The last one – The Largely Catechized Life #117

“Therefore let every father of a family know that it is his duty, by the injunction and command of God, to teach these things to his children, or have them learn what they ought to know. For since they are baptized and received into the Christian Church, they should also enjoy this communion of the Sacrament, in order that they may serve us and be useful to us; for they must all indeed help us to believe, love, pray, and fight against the devil.Therefore let every father of a family know that it is his duty, by the injunction and command of God, to teach these things to his children, or have them learn what they ought to know.
