Prayer for one aspiring to the Priesthood

O My GOD, I am unworthy, most unworthy, to serve in the ministry of the priesthood, through which is offered on thy altars the Body and Blood of thy SON JESUS CHRIST. I am in no way worthy of this honour, being a miserable sinner, a mere nothing, even less than nothing by reason of my malice, fit for nothing but to commit sin. But while I feel within me an impulse drawing me to the ecclesiastical state, and of myself cannot tell whether it be presumption on my part or an inspiration from Thee, I humble myself before Thee, and I pray Thee to enlighten me to know if it be in accordance with thy good pleasure, for I would do nothing contrary to thy will. Do Thou, therefore, who art the Light of the world, shine forth in my heart, and if this thought is a call from Thee, give me the grace to obey it promptly, and worthily to correspond with it. But if, O LORD, Thou dost not call me to the priestly ministry, or Thou seest that as a member of it I should not be a good priest, but rather a disedification and a scandal to the Church, never permit me to enter a state which would be my damnation. Most holy Virgin, Mother of GOD, and Mother of good counsel, do thou support my poor prayer, and may I have the grace from our LORD by thy merits and intercession in all things to regulate my actions, not by my own, but by thy holy Will. PATER, Ave, Gloria.
