Answer:
God
Step-by-step explanation:
The Summa Theologica was a compilation of detailed information pertaining to the worship of God, written by Thomas Aquinas. This compilation was composed of three distinct parts namely; Man, Christ and God. The first two parts and 90 questions of the third part were mainly the work of Thomas Aquinas.
His death limited the completion of this work, which was then augmented by the supplementary part- the commentaries made by Thomas Aquinas on Peter Lombard's sentences. The compilation was made between 1265 to 1273.
