66 It is desirable to have the faithful in large numbers take an active part in the sacrifice of the Mass each and every day and receive the nourishment of Holy Communion with a pure and holy mind and offer fitting thanks to Christ the Lord for such a great gift. They should remember these words: "The desire of Jesus Christ and of the Church to see all the faithful approach the sacred banquet each and every day is based on a wish to have them all united to God through the Sacrament and to have them draw from it the strength to master their passions, to wash away the lesser sins that are committed every day and to prevent the serious sins to which human frailty is subject." (67) And they should not forget about paying a visit during the day to the Most Blessed Sacrament in the very special place of honor where it is reserved in churches in keeping with the liturgical laws, since this is a proof of gratitude and a pledge of love and a display of the adoration that is owed to Christ the Lord who is present there.
