Philosophy is a walk on the slippery rocks.
Religion is a light in the fog.
-- Edie Brickell and the New Bohemians
So is theology more like philosophy or religion? Is it a walk on slippery rocks or a light in the fog? Is it the philosophies of men, mingled with scripture, or a reasoned inquiry seeking the principles that define spiritual truth? For an LDS view on this interesting question, go read the EOM article "Theology," authored by Louis C. Midgley, this week's online essay.
To get you started, here's the first paragraph:
The traditional task of theology (from the Greek theos, God, and logos, study of) is to seek understanding of God's reality, to describe divine things rationally, and to elaborate the present meaning of past manifestations of God, whether theoretically, practically, descriptively, or critically. Since scriptures and specific revelations supply Latter-day Saints with authoritative answers to many of the traditional concerns of faith, members of the Church tend to devote little energy to theoretical, speculative, or systematic theology. For Latter-day Saints, faith is anchored in revelations that occurred in history. From the perspective of the restored gospel, what can be known about divine things must be revealed by God. Though rationally structured, coherent, and ordered, the content of Latter-day Saint faith is not the fruit of speculation, nor has it been deduced from premises or derived from philosophical or scientific inquiries into the nature of things.
