This oath, which comes at the end of Ordination Mass following the post-communio prayer, is based on the LCC oath of 1916.
THE NEW PRIEST KNEELS BEFORE THE BISHOP
Bishop. Does thou promise to ourself and our successors due reverence and obedience in matters canonical?
New Priest(s). I do.
Bishop. Peace to you.
New Priest(s). And with thy spirit.
THE BISHOP CHARGES THEM THUS:
Bishop. Dearly beloved son(s) [daughter(s)], as what you have to handle is not without its mischances, I warn you that you do most diligently attend to the course of the Holy Eucharist and especially to that which regards the consecration, the breaking and communion of the Host. Be you also careful that in everything which appertains to the administration of the sacraments of Christ's holy church, you do adhere to the form set forth by lawful authority and presume not to depart therefrom in any detail.
THE BISHOP BLESSES THE NEW PRIEST(S)
Bishop. The blessing of God almighty, + the Father, + the Son and + the Holy Spirit, come down upon you, that you may be blessed in the priestly order and in the offering of sacrifice to almighty God, to whom belong honour and glory throughout the ages of ages.
THE BISHOP SITS AGAIN ON THE FALDSTOOL FACING THE NEW PRIEST(S), WHO CONTINUE TO KNEEL.
Bishop. Dearly beloved son(s) [daughter(s)], consider attentitevely the order you have taken and be ever mindful of the sacred trust reposed in you. Since it hat pleased our Lord to call you thus closer to Himself, forget not the service of your brethren, which is the golden pathway to his most glorious presence. Freely ye have received, freely give.
THE COMMUNIO VERSE IS SUNG AND THE HOLY EUCHARIST IS CONTINUED TO ITS CLOSE.
