One of the world's most renowned masterpieces, the Summa Theologica, as the title indicates, is a summing up of all that can be known about God and humanity's relations with God. It is divided into three parts dealing with God, man, and the God-man respectively. It consists of 38 tracts, 631 questions, about 3000 articles, 10,000 objections and their answers. This brilliant synthesis of Christian thought has had a decisive and permanent impact on religion since the thirteenth century and has become substantially the official teaching of the Catholic Church. No library is complete without it. 5 volume set.
