From Dom Guéranger's The Liturgical Year.

A HUMBLE lay-brother, Didacus of St. Nicholas, is welcomed to-day by his father St. Francis into the company of Bernardine of Siena and John Capistran, who preceded him by a few years to heaven. The two latter left Italy and the whole of Europe still echoing with their voices, the one making peace between cities in the name of the Lord Jesus, the other urging on the Christian hosts to battle with the victorious Crescent. The age which they contributed so powerfully to save from the results of the great schism and to restore to its Christian destinies, knew little of Didacus but his unbounded charity. It was the year of the great Jubilee, 1450. Rome having become once more, practically as well as theoretically, the holy city in the eyes of the nations, not even the most terrible scourges could keep her children at a distance. From every quarter of the globe, crowds, urged by the evils of the time, flocked to the sources of salvation; and Satan's work of ruin was retarded by seventy years.

Men doubtless attributed but a very small share of such results to the humble brother, who was spending himself in the Ara-Coeli, in the service of the plague-stricken; especially if they compared, him with his brethren, the great Franciscan apostles. And yet the Church pays to Didacus today the very same honours as we have seen her pay to Bernardine and John Capistran. What is this but asserting that before God heroin acts of hidden virtue are not inferior to the noble deeds that dazzle the world, if, proceeding from the same ardent love, they produce in the soul the same increase of divine charity.

The Pontificate of Nicholas V., which witnessed the imposing concourse of people to the tombs of the Apostles in 1450, was also, and still is, justly admired for the new impetus given to the culture of letters and the arts in Rome; for it belongs to the Church to adorn herself, for the honour of her Spouse, with all that men rightly deem great and beautiful. Nevertheless, who is there now of all the humanists, as the learned men of that age were called, who would not prefer the glory of the poor, unlettered Friar Minor, to that which vainly held out to them the hope of immortality? In the fifteenth century, as at all other times, God chose the foolish and the weak to confound the wise and the strong. The Gospel is always in the right.

Let us read the luminous life of this unlearned man, as given in the book of holy Church.

Didacus Hispanus, ex opido sancti Nicolai de Portu dioecesis Hisplanensis, ab ineunte aetate pii sub sacerdotis disciplina, sanctoris vitae solitaria in ecclesia, tyrocinium exercuit. Deinde ut firmius Deo se conjungeret, in conventu de Arizzafa fratrum Minorum (quos Observantes vocant) sancti Francisci regulam in status laicali professus est. manga ibi alacritate humilis obedientiae et regularis observantiae jugum subiens, contemplationi in primis deditus, mira Dei luce perfundebatur, adeo ut de rebus coelestibus, litterarum expers, mirandum in modum et plane divinitus loqueretur.

Canariis in insulis, ubi fratribus sui Ordinis praefuit, multa perpessus, martyrii aestuans desiderio, plures infideles verbo et exemplo ad Christi fidem convertit. Romam veniens anno jubilaei, Nicolao quinto Pontifice, aegrotorum curae in couventu Arae Coeli destinatus, eo caritatis affectu munus hoc exercuit, ut Urge annoniae inopia laborante, aegrotis tamen, quorum aliquando ulcera etiam lambendo abstergebat, nihil penitus necessarium defecerit. Eximia quoque fides et gratia curationum in so eluxit, cum lampadis, quae colucebat ante imaginem bestissimae Dei Genitricis, qum summa devotione colebat, oleo aegros inungens, signo crucis impresso, multorum morbos mirabiliter sanaverit.

Demum Compluti finem sibi, vitae adesse intelligens, lucera et obsoleta indutus tunica, conjectis in crucem oculis, singulari devotione illis verbis ex sacro hymno pronuntiatis: Dulce lignum, dulces, clavos, dulcia ferens pondea quae fuisti digna portare Regem coelorum et Dominum, animam Deo reddidit, pridie idus novembris, anno Domini supra millesimum quadringentesimo sexagesimo tertio. Ejus corpous cum menses non paucos (ut pio confluentium desiderio fieret satis_ insepultum mansisset, quasi jam incorruptionem induerit, odorem suavissimum efflavit. Illum multis et illustribus miraculis clarum Sixtus quintu Pontifix Maximus Sanctorum numero adscripsit.
Didacus[1] was a Spaniard, born at the little town of St. Nicholas de Porto in the diocese of Seville. From his early youth he began the practice of a perfect life, under the guidance of a pious priest in a solitary church. Then, in order to bind himself more closely to God, he made profession of the rule of St. Francis, in the convent of the Observantine Friars Minor at Arizzafa. There he bore the yoke of humble obedience and regular observance with great alacrity; and devoted himself especially to contemplation, in which he received wonderful lights from God, so that, illiterate as he was, he spoke of heavenly things in an ad­mirable manner, evidently by a divine gift.

He was sent to the Canary Isles to govern the brethren of his Order; and there he had much to suffer. He was burning with the desire of martyrdom; and by his words and example, he converted many infidels to the faith of Christ. Coming to Rome in the Jubilee year, in the pontificate of Nicholas V., he was entrusted with the care of the sick in the convent of Ara Cceli. With such loving charity did he acquit himself of this duty, that the sick wanted for nothing even during a famine in the city; he also sometimes cleansed their ulcers by suckir, them. He was remarkable for his great faith and his gift of healing; for by signing the cross upon the sick with oil from a lamp burning before an image of the Mother of God, to whom he had the greatest devotion, he miraculously cured many of them.

At length, when at Alcala, he understood that the end of his life was at hand. Clad in an old torn tunic, with his eyes fixed on the cross, he devoutly pronounced these words of the sacred hymn: O sweet wood, sweet are thy nails, and sweet thy burden; thou west worthy to bear the King and Lord of heaven He then gave up his soul to God, on the day before the Ides of November, in the year of our Lord 1463. His body was left unburied for several months, in order to satisfy the pious devotion of the numbers who came to see it; and, as though already clothed with immortality, it exhaled a sweet odour. He was renowned for many striking miracles, and was enrolled among the Saints by Pope Sixtus V.

“O Almighty, everlasting God, who by an admirable order dost choose the weak things of the world, that thou mayest confound whatever is strong; mercifully grant to our lowliness, that by the pious prayers of blessed Didacus, thy Confessor, we may be made worthy to be exalted to everlasting glory in heaven.”[2]

Such is the prayer addressed to God by the Church at all the liturgical Hours on this thy feast, O Didacus. Second her supplications; for thou art in high favour with him whom thou didst follow so lovingly along the way of humility and voluntary poverty. A royal road indeed, since it brought thee to a throne which far outshines all earthly thrones. Even here below, thou dost far surpass in renown many of thy contemporaries, who are now as forgotten as they were once illustrious. Sanctity alone merits crowns that endure through all ages of time and for all eternity; for God is the final awarder, as he is the supreme reason, of all glory, just as in him lies the principle of all true happiness both for this world and for the next. May we all, after thine example and by thine assistance, learn this by our own blessed experience!
