Like Jesus in His public life, he was, says St. Cyprian, "the Pastor who guards the flock, the Pilot who steers the ship, the King who leads his people, and in one word the Bishop of the Church".
Sacerdotes Dei, benedicite Dominum: sancti et humiles corde, laudate Deum. * Benedicite, omnia opera Domini, Domino: laudate et superexaltate eum in saecula.
O ye priests of the Lord, bless the Lord: O ye holy and humble of heart, praise God. * All ye works of the Lord, bless the Lord: praise and exalt Him above all for ever.
Gregem tuum, Pastor aetérne, placátus inténde: et, per beátum Lúcium Mártyrem tuum atque Summum Pontíficem, perpétua protectióne custódi; quem totíus Ecclésiae praestitísti esse pastórem.
O God, who givest us joy by the annual solemnity of blessed L:ucius Thy martyr and bishop, mercifully grant that we may rejoice in his protection whose birthday we celebrate.
