Saint Thomas Aquinas: Sacra Doctrina vs Sola Scriptura Part I

Saint Thomas Aquinas: Sacra Doctrina vs Sola Scriptura Part I
Matthew J Bellisario O.P.


                Revision 2019
                In the Dominican spirit I have resurrected this article which I wrote almost 10 years ago as a refutation to several Protestant apologists who were claiming that Saint Thomas Aquinas held to a type of Sola Scriptura similar to theirs. In reading their arguments it was very apparent that they were guilty of quoting Thomas out of context. Unfamiliar with his corpus of work and their historical setting they misinterpret many of the phrases and terms he used. I have gone through and edited the original article for clarity. Although this article was originally written as an apologetic work, I believe it will also be of benefit to Catholics who want to know more about how Saint Thomas viewed Sacred Scripture in relation to Sacred Tradition and the Church.


            Introduction
Saint Thomas Aquinas is one of the greatest Latin theologians the Church has ever produced. There have been attempts by those outside the Church such as William Webster, who I will address later, to brand him as some type of pre-Protestant theologian, subscribing him to a form of “Scripture Alone” theology. "The Scriptures held a place of supreme authority in the Church. In a quotation previously referenced, Aquinas echoed the sentiments of Basil of Caesarea and Augustine, stating that the teaching of the fathers was received as authoritative only when it could be demonstrated that it was true to Scripture. He taught that Scripture alone was the canonical standard of doctrine, and therefore the foundation and source of truth for the faith of the Church: 'Only canonical Scripture is the rule of faith'.”[1]
Although some passages taken in isolation may at first glance appear to put him in such a category, more extensive reading of Thomas’ material along with proper interpretation will prove him to be much in line with traditional Catholic theology as St. Augustine and St. Basil were, which subscribes to the Scriptures as being God’s written Word, being of the same substance of His Oral Word, as taught and proclaimed infallibly by Holy Catholic Church. The Catholic Church teaches that the Church is not above God’s Word, but only serves it and proclaims its proper interpretation. As we will see, Saint Thomas thought the same. In fact, Saint Thomas did not view any of these elements as being separate entities. In fact, they all fit together almost as the Holy Trinity fit together in one divine substance. Just as the Father, Son, and Holy Spirit cannot ever be separated, so the Eternal Word proclaimed in Scripture and Tradition, as taught infallibly by the Holy Spirit through Christ’s only Church, cannot be separated. Before we begin to examine Saint Thomas’ writings, we must first understand Saint Thomas’ educational and historical background.

Saint Thomas' Historical Background
Saint Thomas began his formal studies at Montecassino in Italy. The education he received there was a form of scholastic, classical curriculum that focused on the trivium and the quadrivium. Saint Thomas was well versed in logic, rhetoric, grammar, arithmetic, geometry, astronomy and music, which he continued to study when he was later, sent to Naples, Italy. It was however in Paris and Cologne where he received his formal theological education. It is here that we can find the roots of his theological positions. Peter Lombard’s work titled the Sentences, was very popular at the time. Saint Thomas studied Peter Lombard and was very familiar with the scholar’s theological works. In fact, Saint Thomas composed a commentary on his work titled ‘The Sentences’, which if left unabridged would span a 6000-page volume work in today's average book format. Lombard’s was a foundation from which Saint Thomas built upon, yet he was never afraid to modify or change directions in his own theological work. Saint Thomas would later use the works of Lombard to defend Catholic teaching for Pope Urban IV against the errors of the Eastern Orthodox. Saint Thomas was also a formidable Patristic scholar to which he frequently deferred to substantiate his Biblical exegesis. Despite his appreciation and study of the Fathers, he was in many ways an innovator in regards to Scriptural scholarship.
What many people today, however, may not understand is the focus of studies among the universities of his time. The theological focus of the medieval universities of Saint Thomas’ time, were devoted primarily to Biblical studies. Saint Thomas, being a professor twice in Paris, was no exception, and his theological work is in large part focused on Biblical scholarship. Much of his work was not composed as a complete defense of Catholic doctrine in a strict sense, it was developed in a large part to examine and cultivate the literal sense of Scripture. We must note that the word literal here is not synonymous with today's fundamentalist definition. We will touch on that later in this work.
There are also a few basic historical facts that we should remember when reading Saint Thomas. Although Aristotelian philosophy had already influenced great theologians like St. Albert, one of Thomas' teachers, we should remember that Saint Thomas was one of the first Latin theologians of the middle ages to really expound upon and integrate the sound aspects of Aristotelian philosophy with theology. It influenced how he viewed Sacred Scripture, and it developed in him a profound leaning towards the sufficiency of the literal sense of the Scriptures, which almost seems contrary to many of the Church Fathers who came before him, who tended to emphasize the spiritual senses over the literal. Although theologians such as Saint Augustine wrote about understanding Scripture in the literal sense (De Doctrina Christiana), none emphasized the sufficiency of the literal sense as Saint Thomas. Catholic theologian Matthew Lamb writes, “St. Thomas' unqualified adoption of the Aristotelian doctrine concerning the dependence of the human mind on the imagination threw a new light on the importance of the literal sense of Scripture.”[2] This difference was largely due to the influence of Platonic philosophy on the earlier theologians that came before Saint Thomas. 
Saint Thomas developed his theology primarily through his studies on St. Augustine. Saint Thomas leaned on the literal sense of Scripture to combat heresies of the day such as the Cathar heresy, who developed their heresies by rendering a false “spiritual” sense in place of the literal. It was Saint Thomas’ position that the literal sense of Scripture was the only sense on which strict theological arguments should be based on in regard to Scripture itself. Hence we see him address this issue in his Summa Theologiae, “Consequently Holy Scripture sets up no confusion since all meanings are based on one, namely, the literal sense. From this alone can arguments be drawn, and not, as St. Augustine mentions in his letter to Vincent the Donatist, from whatever is said according to allegory. Nor is anything lost from Sacred Scripture on this account, for nothing that is necessary to faith is contained under the spiritual sense which is not openly conveyed by the literal sense elsewhere.”[3] Saint Thomas here clearly states his opinion as to how Scripture teaches matters necessary to the faith. He proposes that when Scripture teaches something necessary to the faith, it does so in the literal sense. This emphasis on Scriptural interpretation was developed by Saint Thomas and it influenced much of his work.
It must be understood that Saint Thomas never separated the Scriptures from the Tradition of the Church. He demonstrates his belief in the primacy of the Church of Rome, which was founded upon Saint Peter. "This is as if He said: "They shall make war against thee, but they shall not overcome thee." And thus it is that only the Church of Peter was always firm in faith. On the contrary, in other parts of the world there is either no faith at all or faith mixed with many errors. The Church of Peter flourishes in faith and is free from error. This, however, is not to be wondered at, for the Lord has said to Peter: "But I have prayed for thee, that thy faith fail not; and thou, being once converted, confirm thy brethren."[4]
As stated earlier Thomas used the writings of the Church Fathers to arrive at proper Biblical interpretations of Scripture. It is a fact that Urban IV requested him to compose a gloss on the four gospels, in which St. Thomas referred back to the original Greek sources to compose. It is a topic of debate as to how well versed St. Thomas was in Greek, but it is apparent that he at least possessed some understanding of the language. It is also well known that he referred to other Greek scholars of his day, to which he used their translations of the Greek Father's original texts to compose much of his work. Most people are familiar with his gloss often titled “the Catena Aurea.” In it, he cites 22 Latin Fathers and 57 Greek Fathers all of which were cited to support the Church’s traditional interpretation of the Scriptures regarding proper doctrinal teaching. Although Saint Thomas is often accused of being a Latin minded theologian, the Eastern Church had a great influence on his writings.
It must be noted that although much of Saint Thomas’ work was devoted to Scripture, he does occasionally demonstrate the necessity to appeal to Tradition. Saint Thomas does this when he defends the Catholic Church for Pope Urban IV against the schismatic Church of the East. In his university setting, however, we rarely see Saint Thomas engage in this type of apologetic. His university work falls in line with the Biblical studies, which were the point of theological focus of the time. Nevertheless, Saint Thomas often speaks of the Scriptures as being the “rule of faith”, and when Saint Thomas speaks of the sufficiency of Scripture as a rule of faith, it must be understood that he does not mean Scripture alone, as a Protestant would much later define it. It means the Word of God as expressed in the Written Word and the Oral Kerygma of the Church, within the structure of the Church of Rome headed by the Roman Pontiff.
It appears that Thomas uses these authorities almost interchangeable when referring to Sacra Doctrina. James A. Weisheipl, O.P. of the Pontifical Institute of Mediaeval Studies explains further, “This sola scriptura of which St. Thomas speaks is far different from the sola scriptura (“only the Bible”) of the Reformers. This battle cry was made famous by Luther, who insisted that what is not contained in the Bible is not “of faith.” But Luther and Thomas (or any other medieval theologian) meant two different things by the word Bible, or Sacred Scriptures. For Luther and the Reformers the Bible was thought of as a finished, edited, and (by then) printed collection, while Thomas and the medieval theologians meant the Sacred Word together with the gloss of the Fathers, liturgy, and the living Church.”[5] The final point of Dr. Weishepl is very crucial to understanding these texts of Saint Thomas. It must not be forgotten that St. Thomas did not divorce the living Church, the tradition of the Church Fathers or the integration of the Scriptures in liturgy from the Scriptures themselves as a rule of faith. That living element is what is referred to as Sacred Tradition.
This puts Saint Thomas in good company with modern Catholic theologians such as Pope Benedict XVI. Pope Benedict XVI writes the following on Tradition, “Tradition is indeed never a simple and anonymous handing on of teaching, but is linked to a person, is a living word, that has its concrete reality in faith.”[6] This living element, rooted firmly in faith and Tradition cannot be separated from Thomas' view of Sacred Scripture. Such terms that are used today in modern Protestant works such as “material sufficiency”, “formal sufficiency” and the like, have no place in the thought of the Angelic Doctor. To force these types of definitions upon his writings and thought is an anachronistic error of the gravest proportion to which many Protestant apologists fall into today.


Aquinas’ Sacra Doctrina
At the beginning of the Summa Theologiae St. Thomas opens with how he views Sacred Doctrine, or Sacra Doctrina. There is more than meets the eye when it comes to this term in the mind of Saint Thomas. The term at face value appears to mean nothing more than Sacred Doctrine. Protestants have tried to make this term synonymous with Sacred Scripture, but this is not at all the author’s meaning of the term. Sacra Doctrina was defined and understood to mean sacred instruction, most often in the active sense, but not limited to the active sense. We also cannot forget that sacred doctrine, was a doctrine that was preached or learned as science. For Thomas, the science of Sacra Doctrina was not limited to Sacred Scripture, but the receiving of God's entire revelation through His revealed Word, as well as what was revealed in nature.
In the First Part of the Summa Theologiae, Question 1, Article Two, Thomas offers us some clarification. For Thomas, the doctrina was the foundation of everything he would build the Summa upon. In his third reply to objection two, regarding whether Sacra Doctrina is indeed a science he writes, “Individual facts are treated of in sacred doctrine, not because it is concerned with them principally, but they are introduced rather both as examples to be followed in our lives (as in moral sciences) and in order to establish the authority of those men through whom the divine revelation, on which this sacred scripture or doctrine is based, has come down to us.”[7] Here he reveals a few important facts. First, he reveals that Sacra Doctrina is founded upon the authority of the apostles and that all doctrina and scripture is handed on by this authority. It is this living foundation that all doctrina rests upon, and it is this living foundation which the doctrina is handed on to us including Sacra Scriptura. In other words, St. Thomas here in the opening of his Summa is saying that all doctrina is built upon the foundation and authority of the apostles, not Scripture alone. He clearly points out that all doctrine falls under the authority of the apostles and he states that Scripture is also founded upon that authority.
This foundation that St. Thomas lays down is critical to understand if we are to make any sense out of the rest of the Summa. It must be noted that if one does not understand the opening articles of the Summa, one will never understand the rest of its contents. St. Thomas, as with all the scholars of his time, do not repeat themselves often, and if you miss important points as they are set up in the progression of the Summa, you will not be able to grasp what the author intends to communicate later, no matter how well you read English, or how great of a Latin scholar you are. For Thomas, Scripture and Doctrina were part of the revealed Revelation of God which were given by Christ and the authority of the apostles which St. Thomas clearly states has been handed down through the ages by the Church.
We must note that for Saint Thomas, there is no distinction between Scripture and doctrine per se. For him, doctrina and scriptura were derivative of the same source of all divine revelation, which is God.[8] The distinction between forms of revelation did not need to be made in Thomas's time as would later have to be done after the Protestant revolt. The Protesters of the 16th century actively sought to separate Scripture from its unitive bond with all divine revelation. None of this was a point of focus for Saint Thomas in the theological works of his time. His works were written for the audience of his time, not ours. This is often a mistake people make in reading into the Fathers of the Church. They often mistake the ancient writers as writing for the controversies of the modern-day, removed centuries from the writer’s time. It is this mentality that has sought to apply the Protestant definition of Sola Scriptura to the Angelic Doctor, and it is an erroneous one.
Another historical reality that also illustrates the fallacy of Aquinas as holding to the Protestant heresy of Sola Scriptura is by viewing his relationship and influence with the papacy itself. His relations with Pope Urban IV and Pope Gregory X is well documented. Pope Urban IV requested him to write a defense of the Latin Church and Pope Gregory X was so impressed with Saint Thomas that he personally requested him to attend the deliberations at Lyons in 1274. But as we know, before Saint Thomas could finish his trip to Lyons, he received his eternal reward with the Cistercian monks at Fossa Nuova. It is interesting to note some of his final words in his last hours, for it summarizes his allegiance to the Holy See, and puts to rest any doubt as to his acknowledgment of the Catholic Church's authority. Near the point of his death, he submitted all of his writings to the authority of Holy Mother Church. “Neither do I wish to be obstinate in my opinions, but if I have written anything erroneous concerning this sacrament or other matters, I submit all to the judgment and correction of the Holy Roman Church, in whose obedience I now pass from this life."
