Echoing the thought and writing of St. Paul, Marmion stresses that the priestly life must be dominated by Christ and in constant dependence on His merits, His grace and His activity in the soul of the priest. In all his actions, in the sacred acts of worship, the administration of the sacraments, private prayer and devotions, and serving the various needs of his flock, Marmion says the priest must always see himself as the minister of the Savior, as Alter Christus.
