you have made all those who are born again in Christ
to be your chosen people, royal priesthood and holy nation.
Grant us both the will and the power to do what you command,
that your people who are called to eternal life
may have the same faith in their hearts
and the same devotion in their actions;
through Jesus Christ our Lord.

“chosen people,”etc., This prayer quotes 1 Peter 2:9. In this version, the reference was expanded. In the original, the line is “…to be a royal and priestly race.”
