He who made everything and who governs by a prudent arrangement wanted order to flourish in His Church. He wanted some people to be in charge and govern and others to be subject and obey. Therefore, the Church has, by its divine institution, the power of the magisterium to teach and define matters of faith and morals and to interpret the Holy Scriptures without danger of error. It also has the power of governance to preserve and strengthen in the true doctrine those whom it welcomes as children and to make laws concerning all things which pertain to the salvation of souls, the exercise of the sacred ministry, and divine worship. Whoever opposes these laws makes himself guilty of a very serious crime.
--Pope Gregory XVI,
Commissum Divinitus, 1835
