31. If the Eucharist is the centre and summit of the Church's life, it is likewise the centre and summit of priestly ministry. For this reason, with a heart filled with gratitude to our Lord Jesus Christ, I repeat that the Eucharist “is the principal and central raison d'être of the sacrament of priesthood, which effectively came into being at the moment of the institution of the Eucharist”.63
The centrality of the Eucharist in the life and ministry of priests is the basis of its centrality in the pastoral promotion of priestly vocations. It is in the Eucharist that prayer for vocations is most closely united to the prayer of Christ the Eternal High Priest. At the same time the diligence of priests in carrying out their Eucharistic ministry, together with the conscious, active and fruitful participation of the faithful in the Eucharist, provides young men with a powerful example and incentive for responding generously to God's call. Often it is the example of a priest's fervent pastoral charity which the Lord uses to sow and to bring to fruition in a young man's heart the seed of a priestly calling.
