The Summa Theologiae of Thomas Aquinas is one of the greatest and most influential Christian theological works ever written, and is the first Systematic Theology after the Sentences of Peter Lombard. It was composed in stages between 1268 and 1273, drawing upon previous writings and lectures, and remained unfinished at Thomas' death in 1274. The work was completed by Thomas' friend Reginald of Piperno, based on the master's commentary on the Sentences. It is divided into 3 parts, broadly:
Theology - God, His nature and Person, the Trinity, Creation, etc.
Man, Christian doctrine and practice, the religious life, etc.
The work of Christ, the Sacraments, and Last Things
The entire work is designed according to the Quaestiones Distputatae (Disputed Questions) model: question, answers for and against from authorities (both Christian and secular), followed by Thomas' own response and a refutation of the authorities which are (or appear to be) "for" the untenable.
