There is a conceit embedded in the fact of Jesus' teachings having been taken up by the Western World, that bastion of self-professed logical thinking. Logical thinking is pregnant with the premise that proper thought is step-wise and defensible at every such step, such that any postulate of logic is premised ostensibly on the simple and the unquestionable. This contention is attended, of course, by the irony of the necessary insistence that "life"--that into which we are thrown in the mid-stream tumble of the infant's burgeoning consciousness--is analyzable in terms of pristine starting-points.
This is the realm of the philosophy of the Hellenic-enchanted Paul, not the realm of Jesus. If the teachings of Jesus are ever "simple"--such as our ever-overburdened minds typically desire--they are simple in that they lay out the predicament of human life in straightforward expressions of bewilderment that would follow "logically" from honest assessment of the primordial confusion-state of finite creatures (such confusion being only compounded by the overarching prospect of humanity's position before the ineffable God.) The "logic" of Jesus is the drawing-up of our scooped-together and shakily-held conceits into manifestly imperfect self-awarenesses who struggle forward with the simplicity intrinsic to our plodding through steps--and through simplistic dimensions known roughly by us--even as we are unsettlingly aware that infinities of unappreciated considerations have escaped us.
And then there are the teachings of Paul, with their assiduously-enshrined premises of certainty. So will Paul in Romans tell us that--independent of this or that version of assiduously-transported "gospel"--"that which may be known of God is manifest to them" (that is, to the distant heathen.) And thus, according to Paul--who wields the clumsy cudgel of maintaining that "that which may be known of God" is known by natural expression through Creation--every ascertainable quality of God with its logically-derivable duties of the believer has ever been known, making the dissemination of the Gospel superfluous, and the imperfections of the evangelists sources merely of potential error and confusion.
Jesus brings the simplicity of straightforwardly and repeatedly describing the confusion-state of our predicament before our Creator. Even before Jesus, and especially in the regions distant to any message or even echo of the Bible or Bible-adjacent philosophies, our common human experience tells us that our existence is beyond our grasp--we can never receive too many reminders of our unsettled state. And we as a species have never suffered any lack of "simple and straightforward" (and presumptuous and poisonous) pontifications about ultimate reality and our place in it--whether these pontifications arrive with animal-headed statues and temple prostitutes, or arrive with ancient-Greek-logic-spouting missionaries espousing this or that version of the Cause of Christ.
And, of course, Paul's insistence on basing an expression of Jesus' teachings upon Western logic-loving postulations about what "may be known of God" (rather than upon a more humanly-basic appreciation of the infinity of what may not be known of God) betrays Paul in the end. In that very Book of Romans Paul is driven, as if by the very torturous "goads" of his internalized experiences, to spit out, "To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life. But unto them that are contentious, and do not obey the truth, but obey unrighteousness, indignation and wrath." It has perhaps been fortunate for "faith alone" Protestantism, that the preceding King James quotation (to modern ears) can only with hovering hesitation be parsed out in its true implications--to do well it to gain eternal life, to "obey unrighteousness" is to gain the horrible alternative to eternal life. In Paul's much-celebrated practice of "simple logic," the above quote must stand alone both in its sufficiency, and in its inescapable implications.
And so Paul's ministry is thrice-bedeviled by his enthrallment with the progressions of logic from pristine (and unreal) postulates, rather than from the messy and organic experience-lives that Jesus ratifies in his listeners. "Faith-alone" Protestantism, which finds (more or less) substantial support elsewhere in Paul's writings, is devastated when his simple references to acts deserving damnation are confronted roundly. Jesus' ministry itself, once digested through the maw of Paul's conjured thought-creature of disembodied logic, is rendered lifeless. And lastly Paul's artifices of logic show themselves to be renderings of his own experiences, rather than representations of what a fair observer might believe portray the comprehensive compass of God's eye.
Thus Paul reels off a litany of sinful humanity's misdeeds, "Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers, Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents, Without understanding, covenant breakers, without natural affection, implacable, unmerciful." "Full of envy, murder, debate, deceit, malignity?" In a world of rape, murder, torture, abuse, and the slaughter of conquest, who brackets murder with "envy" and "debate"? One might almost detect in Paul a frantic and implacable urge to measure his history of sending innocents off to be killed as merely a prior overblown enthusiasm with theological wrangling. Indeed, it is amazing how many of the listed misdeeds above can represent irritants to self-righteous and self-centered (to say nothing of self-interested) participants in debate. These listed irritants, along with more than a few very general references ("without understanding," "without natural affection," and the like) come across as more representative of Paul's dismay at the louts with which he had to argue, than of God's observations in Scripture of humanity's depravity.
And there is yet more to consider. These complaints from Paul are preceded in his Romans with the infamous imprecations, ". . . God gave them up unto vile affections: for even their women did change the natural use into that which is against nature: And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly . . ." This is not supposed to be an Acts-type story of Paul stumbling into some real-life milieu in which he was confronted by displays of what he would be bound to consider "unseemly"--this is supposed to be an inspiration-prompted condemnation of how humanity really is. How much might the lot of history have been lightened if the Holy Bible, armed with the voice of Paul, had called out sexual misdeeds as might the voice of God? How many children might have been spared, or others unable to give consent, or yet others--slaves, and oppressed persons and the poor, and disempowered spouses?
Yet what we have, in Paul's celebrated dissection of the morals of a humanity that has disregarded its Maker, not a God's-eye revulsion with the panoply of our evils, but precisely what we would expect from a Paul disgusted--and I say not that he had no reasons to be disgusted--but a Paul disgusted with the persons and classes with which he clashed--with people who had worked out for themselves their own internally-defensible belief systems, and who had fashioned for themselves justifications of whatever they came to believe themselves entitled to lay their hands to. People--or at least many of them--who had nice, simple, defensible-on-their-own-terms logical schemes likely as impressive as those of Paul.
Next we must compare those schemes with the utterly different approach of Jesus--the approach in which it is understood that logic itself is a product of an insubstantial scheme--the approach wherein our steps slip away beneath us even as our premises disappear behind us.
