The authority to enact laws obligatory on all the faithful belongs to the Church by the very nature of her constitution. Entrusted with the original deposit of Christian revelation, she is the appointed public organ and interpreter of that revelation for all time. For the effective discharge of her high office, she must be empowered to give to her laws the gravest sanction. These laws when they bind universally, have for their object:
the definition or explanation of some doctrine, either by way of positive pronouncement or by the condemnation of opposing error;
the prescription of the time and manner in which a Divine law, more or less general and indeterminate, is to be observed, e.g. the precept obliging the faithful to receive the Holy Eucharist during the paschal season and to confess their sins annually;
the defining of the sense of the moral law in its application to difficult cases of conscience, e.g. many of the decisions of the Roman Congregations;
some matter of mere discipline serving to safeguard the observance of the higher law, e.g. the Commandments to contribute to the support of one’s pastors (Vacant, Dict. de theol. cath., s.v.).
