Nice thought, except it is false.
Prayer,
Penance (forgiving mercy), and...
Almsgiving....
Those are the most powerful weapons. The Cross and the Gospel of Jesus Christ. The Catholic Faith.
"Education" gave the world the Protestant Revolution, the First World War, the Second World War, "no-fault" divorce, contraception, abortion, euthanasia, selling baby parts, and now, total gender confusion.
No, the most important weapon is divine mercy! the cross, Jesus Christ's cross!
