manner, we hereby declare that in addition to the penalties and censures contained in the Constitutions issued by Sixtus IV to which we want them to be subjected and to which we subject them by the present Constitution, we hereby decree that they be deprived of the authority of preaching, reading in public, that is to say teaching and interpreting; and that they be also deprived ipso facto of the power of voting, either actively or passively, in all elections, without the need for any further declaration; and that also, ipso facto, without any further declaration, they shall incur the penalty of perpetual disability from preaching, reading in public, teaching and interpreting, and that it shall not be possible to absolve them from such penalty, or remove it, save through ourselves, or the Roman Pontiffs who shall succeed us.
"We also require that the same shall remain subject to any other penalties which by us, of our own free will -- or by the Roman Pontiffs, our successors (according as they may decree) -- shall be deemed advisable to establish, and by the present Constitution we declare them subject thereto, and hereby renew the above Decrees and Constitutions of Paul V and Gregory XV.
"Moreover, as regards those books in which the said sentence, feast and relative veneration are called into question or are contradicted in any way whatsoever, according to what has already been stated, either in writing or verbally, in discourses, sermons, lectures, treatises and debates -- that may have been printed after the above-praised Decree of Paul V, or may be printed hereafter we hereby prohibit them, subject to the penalties and censures established by the Index of prohibited books, and ipso facto, without any further declaration, we desire and command that they be held as expressly prohibited."

Testimonies of the Catholic World
All are aware with how much diligence this doctrine of the Immaculate Conception of the Mother of God has been handed down, proposed and defended by the most outstanding religious orders, by the more celebrated theological academies, and by very eminent doctors in the sciences of theology. All know, likewise, how eager the bishops have been to profess openly and publicly, even in ecclesiastical assemblies, that Mary, the most holy Mother of God, by virtue of the foreseen merits of Christ, our Lord and Redeemer, was never subject to original sin, but was completely preserved from the original taint, and hence she was redeemed in a manner more sublime.
The Council of Trent
Besides, we must note a fact of the greatest

importance indeed. Even the Council of Trent itself, when it promulgated the dogmatic decree concerning original sin, following the testimonies of the Sacred Scriptures, of the Holy Fathers and of the renowned Council, decreed and defined that all men are born infected by original sin; nevertheless, it solemnly declared that it had no intention of including the blessed and immaculate Virgin Mary, the Mother of God, in this decree and in the general extension of its definition. Indeed, considering the times and circumstances, the Fathers of Trent sufficiently intimated by this declaration that the Blessed Virgin Mary was free from the original stain; and thus they clearly signified that nothing could be reasonably cited from the Sacred Scriptures, from Tradition, or from the authority of the Fathers, which would in any way be opposed to so great a prerogative of the Blessed Virgin. [12]
Testimonies of Tradition
And indeed, illustrious documents of venerable antiquity, of both the Eastern and the Western Church, very forcibly testify that this doctrine of the Immaculate Conception of the most Blessed Virgin, which was daily more and more splendidly explained, stated and confirmed by the highest authority, teaching, zeal, knowledge, and wisdom of the Church, and which was disseminated among all peoples and nations of the Catholic world in a marvellous manner -- this doctrine always existed in the Church as a doctrine that has been received from our ancestors, and that has been stamped with the character of revealed doctrine. For the Church of Christ, watchful guardian that she is, and defender of the dogmas deposited with her, never changes anything, never diminishes anything, never adds anything to them; but with all diligence she treats the ancient documents faithfully and wisely; if they really are of ancient origin and if the faith of the Fathers has transmitted them, she strives to investigate and explain them in such a way that the ancient dogmas of heavenly doctrine will be made evident and clear, but will retain their full, integral, and proper nature, and will grown only within their own genus -- that is, within the same dogma, in the same sense and the same meaning.
Interpreters of the Sacred Scripture
The Fathers and writers of the Church, well versed in the heavenly Scriptures, had nothing more at heart than to vie with one another in preaching and teaching in many wonderful ways the Virgin's supreme sanctity, dignity, and immunity from all stain of sin, and her renowned victory over the most foul enemy of the human race. This they did in the books they wrote to
