Vocation, of course, does not refer exclusively to religious life or priesthood: these, however, are so unusual that frequently in Catholic circles they alone are called “vocations.”
The word vocation means “a calling”; it is extremely important to keep this in mind. We are called by the providential arrangement of circumstances, by the realities of life, by our own limitations and potential, by the historical moment, and by our own emotional, intellectual and psychological needs. If one follows the teachings of the Fathers and Doctors of the Church in this regard, one comes to accept that a vocation is found in the providential arrangement of significant aspects of life and also by the grace which we receive to make the best of these situations.
The loss of awareness of this providential aspect of vocation is one of the things that leads to an immense insecurity in modern life. When people forget the divine and providential element in their lives, they try desperately to find a course through life like a man on a raft with neither rudder nor map.
It has been a consistent belief of Christians that the Lord gives each of us something to do, some work to perform that makes us an essential link in the chain of life. Parents pass on life to their children and, by good examples, instruction, encouragement and membership in the Church contribute to their growth in the life of grace.
Single people, including priests and religious, pass on life in a psychological and spiritual way by being a help to those around them. This passing on of life and grace is the ultimate vocation of the Christian. Cardinal Newman sums it up well when he says: “I am a link in a chain, a bond of connection between persons. God has not created me for nothing. I shall do good; I shall do His work; I shall be an angel of peace, a preacher of truth, in my own place, while not intending it, if I do but keep His commandments.”
