In the lives of the Saints we find other innumerable proofs of the power of the Sign of the Cross.
St. Dominic raised the dead to life by the holy Sign.
St. Vincent Ferrer worked hundreds hundreds of miracles by this blessed Sign.
Tertullian relates that the Christians in the first centuries began everything with the Sign of the Cross.
When they left their homes or reentered them, they blessed themselves.
Arising in the morning or going to rest at night, they made the Sign of the Cross with great devotion.
In all dangers and temptations they made the same holy Sign.
St. Patrick made the Sign of the Cross 400 times a day.
All good Christians should strive to make the Sign of the Cross as frequently as possible.
By this blessed Sign, devoutly made, we give immense glory to God, for we offer to Him the infinite merits of the death of Jesus Christ.
But never, never should a Christian make the Sign of the Cross hastily or irreverently.
