'The seventh weapon with which we can conquer our
enemies is the memory of Holy Scripture which we must carry in our
hearts and from which, as from a most devoted mother, we must take
counsel in the things we have to do. Thus we read of the most prudent
and consecrated virgin St. Cecilia where it says: "She always bore the
gospel of Christ hidden in her heart." And with this weapon, our savior
Christ Jesus conquered and confounded the devil in the desert saying:
"It is written" (Lk 4.1-13). Therefore, dearest sisters, let not the
daily readings that you read in the choir and at table go without
effect; and let the thoughts which you hear each day in the gospels and
epistles at Mass be new letters sent to you by your heavenly spouse.'
