34 Here is the source of the harmony and equilibrium which prevails among the members of the Mystical Body of Jesus Christ. When the Church teaches us our Catholic faith and exhorts us to obey the commandments of Christ, she is paving a way for her priestly, sanctifying action in its highest sense; she disposes us likewise for more serious meditation on the life of the divine Redeemer and guides us to profounder knowledge of the mysteries of faith where we may draw the supernatural sustenance, strength and vitality that enable us to progress safely, through Christ, towards a more perfect life. Not only through her ministers but with the help of the faithful individually, who have imbibed in this fashion the spirit of Christ, the Church endeavors to permeate with this same spirit the life and labors of men - their private and family life, their social, even economic and political life - that all who are called God's children may reach more readily the end He has proposed for them.
