Pope Gregory’s Life

Becoming a Monk

Early in life he entered a political career, becoming praefectus urbi, then, after some hesitation, he decided to devote himself fully to God, around 574–575, probably after the death of his father. Then, able to dispose of inherited patrimony, he founded six monasteries in Sicily, in the territories inherited from his mother, and another one, named after St. Andrew, in the family palace on the Caelian, where he retired.

Here he led an ascetic life, guided by self-discipline, humility and Scriptural meditation, which are recurring themes in his writings. Many of his future collaborators entered this monastery, including Maximian, who became bishop of Syracuse, and Augustine, who was later sent on a mission to Britain. The rule of life adopted here was not necessarily that of St. Benedict, as is often thought because of the author’s interest in the saint.

Becoming a Deacon

He lost monastic peace when Pelagius II ordained him deacon and sent him to Constantinople as apocrisarius to the emperor, Tiberius II at first, then from 582 Maurice. He was sent in order to solicit aid against the Longobards in Italy, who had arrived on the peninsula some ten years prior, and continued their incursions into the territories of the Byzantine Empire, including Rome.

In these years (ca. 579–586) to his diplomatic efforts was added the doctrinal controversy with Eutyches of Constantinople on resurrection of the body; this ended with the imperial approval of the theory supported by Gregory.

Meanwhile, he became deeply involved in the interpretation of the book of Job, at the request of his friends. Among them was Leander of Seville. Gregory remained in contact with him after his return to Rome.

Becoming the Pope

There, Pelagius made use of Gregory in the political and ecclesiastical problems concerning, among other things, the Lombards and the question of the Three Chapters (see the letter written to the bishops of Istria by Gregory on behalf of Pelagius).

The pontiff died 7 February 590, struck by bubonic plague following the flood of the Tiber in 589; a week later, Gregory organized a procession in the city, bound for S. Maria Maggiore, to implore from God the end of the plague.

Already esteemed for his role under Pelagius, he was acclaimed by the Roman people as Pelagius’s successor and, after a few months, received imperial approval, followed by the episcopal consecration on 3 September 590.

Gregory the Great’s Writings

Among the writings attributed to Gregory, those largely considered authentic belong basically to three genres: letters, exegesis, hagiography. In their various stages of composition they cover between the eighties of the 6th c. and the pontiff’s death.

Moralia in Iob

The first are the Moralia in Iob, begun during his stay in Constantinople, completed in Rome before his election as bishop, with later occasional editing approximately up to the year 600. In the thirty-five books a complete interpretation unfolds, verse by verse, of the book of Job, considered from four points of view: literal, allegorical, typological and moral.

Similar criteria, which in general also apply to his other commentaries, are presented in the dedicatory letter to Leander of Seville, one of the addressees of this exegetical work, considered by Gregory providential.

In fact, by a divine plan, the sorrow of Job finds in him an interpreter that is much more capable of understanding him, as he is similarly subject to suffering. He sees in Job not only the “type” of Christ, with his redemptive passion, but also that of the church, whose history is understood as the history of preaching the gospel and of the subsequent trials, until the end of time, when, once the elect are gathered together from all nations, it will enjoy the eternal reward promised by the Lord.

Read Gregory the Great’s Thoughts on Job

The Ancient Christian Commentary on Scripture contains excerpts of the Church father’s writings for nearly every passage of the Bible. Below you’ll find Gregory’s thoughts on Job 9:27-28. Originally, this excerpt is from his work entitled Morals on the Book of Job.


If I say, ‘I will forget my complaint,
I will change my expression, and smile,’
I still dread all my sufferings,
for I know you will not hold me innocent.

Recognition of Human Limitation, Gregory the Great

For we say that “we never ought to speak this way” when we transgress the limits of our frail nature by excessive questioning. We reproach ourselves in dread and remind ourselves of heavenly awe, in which our mind’s face is altered. The mind, in the first instance, failing to comprehend its limits, is boldly investigating things above. Afterwards, discovering its own infirmity, it begins to entertain awe for what it is ignorant of.

However, in this very change there is pain, for the mind is very greatly afflicted that, in payment for the first sin, it is blinded to the understanding of things touching it.… Therefore, because our very good actions themselves cannot escape the sword of ambushed sin unless they are guarded every day by anxious fear, it is rightly said by the holy man in this place, “I was afraid of all my works.”

It is as if he said with humble confession, “What I have done publicly, I know, but what I may have been secretly subject to through this I cannot tell.”

For often our good points are spoiled by deceit robbing us, in that the earthly desires unite themselves to our righteous actions. Oftentimes they come to nothing from sloth intervening, in that, when love grows cold, they are starved of the fervor in which they began. Therefore, because the stealth of sin has scarcely got the better of those even in the very act of virtue, what safeguard remains for our security? Even in our virtue, we always tread with fear and caution.

What he adds after this presents itself as a very great difficulty to the mind: “I know that you would not spare one that offends.” For if there be no “sparing of one that offends,” who can be rescued from eternal death, seeing that there is no one to be found clear of sin?

Or does this mean, alternatively, that God does spare one who repents but not one that offends (on the premise that when we bewail our offenses, we are no longer offending)?
