Summa Theologica


St. Thomas Aquinas (1225-1274)

In the 13th century, St. Thomas Aquinas brought together the wisdom of the ancients and the truth of divine revelation to compose the Summa Theologica.  Pope Leo XIII said,

“The chief and special glory of Thomas, one which he has shared with none of the Catholic Doctors, is that the Fathers of Trent made it part of the order of conclave to lay upon the altar, together with sacred Scripture and the decrees of the supreme Pontiffs, the Summa of Thomas Aquinas, whence to seek counsel, reason, and inspiration.”

While the wisdom it contains was called “miraculous”, “angelic” and “golden”, St. Thomas intended the work to be studied by all believers–including beginners.  He said,

“We purpose in this book to treat of whatever belongs to the Christian religion, in such a way as may tend to the instruction of beginners.”

Therefore, there is no justification for treating the Summa as a study reserved for universities and seminaries.  We’d argue that this is one of the great failures of modern Catholic schools.
