Thank you for asking! As you can see, the council clarified Catholic beliefs and practices.
Explanation:
The Council of Trent was a meeting of the Catholic Church that aimed to unify the Church behind one pope and incorporate Lutheran and Calvinist reforms. Source can be found here: https://en.wikipedia.org/wiki/Council_of_Trent
Why was the Council of Trent convened? The Council of Trent was the formal Roman Catholic reply to the doctrinal challenges of the Protestant Reformation. It served to define Catholic doctrine and made sweeping decrees on self-reform, helping to revitalize the Roman Catholic Church in the face of Protestant expansion.
Examples of self governance during the period of salutary neglect would be the implementation of town meetings and the general assembly known as the House of Burgesses.
