Summa theologica was used to teach catholic priests.

Thomas Aquinas' Summa Theologica was used to teach Catholic priests.

Explanation:

The Theological Summa was written by St. Thomas Aquinas. Since the word "Aquinas" ends with the letter "s", we must place the apostle after these "s" to indicate that the Theological Supreme belongs to St. Thomas Aquinas. For this reason, the sentence is spelled correctly as "Thomas Aquinas' Summa Theologica was used to teach Catholic priests."

The Theological Summa was a set of doctrines that constituted one of the foundations of the dogmatics of Catholicism and considered one of the main philosophical works of scholasticism. In addition, it was used to teach Catholic priests.
