"A priestly soul is a soul possessed by the Holy Spirit and anointed by Him to unite her intimately to Jesus through love and suffering in order to offer and immolate Him for the glory of God and the good of souls." (Servant of God, Archbishop Luis M. Martinez)
"...the People of God shares in the royal office of Christ...What is as royal for a soul as to govern the body in obedience to God? And what is as priestly as to dedicate a pure conscience to the Lord and to offer the spotless offerings of devotion on the altar of the heart? (CCC)
"But you are a chosen race, a royal priesthood, a holy nation, God's own people..." (1Peter 1:9)
