Priests and beloved sons, we hold in our hands a great treasure, a precious pearl, the inexhaustible riches of the blood of Jesus Christ; let us use them even to prodigality, so that, by the complete sacrifice of ourselves offered with Christ to the Eternal Father, we may become, in truth, mediators of justice, “in the things which appertain to God”,43Hebr., V, 1. and that we may deserve to have our prayers accepted and obtain a super-abundance of graces which may refresh and make more fruitful the Church and the souls of all men. Only when we have become one with Christ through His oblation and ours and when we have raised our voice with the choir of the inhabitants of the heavenly Jerusalem, as we read, “We join ourselves in song with them, our hopes in Holy Sion,”44Brev. Rom., Hymn. pro. off. Dedic. Eccl. only then, strengthened by the virtue of our Savior, shall we be able to descend in safety from the heights of sanctity to which we have attained, to bring to all men the life and the light of God by means of our priestly ministry.
