Prior to the blessing, the priest vests himself surplice and white stole.
Priest: Our help is in the name of the Lord.
People: Who made heaven and earth.
Priest: The Lord be with you.
People: And also with you.
Let us pray.
Almighty and merciful God,
Who by the many appearances on earth
of the Immaculate Virgin Mary
were pleased to work miracles again and again
for the salvation of souls;
kindly pour out Your blessing + on this medal,
so that all who devoutly wear it
and reverence it
may experience the patronage
of Mary Immaculate
and obtain mercy from You;
through Christ our Lord.
Amen.
The priest sprinkles the Miraculous Medal(s) with Holy Water and then presents it to person(s) saying:
Take this holy medal;
wear it with faith,
and handle it with due devotion,
so that the holy
and Immaculate Queen of Heaven
may protect and defend you.
And as she is ever ready
to renew her wondrous acts of kindness,
may she obtain for you in her mercy
whatever you humbly ask of God,
so that both in life and in death
you may rest happily in her motherly embrace.
Amen.
Lord, have mercy.
Christ, have mercy.
Lord, have mercy.
Our Father…
Priest: And lead us not into temptation.
People: But deliver us from evil.
Priest: Queen conceived without Original Sin.
People: Pray for us who have recourse to thee.
Priest: O, Lord, hear my prayer.
People: And let my cry come unto thee.
Priest: The Lord be with you.
People: And also with you.
Let us pray.
Lord Jesus Christ,
Who willed that Your Mother,
the Blessed Virgin Mary conceived without sin,
should become illustrious
through countless miracles;
grant that we who ever seek her patronage
may finally possess everlasting joys.
We ask this of You,
Who lives and reigns forever and ever.
Amen.
