“It is a high crime indeed to withdraw allegiance from God in order to please men, an act of consummate wickedness to break the laws of Jesus Christ, in order to yield obedience to earthly rulers, or, under pretext of keeping the civil law, to ignore the rights of the Church; ‘we ought to obey God rather than men.’… No better citizen is there, whether in time of peace or war, than the Christian who is mindful of his duty; but such a one should be ready to suffer all things, even death itself, rather than abandon the cause of God or of the Church…

“Hallowed… in the minds of Christians is the very idea of public authority, in which they recognize some likeness and symbol as it were of the Divine Majesty, even when it is exercised by one unworthy… But, if the laws of the State are manifestly at variance with the divine law… then, truly, to resist becomes a positive duty…

“[W]hen necessity compels, not those only who are invested with power of rule are bound to safeguard the integrity of faith, but, as St. Thomas maintains: ‘Each one is under obligation to show forth his faith, either to instruct and encourage others of the faithful, or to repel the attacks of unbelievers.’ To recoil before an enemy, or to keep silence when from all sides such clamors are raised against truth… is base and is insulting to God, and… incompatible with the salvation of mankind…

“The chief elements of this duty consist in professing openly and unflinchingly the Catholic doctrine, and in propagating it to the utmost of our power…

“[P]rivate individuals… may take upon themselves… the task of communicating to others what they have themselves received, becoming, as it were, living echoes of their masters in the faith… Let each one… bear in mind that he both can and should, so far as may be, preach the Catholic faith by the authority of his example, and by open and constant profession of the obligations it imposes.” (Pope Leo XIII, Sapientiae Christianae, citations omitted)
