Presuppositions: To suppose beforehand. Something which you presume to be true before you enter into a study. The evolutionist presupposes that the Biblical account of creation is false, and presumes to know what they believe is truth.
In electronics there is a basic presupposition which the whole of television, radio, computer etc. is based. The presupposition is the fact that there is an electron flow through a substance. In a light bulb you must suppose that the electrons are flowing to explain the whole system of electricity and electronics. Without this supposition you have nothing, for you cannot prove there is an electron flow. For many years they supposed that electricity flowed from negative to positive.
We will have some presuppositions before we finish with the Prolegomena that will be used in our study of theology.
Dogma: No, this term does not mean your dog’s mother. It means according to Webster, “something held as an established opinion.”
Dogmatics: A study of things that can be held with all certainty. Some examples of dogmatics: Christ is God. Christ died, but rose again. These are dogmas of Christianity in general. (This is why the Roman Catholic Church is considered to be within the realm of Christianity.)
We don’t use the term much in fundamental circles, probably because it is a term that the Roman Catholic Church and some Lutherans use extensively. Our non-use of the term may relate to the fact there aren’t many things that evangelical Christianity holds as sure and certain. Many of the doctrines of the past have suffered and now are not certainties. Doctrines such as the pretribulational rapture, the premillennial return of Christ, the blood of Christ, and the two natures of man. We might be quick to add that some of these certainties were based on less than adequate study and evidence. There is evidence now that the “two natures of man” doctrine may not be technically correct. For the most part, however the lack of certainty is based on a lack of study rather than the certainty itself. The blood of Christ and His return are quite sure, as is the rapture.
Theology: This term comes from two terms — “theos” meaning God and “logos” meaning “rational expression” (Reprinted by permission: Ryrie, Charles C.; “Basic Theology”; Wheaton: Victor Books, 1986, p 13) In short, the rational expression of God. The study and expression of God, if you please.
Ryrie lists three elements in theology:
1. Theology can be understood by the human mind.
2. Theology requires explanation; thus one must study and systematize it to verbalize theology.
3. Theology is Bible based and thus theology will result from Bible study. “Theology, then, is the discovery, systematizing, and presentation of the truths about God.” (Reprinted by permission: Ryrie, Charles C.; “Basic Theology”; Wheaton: Victor Books, 1986, p 13)
“Its aim is the ascertainment of the facts concerning God and the relations between God and the universe, and the exhibition of these facts in their rational unity, as connected parts of a formulated and organic system of truth.” (Taken from the book, Christian Theology by Emery H. Bancroft. Second revised edition Copyright 1976 by Baptist Bible College. Used by permission of Zondervan Publishing House. p 13)
Theology can be classified in many ways: It can be classified by false and true. It can be classified by time frame: Early Church, reformation, modern etc. It can be classified by view: Calvinist, Armenian, liberal, evangelical, fundamental, etc.
