The Divine Liturgy is the most powerful means of pastoral service

The priestly service includes many responsibilities. The priest must satisfy all the requirements of his rank. They include the duties of teaching, spiritual guidance, missionary work, and divine service, taking care of the sick, prisoners, sorrowful, and many other things....

However, God can give or not give certain talents to a priest as to anyone. A priest may prove to be a poor speaker or incapable administrator of his parish, a dull instructor of the Holy Scripture. He can be an insensitive or even too demanding a confessor. He can be at a loss socially. But this will be forgiven him and will not blot out the worth of his spiritual work, if only he possesses a feeling for the Eucharist, if his main occupation is the stewardship of the Mysteries and service at the Divine Liturgy for the mystical union of himself and his flock to the body of Christ, for the sake of being partakers of the divine nature in the words of the Apostle Peter (2 Peter 1:4). A priest is given no greater authority or mystical means than this service to the Mystery of the Body and Blood of Christ. This must be the life's work of the priest.... Nowhere and by no method are prayer and spiritual expoit so realized in a priest as in the sacrament of the Eucharistic sacrifice....

The most spiritually compelling priests always took great joy in their celebration of the eucharistic service and its prayers...

Summing up what has been said about the pastoral gift, we must draw the following conclusion. A special gift is given to the pastor in the laying on of hands... the joyous responsibility of renewing and enlivening souls for the Kingdom of God. This renewal can be accomplished in part through a moral influence upon the personality of those guided, through compassionate love for the guilty, through a sympathetic encounter with their personalities, but, mainly, through the Eucharistic service and joining the faithful, through it, to the mysterious Body of the Church. Anyone beside a priest can influence a neighbour. A mother and educator can commiserate. A close friend can share one's sorrows. But the leading of the celebration of the Eucharist is the responsibility of the priest. The Divine Liturgy is the most powerful means of pastoral service... A priest must always remember that he is called to bring God's mysteries into the heart of the community... [this] is the most powerful means of pastoral influence through which to breing about the moral and mystical revival of the faithful and the parish.
