Is “Theory” the Right Word?

On occasion, someone will criticize my use of the word “Theory”, presumably on the grounds that any proper theory must be falsifiable.  This objection always surprises me, however, since I researched the word before using it in my title, and found no such requirement.  I have listed several dictionary definitions below—more than enough to establish that no such strict definition of the word is necessitated in English usage.

One definition, buried deep within Wikipedia’s article on “Theory”, requires falsifiability in scientific theories:

From Wikipedia.com
In science, the term “theory” refers to “a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.”[11][12] Theories must also meet further requirements, such as the ability to make falsifiable predictions with consistent accuracy across a broad area of scientific inquiry, and production of strong evidence in favor of the theory from multiple independent sources.

Obviously, the Temporary Ekklesia Theory is not scientific in nature.  Interestingly, however, it does seem to qualify as theory with regard to the Wikipedia sentence that follows the section pasted above:

The strength of a scientific theory is related to the diversity of phenomena it can explain, which is measured by its ability to make falsifiable predictions with respect to those phenomena.

TET makes several predictions, which I have listed in another article.  Should these predictions prove false, then TET would thus be falsified.

It should be noted that the Temporary Ekklesia Theory is an interpretive theory of the Bible, which can most certainly be falsified by rational proofs that such interpretation is logically, factually, and/or linguistically untenable.  For example, if it were proven that the Greek word “ekklesia” contains a root that mandates permanency upon the earth, this would irreconcilably undermine the Temporary Ekklesia Theory.  Or, alternatively, if someone were to produce a passage from scripture that prophesied that the ekklesia would remain perpetually upon the earth, that also would falsify the TET.

Here are entries for “theory” from several dictionaries.

1. A set of statements or principles devised to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena.
2. The branch of a science or art consisting of its explanatory statements, accepted principles, and methods of analysis, as opposed to practice: a fine musician who had never studied theory.
3. A set of theorems that constitute a systematic view of a branch of mathematics.
