Sacramentals are powerful and can be a means to express your faith in God and a means that God uses to draw us closer to Him and to work through our lives and protect us. Besides the ones given to us by our Blessed Mother - Miraculous medal, Brown scapular- many saints have voiced their thoughts on the strength of Sacramentals. Such as St. Teresa: “From long experience I have learned that there is nothing like holy water to put devils to flight and prevent them from coming back again. They also flee from the Cross, but return; so holy water must have great virtue."
The same can be said about most Sacramentals, once blessed they have the power to bring down God's graces upon the user, they protect one from diabolical attacks of Satan and the evil spirits, they have the power to bring a soul to conversion and lead them to the Sacraments, they can bring spiritual and physical healing to a soul, they can remove venial sins, give you the grace to fight temptations and much more.
Sacramentals do not confer the grace of the Holy Spirit in the way that the Sacraments do, but by the Church's prayer, they prepare us to receive grace and dispose us to cooperate with it. "For well-disposed members of the faithful, the liturgy of the Sacraments and Sacramentals sanctifies almost every event of their lives with the divine grace which flows from the Paschal mystery of the Passion, Death, and Resurrection of Christ. From this source all Sacraments and Sacramentals draw their power. There is scarcely any proper use of material things which cannot be thus directed toward the sanctification of men and the praise of God.''
We must continue to have recourse to the abundant graces granted through such powerful sacramentals as the Holy Rosary, the Scapular of Our Lady of Mt. Carmel, the Miraculous Medal, and so many others that have found favor with God. In these dawning years of the 21st century, in days of increasing compromise and capitulation that come from embracing the world, we must protect our authentic Catholic patrimony. A significant and invaluable part of that patrimony is found in Catholic sacramentals.
So use them to sanctify your lives,those of your family and friends,your loved ones and help lead souls to the kingdom of heaven.
