Ask the angels and saints to protect your marriage from all evil spirits that may want to destroy it.
Just one verse each day.
In many ways marriage is the “devil’s playground,” as he is intent on destroying humanity and he can be most effective if he attacks a couple. This is why prayer in a marriage is so important, as it can protect a couple from the assaults of evil spirits.
Here is an excerpt of a prayer from The Catholic Marriage Manual published in the 1950s that invokes the angels and saints, asking them for protection from the devil.
O Mary Mother of grace and of mercy! Protect our marriage against the wicked spirit, reconcile us with Thy Son, commend us to Him, that so we may be made worthy of His promises.
Saint Joseph, foster father of our Savior, guardian of His holy Mother, head of the holy Family! Be our intercessor, bless our marriage and defend our homes at all times.
Saint Michael, Guard us against all the wicked wiles of hell.
Saint Gabriel, Make us understand the holy will of God.
Saint Raphael, Preserve us from all sickness and all danger to our lives.
