Ave Maria!
How can a person tell the difference between a calling and simple ambition?
I think the ambition helps you to move forward and motivates you to discern the call. Hopefully a priest will have the ambition to become a holy priest, a saint, every day of his life. The flame must be stoked continuously until the end, else lukewarmness creeps in.
In these days even the slightest inspiration is a great gift from God, so don’t take it for granted. Trust God and run with it. “Do not be afraid”!. If you hesitate, the world will snatch this gift from you. If God is not calling you to religious life, He will reveal this to you in due time and order things properly. If called to marriage, a devout Catholic wife He will be preparing for you, but only if you trust and have patience.
St. Alphonsus writes,
The divine call to a more perfect life is undoubtedly a special grace, and a very great one, which God does not give to all; hence he has much reason to be indignant against those who despise it. How greatly would not a prince think himself offended if he should call one of his vassals to serve him near his person, and this vassal should refuse to obey the call!
I’m not sure how I could know if it’s an actual calling, so to speak, or simple blind ambition to fulfill a little dream.
If it were the latter, would that not be considered an immoral reason to enter the priesthood, to become a priest with the express intention of being assigned to a certain part of the priesthood?
Ambition to higher positions, even in the Church, are not humble inspirations and should be avoided. However, for example, in humility you could acknowledge a special talent God has given for preaching, and aspire to enter a community that focuses on preaching, but not to be on the council or to be the superior!
Many saints initially had all sorts of inspirations, including ones that weren’t the holiest, but God uses them all to call us, and eventually they become purified. Whether it’s a child wanting to be Pope, or a girl who likes the pretty habit, God can use them. St. Pio wanted to be a Capuchin Franciscan because he liked the pointy hood when he was young, but as he matured he learned the joy of the Order of Penance, and the rest of course is history.
Frequent the Sacraments. Read the lives of the saints (maybe those known for their priestly sanctity, like St. John Vianney).
Consecrate yourself to Our Lady, and put your vocation in Her most loving hands. She, who raised our great High Priest, can certainly form you into Him, to become “alter Christus” (another Christ).
Mary, Mother of Vocations, pray for us! St. John Vianney, pray for us! Ave Maria!
In the Sacred Hearts of Jesus and Mary,
Friar John Paul
P.S. I’ll be the 4th person to advise a spiritual director, in order to emphasis how critical it is to not only discern your vocation, but to grow in holiness, both of which every Catholic should do.
