Summa Theologica
Summa Theologica is a book by Thomas Aquinas, written from 1265 through 1273. Among Catholics it is often considered to be the most perfect and complete summary of Christian theology. Aquinas applied Aristotelian philosophy to Catholic theology to outline a philosophical framework supporting Catholic belief.[1]
Written in the last dozen years of Thomas Aquinas's life, it fills about 3,000 pages of double-columned pages and is considered one of the most influential works in Western civilization. It is vast in length: 1.8 million words, comprised of 512 Questions, 2,669 Articles, and roughly 10,000 objections and replies.
The Summa Theologica led Thomas Aquinas to a spectacular personal revelation during a Mass, which caused him to stop writing altogether, and he died three months later without completing this masterpiece.
