Variation #1:Start with the 4 Our Fathers (1 each for St. Michael, St. Gabriel, St. Raphael and our Guardian Angel). There is a 2nd medal - the Guardian Angel medal, then as above.
Prayer on the Guardian Angel medal:
St. Michael, the Archangel, defend us in battle, be our protection against the malice and snares of the devil. We humbly beseech God to command him, and do thou, O Prince of the heavenly host, by the divine power thrust into hell Satan and the other evil spirits who roam through the world seeking the ruin of souls. Amen
Variation #2 (Also known as the Chaplet of the Holy Angels):On the medal:
O my Jesus, I offer you this chaplet to Your Divine Heart, that You may render it perfect, thus giving joy to Your holy Angles and so they may keep me under their holy protection, above all at the hour of my death to which I invite them with all my heart. Strengthened by their presence, I will await death with joy and be preserved from the assaults of hell.
I beseech you also, dear Angels, to visit immediately the souls in Purgatory, especially my parents, my friends, my benefactors; help them so that they will soon be delivered. Do not forget me either after my death. This I beg you with all my heart, through the Sacred Heart of Jesus and the Immaculate Heart of Mary. Amen.
On the 1st bead:
St. Michael, I recommend the hour of my death to you. Hold the Evil One prisoner, so that he may not battle against me and do harm to my soul.
On the 2nd bead:
St. Gabriel, obtain for me from God lively faith, strong hope, ardent charity and great devotion to the Blessed Sacrament of the Altar.
