The Catholic Church has always acknowledged the predominant place and significance of the Ten Commandments in the life if each of its members. We need from time to time, however, to be reminded of this fact in order that we might truly glorify the Lord not only with our lips but also in our actions. This little booklet provides just such a reminder. It is based on the Catechism on the Catholic Church of 1992 and its subsequent Compendium of 2005 and is a positive approach toward Catholic morality, lifestyle and attitude. It provides several brief but thoughtful meditations on how we can live our wonderful vocation as Catholics by responding “Yes” to the Lord’s invitation to become saints, holy and happy brothers and sisters of the Lord.
