Thus were launched these two mendicant orders, which by the enormous following they were so soon to win, were destined to become one of the greatest means of power of the Roman Church.
In the lifetime of their founders the fundamental laws of poverty were observed in all their intended purity. But soon thereafter, being men under their rough habits, and susceptible to the ambition that is man’s, upon the acquisition of power followed the acquisition of wealth. Their founders had accomplished a renascence of the original spirit of Christianity. But soon this began to undergo modification, and to respond to worldly influences, until the history of the friars-mendicant repeats and mirrors the history of Christianity itself. In a measure as they spread through Christendom, so they acquired convents, lands, and property as they went. The personal poverty of each brother remained, it is true; they still went abroad barefoot and coarsely garbed, “without staff, or bag, or bread, or money,” as their rule decreed. Individually they kept the vow of privation; but considered collectively their poverty “remained outside the convent gate,” as Gregorovius says, echoing what Dante had said before him.[17]
For the service of the Church the friars-mendicant became a splendid army, and an army, moreover, whose maintenance made no draught upon the pontifical treasury, since, by virtue of their mendicancy, the orders were entirely self-supporting. And whilst both orders, magnificently organized, grew extremely powerful, the Dominicans became formidable through their control of that Inquisition whose early stirrings had inspired St. Dominic to his task.
His aim had been to found a preaching order whose special mission should be the overthrow of heresy wherever found. The brethren were to combat it, employing their eloquence on the one hand to induce the heretic to abjure his error, on the other to inflame the faithful against him, so that terror should accomplish what might not be possible to persuasion.
It may be that this mission which they had made specially their own, as their founder ordained, peculiarly fitted the Dominicans to assume the government of an ecclesiastical establishment whose aim was identical. It was this order of St. Dominic that was to erect the grim edifice of the Holy Office, and to develop and assume entire control of the terrible machinery of the Inquisition. Their persuasion was to be the ghastly persuasion of the rack; their eloquence was to be the burning eloquence of the tongues of material flame that should lick their agonizing victims out of existence. And all for the love of Christ!
Although it might be difficult to show—as has been attempted—that Domingo de Guzman himself was actually the first ordained Inquisitor, nevertheless as early as 1224, within three years of his death, the Inquisition in Italy and elsewhere was already entirely in the hands of the Dominicans. This is shown by a constitution promulgated at Padua in February of that year by the Emperor Frederic II. It contains the following announcement:
“Be it known to all that we have received under our special protection the preaching friars of the order of preachers, sent into our Empire on business of the Faith against heretics, and likewise all who may lend them assistance—as much in going as in abiding and returning—save such as are already prescribed; and it is our wish that all should give them favour and assistance; wherefore we order our subjects to receive benignly any of the said friars whenever and wherever they may arrive, keeping them secure from the enmity of heretics, assisting them in every way to accomplish their ministry regarding the business of the Faith.... And we do not doubt that you will render homage to God and our Empire by collaborating with the said friars to deliver our Empire from the new and unusual infamy of heretical pravity.”[18]
The constitution decreed that heretics when so condemned by the Church and delivered over to the secular arm should be condignly punished; that if any, through the fear of death, should desire to return to the faith, he should receive the penance that might be imposed canonically and be imprisoned for life; that if in any part of the Empire heretics should be discovered by the inquisitors or by other zealous Catholics, the civil powers should be under the obligation of effecting their arrest at the request of the said inquisitors or other Catholics, and of holding them in safe custody until excommunicated by the Church, when they should be burnt; that the same punishment should be suffered by fautores—i.e. those guilty of concealing or defending heretics; that fugitives be sought for, and that converts from the same heresy be employed to discover them.
