Our beliefs about God should never be confused with God. Our beliefs and doctrines may point us to God, teach us something about God, anchor us to the truth, or show us God in a different light, but they are not in themselves God.
When we elevate our beliefs about God to the level of God Himself we forge idols out of our own opinions, we carve images out of logical propositions, and we become priests who hold the keys to heaven and hell, salvation and damnation.
This is a dangerous place to be. When we start pronouncing who’s “in” and “out” of the kingdom of God because of their views on things like Creationism vs. Evolution, Calvinism vs. Arminianism, Rebublicans vs. Democrats, or even the role of women in the church and home, we are treading on dangerous ground, for we have elevated tertiary things to the level of ultimacy.
True worship acknowledges that our beliefs about God are but murky shadows next to the reality of His light. Valuable as doctrine is, it cannot compare with the grandeur of Jesus Christ. Wonderful as theological speculation may be, it pales next to the God who stands outside of human reason and refuses to be harnessed by our limited understanding.
And, yes, even theology can become an idol.
