R. And upon this Rock I will build My Church.
V/ LORD Jesus Christ, Who saidst unto Thine apostles; Peace I leave with you, My peace I give unto you; regard not our sins, but the faith of Thy Church, and grant unto her that peace and unity which are agreeable to Thy will. Who livest and reignest God forever and ever. R/ Amen.

They shall not partake of holy things, until a high priest shall arise for evidence and truth.  (Offertory for the Mass for the Election of a Pope)
