In Ineffabilus Deus, Pope Pius IX’s declaration of the Immaculate Conception (the idea that Mary was born without original sin), the Pope referred to sanctions issued by previous Popes, forbidding interpreting scripture or the fathers in a way other than clearly asserting the Immaculate Conception.1 He then commissions a study by numbers scholars to get their opinion on the Immaculate Conception. 2 Of course, they are forbidden from giving him any other answer then the one he wants them to give. There are a rot of problems with this approach, but one of them is that people’s opinions are inherently personal and ultimately can’t be outsourced.
1 "And therefore, against all and everyone of those who shall continue to construe the said Constitutions and Decrees in a manner apt to frustrate the favor which is thereby given to the said doctrine, and to the feast and relative veneration, or who shall dare to call into question the said sentence, feast and worship, or in any way whatever, directly or indirectly, shall declare themselves opposed to it under any pretext whatsoever, were it but only to the extent of examining the possibilities of effecting the definition, or who shall comment upon and interpret the Sacred Scripture, or the Fathers or Doctors in connection therewith, or finally, for any reason, or on any occasion, shall dare, either in writing or verbally, to speak, preach, treat, dispute or determine upon, or assert whatsoever against the foregoing matters, or who shall adduce any arguments against them, while leaving them unresolved, or who shall disagree therewith in any other conceivable 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.

2 That we might proceed with great prudence, we established a special congregation of our venerable brethren, the cardinals of the holy Roman Church, illustrious for their piety, wisdom, and knowledge of the sacred scriptures. We also selected priests, both secular and regular, well trained in the theological sciences, that they should most carefully consider all matters pertaining to the Immaculate Conception of the Virgin and make known to us their opinion.
