27 The priest dedicates himself to the service of the Lord Jesus and of His Mystical Body with complete liberty, which is made easier by his total offering, and thus he depicts more fully the unity and harmony of the priestly life. (47) His ability for listening to the word of God and for prayer increases. Indeed, the word of God, as preserved by the Church, stirs up vibrant and profound echoes in the priest who daily meditates on it, lives it and preaches it to the faithful.
