Listen to the Solemn Prayer to the Holy Trinity through St. Michael the Archangel. 

A prayer that the laity can pray is the following:

Prayer to Saint Michael the Archangel In the name of the Father, and of the Son, and of the Holy Spirit. Amen. Most glorious Prince of the Heavenly armies, Saint Michael the Archangel, defend us in our battle against principalities and powers, against the rulers of this world of darkness, against the spirit of wickedness in the high places.

Come to the assistance of men whom God has created to His likeness and whom He has redeemed at a great price from the tyranny of the devil.

The Holy Church venerates thee as her guardian and protector; to thee the Lord has entrusted the souls of the redeemed to be led into Heaven. Pray therefore the God of Peace to crush Satan beneath our feet, that he may no longer retain men captive and do injury to the Church.

Offer our prayers to the most High, that without delay they may draw His mercy down upon us. Take hold of the dragon, that old serpent, which is the devil and Satan, bind him, and cast him into the bottomless pit so that he should no more seduce the nations. Amen
