Our Lord told St. Gertrude the Great that this prayer would release 1000 souls from purgatory each time it is said.
The prayer was later extended to include living sinners as well.
I offer You the Precious Blood of Your Divine Son,
Our Lord Jesus Christ
in conjunction with all Holy Masses
today celebrated all over the world,
for suffering souls in Purgatory, for dying,
for sinners in the world,
for sinners in the universal Church,
for sinners in my family
and also in my house. Amen.
The Approval and Recommendation does NOT include this extension. Approval and Recommendation (sqd.) M. Cardina Pahiarca at Lisbon, Portugal, on March 4, 1936
