It is impossible to exaggerate the close relation between the Holy Eucharist and vocations to the priesthood and religious life.
This is only to be expected once we realize that every vocation is a special grace from God, and the greatest source of grace we have is the Eucharist as Presence, Sacrifice, and Communion.
Faith tells us that Christ is really present on our altars, that He really offers Himself in the Mass, and that we really receive Him in Holy Communion. In each case, the Living Christ is now inspiring men and women to give themselves to Him with all their hearts and follow Him in the extension of His Kingdom.
The Eucharist, therefore, is the best way to foster vocations. This means that persons who attend Mass, receive Communion and invoke Christ in the Blessed Sacrament obtain light and strength that no one else has a claim to.
The Eucharist is finally the infallible way of preserving one’s vocation. This is especially true of devotion to the Real Presence. Is it any wonder that saintly priests and religious over the centuries have been uncommonly devoted to the Blessed Sacrament? They know where to obtain the help they need to remain faithful to their vocations. It is from the same Christ Who called them and Who continues to sustain them in His consecrated service.
Vocations begin with the Eucharist; they are developed through the Eucharist; and they are preserved by the Eucharist. All of this is true because the Eucharist is Jesus Christ, still on earth, working through men and women whom He calls to share His Plan for salvation.
