December is the Month of the Immaculate Conception
Prayer to Mary
O God,
who by the Immaculate Conception of the Virgin
didst make ready a fitting habitation for Thy Son,
we beseech Thee
that Thou who didst keep her clean from all stain
by the precious death of the same Son,
foreseen by Thee,
may grant unto us in like manner
to be made clean through her intercession
and so attain unto Thee.
Through the same Christ our Lord.
Amen
