“Where was your Church before Aquinas”
Ever since the Reformation, Roman Catholics have been fond of asking, “Where was your Church before the Reformation”. Protestants have a good reply to that: “Where was your Church before Aquinas”.
Peter Lombard (in his “Sentences”) summarized church teaching up to that point (approximately 1150). Aquinas later opposed Lombard on one key point (“justification extra nos”, or the external righteousness of Christ), and Luther took up Lombard’s side:
In book 1, Distinction 17 of his famed Sentences, Lombard, discussing religious justification, asked: “Is the love by which we are saved a created habit in our soul, or is it the very person of the Holy Spirit dwelling within us?” Is that which heals and saves a person part of his own nature, something he himself has developed as his own possession [inherent righteousness], or is it the indwelling spirit of God, a divine power in him but not of him [alien righteousness]?
Lombard opted for the latter solution, maintaining that the love by which people love God and their fellow man so as to merit salvation [“merit” being a whole ’nother story] was the spirit of God working internally, without their aid or volition. Man is saved by an uncreated, not a created habit, by uncreated, not created, love, by the holy spirit within, not by an acquired talent he can call his very own. When the young Luther wrote hs commentary on the Sentences in 1509/10, he strongly agreed, against the majority of scholastics, with this interpretation by Lombard.
Thomas Aquinas opposed Lombard in this issue, arguing that saving charity [“charity” being “love” in the Roman Catholic schema] must be a voluntary act arising from a disposition man could call his own.
Roman Catholics claim that Martin Luther was the innovator, but in reality, Thomas Aquinas was a far more extensive innovator than Luther ever was. The problem was, “The Church of Rome” liked what Aquinas had to say, and they canonized it.
The Reformers sought to roll back many of the changes that Aquinas put into place. And in doing so, they relied on earlier traditions than did Aquinas.
It was Aquinas who not only introduced Aristotle to the Roman church, but he wrapped Aristotelian philosophy around Christian doctrine and handed it to “the Church” as a complete package. One that supported the Roman Church’s view of its own authority and necessity.
