Correct answer: Reaffirm the Catholic Church's teachings.
<em>Context/details:</em>
The Council of Trent, held over a span of years from 1545 to 1563, served to reform some abuses that were acknowledged by the Catholic Church. Mostly, though, the Council aimed to assert the full authority of Roman power and doctrine over the Protestant threat. The Protestants' teaching of <em>sola fide </em>("faith alone") was resoundingly rejected by the Council of Trent.
Reaffirming the Catholic Church's teachings became of focus of clergy education efforts initiated by the Council of Trent. Seminaries were established, and the Roman Catechism, also known as the Catechism of the Council of Trent, was commissioned by the Council and was published in 1566, with the intent of thoroughly educating the church's clergy.
