Consecration to the Immaculate Heart of Mary

Virgin of Fatima, Mother of Mercy,
Queen of Heaven and Earth, Refuge of sinners,
we who belong to the Marian Movement of Priests,
called to form the cohort of your priests,
today consecrate ourselves in a very special way
to your Immaculate Heart.
with you and through you,
all the obligations assumed by our baptismal
and priestly consecration.

We further pledge to bring about in ourselves
that interior conversion that will free us
of all human attachment to ourselves, our career,
our comforts, or to easy compromises
with the world so that, like you,
we may be available only to do always the Will of the Lord.

And as we resolve to entrust to you,
O Mother most sweet and merciful,
our priesthood, so that you may dispose of it
for all your designs of salvation
in this hour of decision that weighs upon the world,
we pledge to live it according to your desires,
especially as it pertains
to a renewed spirit of prayer and penance,
the fervent celebration of the Holy Eucharist
and of the Liturgy of the Hours,
the daily recitation of the holy rosary,
the offering of Holy Mass in your honor
on the first Saturday of every month,
and a religious and austere manner of life,
that shall be a good example to all.

We further promise you the greatest loyalty to the Gospel,
of which we shall always be genuine and courageous heralds,
even, if necessary, to the shedding of our blood.
We promise loyalty to the Church,
for whose service we have been consecrated.

Above all, we wish to be united
with the Holy Father and the hierarchy,
firmly adhering to all their directives,
so as thus to set up a barrier to the growing confrontation
directed against the Magisterium,
that threatens the very foundation of the Church.

Under your maternal protection,
we want moreover to be apostles of this sorely needed unity
of prayer and love for the Pope,
on whom we invoke your special protection.

And lastly, we promise to lead the faithful
entrusted to our care to a renewed devotion to you.

Mindful that atheism has caused shipwreck in the faith
to a great number of the faithful,
that desecration has entered into the holy temple of God,
not sparing even many of our brother-priests,
and that evil and sin are spreading
more and more throughout the world,
we make so bold as to lift our eyes trustingly to you,
O Mother of Jesus and our merciful and powerful Mother,
and we invoke again today
and await from you the salvation of all your children,
O clement, O loving, O sweet Virgin Mary.
