Domine Iesu Christe, Pastor bone,
qui pro ovibus tuis animam dedisti,

ad pascua aeternae vitae perducamur in caelis….

who gave Your life for Your flock,
and while hanging on the Cross
commended us Your people and the flock of Your pasture
to the Virgin Mother:
as she is intervening, grant that we, following You our Shepherd here on earth,
may be led to the pastures of eternal life in the heavens.
