His order continued to expand, many religious flocked to him, and gifts of manors and farms pouring in from all quarters, many monasteries arose under his rule.
The charge of his Order now became so onerous that he is said to have attended the general chapter of the order at Citeaux, in the year 1140, for the purpose of formally resigning his authority. To this, however, his brother abbots refused their consent, and Gilbert returned to his labours, which he was to relinquish only with his life.
A peculiar interest attaches to this chapter, from the circumstance related by the same writer,[19] who tells us of Gilbert's presence there, that the Pope Eugenius[20] was present and took part in the proceedings, "not, however, presiding as with apostolical authority, but in brotherly love taking his seat among the assembled abbots, as one of themselves."
Returned to Sempringham, Gilbert resumed his life of prayer and mortification, observing the fasts of the Church with such rigidity that from Septuagesima to Easter, and throughout Advent, he not only abstained from flesh-meat, but even a morsel of fish never passed his lips. He practised also great austerity with regard to sleep, hardly allowing himself to lie down for months together.
His unwearied devotion and severe asceticism so forwarded his growth in grace that his influence over the religious under his authority became almost unbounded; with such prudence and persuasiveness was he endued, that he allayed without difficulty a serious disturbance which arose in the order from a spirit of insubordination that had crept in among the lay brethren. Overcome by his skilful reasonings and loving exhortations, the greater number returned to their obedience, "whereas," the chronicler adds, "those who held out and refused to do so, all perished miserably." His holiness and his acceptance with God were also attested by many miracles and wonders. Being at one time afflicted with a very severe fever, a friend came to condole with him; the saint enquired whether he had ever experienced the sensations of a fever; finding that he had not, Gilbert asked him whether he would be willing to take the fever from which he himself was suffering, if he might be thereby cured. The friend assented, and returning home, was the next morning seized with the fever, whereas the saint arose entirely free from it. Another time, a man suffering from gout was cured by simply wearing Gilbert's list slippers; and another man, sick of a fever, was healed by drinking out of his cup.
Overcome at length by the infirmities of advancing age, he resigned the charge of Sempringham to one of his disciples, Roger by name; but he seems still to have retained his authority, as it is mentioned that some time after this, he gave shelter to S. Thomas à Becket in one of his houses when that prelate, worsted in his contest with Henry II., was wandering about the kingdom in search of means to escape to the continent. He also supplied the archbishop with money during his exile, thereby drawing upon himself the displeasure of Henry, who, however,—such was Gilbert's popularity in the kingdom,—found it expedient to refrain from any proceedings against him.
At last, in the year 1189, and the 106th of Gilbert's age, his death drew near, and the man of God, full of years, and not less full of grace, prepared to render up his account with joy. He announced to his disciples his approaching departure, and on the evening of Christmas Day he was fortified with the last sacraments of the Church. The remaining time which God vouchsafed him on earth he devoted to the edification of others, and during this time many prelates, and men of various degrees, resorted to him in order to be consoled by his blessing, and instructed by his discourse. The night before the day on which he died "an immense globe of fire, and an appearance as of many candles" were seen to hover in the air over the church of Sempringham, in which his tomb was prepared. Three times the appearance descended from above, rising again twice towards heaven; the third time it penetrated the roof of the church, and descended to the floor. Then the brethren and the nuns knew that the time was at hand when their abbot must indeed leave them.
And so, on the next day, the 3rd of February, he departed this life, amid the sighs and lamentations of all, leaving behind him of religious men about 700, and of sisters in religion 1500; all serving God night and day without ceasing.
He was interred within the church at Sempringham, his tomb being placed between the two choirs, the monks on the one side, and the nuns at the other, so that the religious might offer their prayers at his sepulchre, and continually bearing in mind his holy life and happy death, might both be incited to diligence in prayer and good works, and also might profit by his intercessions for them.
Not long after his death, a certain canon of that order saw in a vision a brother not long since deceased, who, among other things, told him of S. Gilbert: "he is not amongst us, a different place possesses him; for from that place to which he departed (from the world) he has been translated to the choir of the virgins."
