"Woe to the priest who fails to respect his high dignity, and defiles by his infidelities the name of the holy God for whom he is bound to be holy. Corruptio optimi pessima. "Sublime is the dignity of the priest, but great is his fall, if he is guilty of sin; let us rejoice for the high honor, but let us fear for them lest they fall; great is the joy that they have scaled the heights, but it is insignificant compared with the sorrow of their fall from on high."
-- Pope St. Pius X, (Haerent Animo, To the Catholic Clergy on Priestly Sanctity)
Prayer for Priests (Ven. Mother Louise Margaret Claret)
O Jesus Eternal High Priest, divine Offerer of Sacrifice, Who, in an incomparable transport of love for men, Thy brethren, didst allow the Christian priesthood to issue from Thy Sacred Heart, deign to continue to pour out on Thy priests the life-giving streams of Infinite Love.
Live Thou in them, transform them into Thyself; render them by Thy grace the instruments of Thy mercies; act in them and through them, and grant, that, having been completely clothed with Thee by the faithful imitation of Thy adorable virtues, they may perform in Thy Name and by the strength of Thy Spirit, the works which Thou Thyself hast accomplished for the salvation of the world.
Divine Redeemer of souls,
see how great is the multitude of those who still sleep in the darkness of error; count the number of those unfaithful sheep that are walking on the edge of the eternal abyss; consider the crowds of the poor, the hungry, the ignorant and the weak, who are groaning in their state of abandonment.
Return to us by Thy priests, live again in very truth in them; act through them and pass again through the world teaching, pardoning, consoling, offering sacrifice, renewing the sacred bonds of love between the Heart of God and the hearts of men. Amen.
