Jesus and the apostles used it (Scripture) and derived further conclusions from it through reasoning...

After all, the Scripture was not given to us merely to be repeated but to be pondered and expressed in our own language; Jesus and the apostles used it and derived further conclusions from it through reasoning; the Scripture is not a legal code or a systematic theology but the principium of theology; as the Word of God, it binds us not only in its literal words but also in what is legitimately deduced from it. Moreover, no reflection on the truth of Scripture and therefore no theological activity is possible without using such words that do not occur in Scripture. Not only in the doctrine of the Trinity but also every other dogma and in the entire field of theology, expressions and terms are used that are not found in Scripture. With these names, therefore, the autonomy of the Christian, the right of theology, is involved. And finally, these do not serve to introduce new dogmas outside of Scripture or in conflict with it but precisely to maintain the truth of Scripture against heresy. They have much more negative than positive significance. They indicate the lines within which Christian thought must move in order not to lose the truth of revelation at the hands of heresy.

Herman Bavinck (1854-1921)

The Holy Trinity (1895)

Such a posture should not be surprising, nor considered as lowering Scripture's status, rather quite the opposite; unsurprising then elevating. Quite aligned with traditional Logic as the Science of Sciences, if to understand the aforesaid as merely the study then fine-tuning of the mind's innate even unavoidable abilities and propensities. To compare, the athlete does not study and train so to learn the method of running, rather to improve and perfect (as humanly possible) his/her natural yet unrefined ability to run; so it is with the study of Logic.

With that said, Bavinck implies hence proposes Scripture as Primary Source provided and revealed by God the Creator of all creation thereby First Cause of all causes and effects. In this way, Scripture is not reduced to humanity's considerations, rather elevated not to a higher status but the highest regard and reverence from which to deduce then induce, in a word; ratiocination. Accordingly, at least since Aristotle's work on Logic entitled Organon, inquirers and researchers of all sorts of disciplines, including logicians especially, have emphasized the consistent determinations of names, definitions, then categories, later organized per the Porphyrian Tree or the Tree of Porphyry, and later still as genera and species.

When fire and the wheel were first utilized, invented, and later studied, words like incandescent, luminous, else cylindrical, ambulatory were not initially named, defined, then categorized, yet no less applicable and accurate their longstanding associations and representations. So it is with doctrinal words like Trinity that have been long deduced then induced from Scripture as the Primary Source resulting from the First Cause, subsequently then consistently named, defined, and categorized.

Come let us Reason. Peace is always a Choice.
