Temperance is love surrendering itself wholly to Him who is its object; courage is love bearing all things gladly for the sake of Him who is its object; justice is love serving only Him who is its object, and therefore rightly ruling; prudence is love making wise distinction between what hinders and what helps itself.
Saint AugustineAs to those other things which we hold on the authority, not of Scripture, but of tradition, and which are observed throughout the whole world, it may be understood that they are held as approved and instituted either by the apostles themselves, or by plenary Councils, whose authority in the Church is most useful, e.g. the annual commemoration, by special solemnities, of the Lord's passion, resurrection, and ascension, and of the descent of the Holy Spirit from heaven, and whatever else is in like manner observed by the whole Church wherever it has been established.
