Pope Leo XIII teaches that the Church's raison d'être is to guard and propagate – in all its integrity and purity – both Christian doctrine and the fitting and devout worship of God. In faithfully doing this, the Church continues the mission of Our Savior and King, Jesus Christ. It is by true doctrine (lex orandi) and right worship (lex credendi) that the Church helps save men's souls. To further this end Christ established a hierarchy. A grave crisis exists today because so many in the hierarchy are not carrying out this mission. Every Catholic has the responsibility –within the scope of his duty– to guard, protect and live according to true doctrine and right worship. Learn your faith and put it into practice!
