Beyond the major and minor arguments of the body of the work, come those that are more or less speculative. These are widely contested, and do not stand as doctrinal points, but, as merely informed opinion. They may be right, and they should be right, yet, since they cannot be supported fully and only by Scripture, the only true authority for any work, they must be categorized as separate.
Indeed, many speculations may disolve into nothing, or, instead, they may even develop further into minor and even major arguments. Most, in fact, of the major arguments, one fully unsupported by the text, have proven themselves faithful through study. In such a way, the shape of the whole is formed. At some point, this becomes less often, however, the progression of a speculation into a minor argument should be expected, so long as it is not completely revelatory.
Since these are merely based upon the faith of the individual, and not the full body of text, no argumentative stance should be adopted concerning these. They are Beyond the revealed word, and may be believed and even discussed among the mature, but they are not to ever be insisted upon as truth, so long as it is not directly, emphatically, and primarily enforced through scripture.
Keep the main thing the main thing, and keep the essentials as the essentials. In this way, you will keep the reproach off of the body, whether you are right or wrong, and you will keep the reproach off of yourself, because you stand only upon, “It is written”. The Word is enough. Let the Word be what it is, and yet still allow for revelation. Yet, never substitute the one for the other.
