“The Sacraments are outward signs instituted by Christ to give grace. Signs, there are all kinds of signs around us but sacraments are unique as signs because they are signs of the presence and love of God for us and of our desire to come in contact or encounter God. Sacraments are living signs. They are dynamic signs. They involve the action of the church. Sacraments are of the church and for the church. They are truly the action of God. …”
