has "designed" intentions in them. From the roll of the dice to the decision of free agents the Lord has intentions that are most certainly NOT random.
Proverbs 16 reminds us of both of these facts
9 In his heart a man plans his course,
but the LORD determines his steps.
33 The lot is cast into the lap,
but its every decision is from the LORD. (NIV)
Undoubtedly there are some who hold to theistic evolution who themselves tend towards deism. I have had conversations with people who suggest that God set it up in such a way that he knew
something good would come out of it, but could not be sure
what. So, Deistic Evolution posing as Theistic Evolution exists. But, I fear that it may betray some deistic assumptions on the part of creationists if they will insist that
apparent randomness is incompatible with intelligent divine design.
On the other hand there are those who hold to theistic evolution who accuse creationists of deism.
Ever since Henry Drummond coined the phrase "the god of the gaps" it has been used as an accusation against those who hold to creationism, and more recently Intelligent Design. The idea is that peopl
e seem to think that science runs itself quite nicely, thank you very much, but there are a few things that cannot be explained without some kind of miraculous intervention from God. Like
Drummond, they urge instead belief in "an immanent God, which is the God of Evolution, is infinitely grander than the occasional wonder-worker, who is the God of an old theology."
Well, though once again this accusation of a God only occasionally involved in His world may be fair for a few creationists, sure theistic creationism is also possible: that God is utterly involved in every moment, but differently involved in the miraculous.
Whichever position you take on the Creationism vs. Evolution debate, make sure that in avoiding falling into materialism, you don't inadvertently fall into deism: that would be a far more serious error than getting the Creationism vs Evolution question wrong.
Make sure also that you don't wrongly accuse a brother or sister in Christ who believes in the same God as you do of a theology to which they do not hold.
