1 Peter 2:5

You also, as living stones, are being built up as a spiritual house for a holy priesthood, to offer up spiritual sacrifices acceptable to God through Jesus Christ.

Revelation 1:6

And He has made us to be a kingdom, priests to His God and Father; to Him be the glory and the dominion forever and ever. Amen.

Hebrews 7:12

For when the priesthood is changed, of necessity there takes place a change of law also.
