From a homily on the Gospels by Saint Gregory the Great, pope
The performance of our ministry

Let us listen to what the Lord says as he sends the preachers forth: The harvest is great but the laborers are few. Pray therefore the Lord of the harvest to send laborers into his harvest. We can speak only with a heavy heart of so few laborers for such a great harvest, for although there are many to hear the good news there are only a few to preach it. Look about you and see how full the world is of priests, yet in God’s harvest a laborer is rarely to be found; for although we have accepted the priestly office, we do not fulfill its demands.

Beloved brothers, consider what has been said: Pray the Lord of the harvest to send laborers into his harvest. Pray for us so that we may have the strength to work on your behalf, that our tongue may not grow weary of exhortation, and that after we have accepted the office of preaching, our silence may not condemn us before the just judge. For frequently the preacher’s tongue is bound fast on account of his own wickedness; while on the other hand it sometimes happens that because of the people’s sins, the word of preaching is withdrawn from those who preside over the assembly. With reference to the former situation, the psalmist says: But God asks the sinner: Why do you recite my commandments? And with reference to the latter, the Lord tells Ezekiel: I will make your tongue cleave to the roof of your mouth, so that you shall be dumb and unable to reprove them, for they are a rebellious house. He clearly means this: the word of preaching will be taken away from you because as long as this people irritates me by their deeds, they are unworthy to hear the exhortation of truth. It is not easy to know for whose sinfulness the preacher’s word is withheld, but it is indisputable that the shepherd’s silence while often injurious to himself will always harm his flock.

There is something else about the life of the shepherds, dearest brothers, which discourages me greatly. But lest what I claim should seem unjust to anyone, I will accuse myself of the very same thing, although I fall into it unwillingly—compelled by the urgency of these barbarous times. I speak of our absorption in external affairs; we accept the duties of office, but by our actions we show that we are attentive to other things. We abandon the ministry of preaching and, in my opinion, are called bishops to our detriment, for we retain the honorable office but fail to practice the virtues proper to it. Those who have been entrusted to us abandon God, and we are silent. They fall into sin, and we do not extend a hand of rebuke.

But how can we who neglect ourselves be able to correct someone else? We are wrapped up in worldly concerns, and the more we devote ourselves to external things, the more insensitive we become in spirit.

For this reason the Church rightfully says about her own feeble members: They made me a keeper of the vineyards, but my own vineyard I have not kept. We are set to guard the vineyards but do not guard our own, for we get involved in irrelevant pursuits and neglect the performance of our ministry.
