Martin Luther, as I have referred to previously, was indeed anti-Aristotelian, particularly with reference to Aristotle’s anthropology as that effused throughout his Nicomachean 
Ethics. Indeed, Luther makes his disgust toward Aristotle’s Ethics, and thus, anthropology, very clear in his theological protestations, as he nailed those, just a month prior to his 95 theses, to the Wittenberg door. This was the real reason for Luther’s reformation, as my former professor and mentor, Dr Ron Frost, has so clearly argued. Luther saw Pelagian wickedness in Aristotle’s anthropology, and of course insofar as Aquinas appropriated Aristotle’s Ethics, among other things, this compelled Luther to post his Disputation Against Scholastic Theology contra the Papacy. When you read his DAST it is clear that Luther sees the anthropology forwarded by Aristotle as a corrosive agitant vis-à-vis an orthodox, and thus biblical understanding of salvation. Here is the aspect where Luther makes clear, in 1517, what he thinks about Aristotle’s impact upon the Papal doctrina:
- We do not become righteous by doing righteous deeds but, having been made righteous, we do righteous deeds. This in opposition to the philosophers.
- Virtually the entire Ethics of Aristotle is the worst enemy of grace. This is in opposition to the scholastics.
- It is an error to maintain that Aristotle’s statement concerning happiness does not contradict Catholic doctrine. This is in opposition to the doctrine on morals.
- It is an error to say that no man can become a theologian without Aristotle. This is in opposition to common opinion.
- Indeed, no one can become a theologian unless he becomes one without Aristotle.
- To state that a theologian who is not a logician is a monstrous heretic–this is a monstrous and heretical statement. This is in opposition to common opinion.
- In vain does one fashion a logic of faith, a substitution brought about without regard for limit and measure. This is in opposition to the new dialecticians.
- No syllogistic form is valid when applied to divine terms. This is in opposition to the Cardinal [Peter of Ailly].
- Nevertheless it does not for that reason follow that the truth of the doctrine of the Trinity contradicts syllogistic forms. This is in opposition to the same new dialecticians and to the Cardinal.
- If a syllogistic form of reasoning holds in divine matters, then a doctrine of the trinity is demonstrable and not the object of faith.
- Briefly, the whole Aristotle is to theology as darkness is to light. This is in opposition to the scholastics.
- It is very doubtful whether the Latins comprehended the correct meaning of Aristotle.
- It would have been better for the church if Porphyry with his universals had not been born for the use of theologians.
- Even the more useful definitions of Aristotle seem to beg the question.[1]
This poses a problem, especially to those desirous of retrieving Post Reformed orthodox theology for the renewal of the 21st evangelical and Protestant churches. David Sytsma has recently argued that the later Luther came to find Aristotle’s Ethics useful, at least in some way, but that even if he didn’t (which he didn’t, in the main) Luther is really of no consequence to the development of Protestant theology; that Luther’s impulses were not necessary for the flowering of a latterly developed Protestant orthodoxy. Indeed, Sytsma wants to recast the foundation for the development of Protestant orthodoxy at the feet of Luther’s codifier, Philip Melanchthon. Sytsma writes:
Despite Luther’s early polemic against Aristotle, he did not altogether reject the usefulness of the Nicomachean Ethics. Just as Melanchthon had joined Luther in his initial critique of Aristotle, there are indications that the influence went the other way as well. In his later years, after Melanchthon had reintroduced Aristotle’s ethics at Wittenberg, Luther expressed remarkable appreciation for Aristotle’s text. In 1543, Luther said that although philosophers such as Cicero and Aristotle do not teach “how I can be free from sins, death, and hell,” they nonetheless wrote excellently on ethics: “Cicero wrote and taught excellently about virtues, prudence, temperance, and the rest. Aristotle similarly also [wrote and taught] excellently and very learnedly about ethics. Indeed, the books of both are very useful and of the highest necessity for the conduct of this life.” (Luther 1930: 608) Luther also appropriated Aristotle’s concept of equity (epieikeia) from book V of the Nicomachean Ethics as a consistent part of his theology (Kim 2011: 91-98; Gehrke 2014; Arnold 1999). In his Lectures on Genesis wrote that “peace and love are the moderator and administrator of all virtues and laws, as Aristotle beautifully says about epieikeia in the fifth book of his Ethics” (Luther 1960: 340; Kim 2011: 94). Alongside his praise for Aristotle’s concept of epieikeia, Luther even affirmed Aristotle’s concept of virtue as a mean between extremes:
Aristotle deals with these matters in a very fine way when he writes about geometrical proportion and epieikeia…. The law must be kept, but in such a way that the government has in its hand a geometrical proportion, or a middle course and epieikeia. For virtue is a quality that revolves about a middle course, as a wise man will determine. (Luther 1966a: 174; Gehrke 2014: 90)
Such remarks indicate that while Luther initially objected to perceived theological abuse of Aristotle’s ethics, he came to accept its usefulness in certain respects (Gerrish 1962: 34-35). Whether or not this is the case, however, Luther’s own views are not definitive for the larger history of Protestantism, for his early anti-Aristotelian polemic was not taken too seriously by later ethicists at Protestant universities, who on this matter “looked for guidance from Melanchthon rather than Luther” (Svensson 2020: 189).[2]
It is interesting as we read Sytsma what becomes rather apparent is the type of hedging, he is engaging in throughout his treatment. The way we know he is hedging is the way he concludes: viz. that Luther’s thinking is ultimately of no consequence towards the later development of Protestant orthodoxy. I say he is hedging because you can sense a level of ‘spin’ in regard to the way Sytsma is attempting to present Luther vis-à-vis Aristotle. There is no doubt that Luther appreciated certain aspects of Aristotle’s ability to communicate with a level of technical precision and clarity that would make any communicator and teacher swoon. But there is scant evidence to suggest that Luther ever recanted of what he intentionally wrote contra Aristotle’s Ethics in his Disputation Against Scholastic Theology. For Luther the whole premise of his reformational work was bounded by his slavish commitment to what came to be his seminal and paradigmatic moment; his realization of sola fide, ‘Faith Alone!’ Aristotle’s anthropology was diametrically opposed to this reality, insofar that his notion that humanity had a capacity within itself to be virtuous through habituation in the virtues, ran counter to Luther’s commitment to the Bondage of the Will. When you read the whole of Luther’s DAST, this becomes the clear target of his protesting, and thus reformational identity. To attempt to soften this, in regard to Luther’s “later” stance towards Aristotle, is to play fast and loose with the historical Luther in context; Sytsma should know better. He does, in the end, know better, and knows he must admit that Luther’s reformational impulses run counter to the type of ‘Christian Aristotelianism’ (see Muller) that he is attempting to recover for a 21st century Protestant revival of orthodoxy.
Why does this historical matter, matter, though? It matters because the truth matters, for one thing. Beyond that, at a material theological level it matters because as Protestants we want to be committed to, indeed, a faith alone mode as our evangelical identity. Luther’s protest was contra a system of soteriology that saw grace as a substance presented through the liturgy of the Holy Roman Catholic See. He understood that the only Mediator between God and man, was the Man, Christ Jesus. As such, to attempt to sneak a concept of grace back into the Protestant theological matrix that is funded by an Aristotelian anthropology dead-set against this type of immediate mediation between God and humanity through Christ Jesus, is to undercut the whole premise of what it originally meant to Protestant. If Sytsma and the whole machine he works within desires to think grace and salvation in the terms provided for by Aristotle, then do what so many Presbyterians, and the like have done in recent years, and swim the river Tiber; but don’t pretend to call yourselves ‘Protestant’ simply because the Post Reformed orthodox almost immediately fell right back into the communal waters of the Papal font. So-called Post Reformed orthodoxy is an anachronism constructed in order to identify the development of Protestant Reformed (and even Lutheran) orthodoxy that took place in the 16th and 17th centuries. But according to the Protestant ‘Scripture Principle’ Protestants don’t operate with a magisterium of the sort that Sytsma et al. are attempting to set this period of Protestant doctrinal development up as. We don’t allow nostalgia of a Western European development, even if it is ostensibly “Protestant” to allow it to call us into siren soundings, and blind us to what is actually at stake in regard to Protestant, and more importantly, biblical doctrina. And yet I would contend this is exactly what Sytsma and his whole company have been drawn to.
Luther would be rolling in his grave if he knew what happened to the Protestant churches. But no matter, as Sytsma would say to Luther: “[your] views are not definitive for the larger history of Protestantism. . . .”
