34 It will be for you, Venerable Brethren, placed by the Holy Spirit to rule the Church of God, to give the final practical decision in these cases, to which the Faithful will give their obedience and fidelity according to your instructions. And this is extremely close to Our heart, because the right intention and obedience are always and everywhere the indispensable conditions to draw down the Divine blessings upon the pastoral ministry and upon Catholic Action and to determine that unity of address and that fusion of energies which are an indispensable presupposition for the fruitfulness of the apostolate. With all Our spirit, therefore, We conjure the good Mexican Catholics to hold Obedience and Discipline dear. "Obey your prelates, and be subject to them. For they watch as being to render an account of your souls." And let this obedience be full of joy and a stimulus to greater energies: "That they may do this with joy, and not with grief" ( Hebrews xiii. 17). He who obeys unwillingly and only through force, venting his interior resentment in bitter criticism of his superiors and companions in work, of all that which is not according to his own way of viewing things, drives away the Divine benedictions, destroys the strength of discipline, and destroys where he ought to construct.
