Aristotle -> Aquinas -> Atheism, Part 8
To wrap up some loose ends, the aformentioned proofs aren’t the end of proving the attributes of God. The scholastics had many proofs and reasons for his various attributes. Aquinas only touches on a few because at this particular point in his work he is trying to focus upon the causes outlined by Aristotle. One would need to look at the total of the Summa Theologica for the total of his proofs for the various attributes of God.
It would be hard to understate the impact Aristotle had on Church thinking. Taking just one theological point as an example: the causes of justification. The council of Trent (1945-63) listed five causes of Justification. The final cause, the efficient cause, the meritorious cause, the instrumental cause, and the formal cause. Aristotle’s causes are all but the meritorious one.
On a side note of history, the sole formal cause of justification is grace. One of the rallying points of the early Protestants was Sola Gratia (a.k.a., Grace Alone) which Trent affirmed in its’ statement on the formal cause of grace.
