"Not trying to know." Thus children who idle their time at Sunday school or religious instruction, and do not learn their Catechism, sin against faith in the first way. In like manner grown persons who do not sometime or other endeavor to hear sermons or instructions, to attend missions or learn from good books, sin against faith. "Refusing to believe," as all those do who leave the true religion, or who, knowing it, do not embrace it. "Neglecting to profess." We may do this by not living up to the practice of our holy religion. We believe, for example, we should hear Mass every Sunday and holy day; we should receive the Sacraments at certain times in the year; but if we only believe these things and do not do them, we neglect to profess our faith, neglect to show others that we really believe all the Church teaches, and are anxious to practice it. Many know and believe what they should do, but never practice it. Such persons do great injury to the Church, for persons who do not live up to their holy religion but act contrary to its teaching give scandal to their neighbor. How many persons at present not Catholics would be induced to enter the true Church if they saw all Catholics virtuous, truthful, sober, honest, upright, and industrious! But when they see Catholics--be they ever so few--cursing, quarrelling, backbiting, drinking, lying, stealing, cheating, etc.--in a word, indulging in the same vices as those who claim to have no religion, what must they think of the moral influence of Catholic faith? Thus they do great injustice to the Church and the cause of religion, and are working against our Blessed Lord when they should be working for Him.
