Prayers for Unity of Faith

O Holy Spirit, Creator,
propitiously help the Catholic Church,
and by Thy supernal power
strengthen and confirm it
against the assaults of the enemy;
by Thy charity and grace
renew the spirit of Thy servants
whom Thou hast anointed,
that in Thee they may glorify
the Father and His only begotten Son,
Jesus Christ, our Lord.  Amen.

Holy Spirit, Spirit of Truth,
come into our hearts;
give to all peoples
the brightness of Thy Light,
that they may be well-pleasing
to Thee in unity of faith.
                                                      Amen
Pope Leo XIII
granted an indulgence of 300 days
for the recitation of the first prayer,
and 100 days for the second prayer.
