The Immaculate Conception of the Blessed Virgin Mary - Solemnity
“You let her share beforehand in the salvation Christ would bring by his death and kept her sinless from the first moment of her conception.” (Opening prayer for the feast)
Father, all-powerful and ever-living God,
we do well always and everywhere to give you thanks.
You allowed no stain of Adam’s sin
to touch the Virgin Mary.
Full of grace, she was to be a worthy mother of your Son,
your sign of favor to the Church at its beginning,
and the promise of its perfection as the bride of Christ, radiant in beauty.
Purest of virgins, she was to bring forth your Son,
the innocent lamb who takes away our sins.
You chose her from all women to be our advocate with you
and our pattern of holiness.
In our joy we sing to your glory
with all the choirs of angels: Holy, holy, holy Lord, God of hosts!
