The suggestion that the human psyche (i.e. the intellectual soul) is merely a physical network of chemical reactions is based in the materialistic heresy condemned in the canons of Session III of First Vatican Council published on April 24, 1870. Since this particular aspect of the materialistic heresy deals with the immaterial soul, it implies that the human psyche will die with the material body, that is to say “that the intellectual soul is mortal,” which was condemned in Session VIII of the Fifth Lateran Council in the bull Apostolici Regiminis, published December 19, 1513.
“[T]he Western bio-medical perspective” in which Dr. Carey states “[t]he chemical imbalance idea is firmly rooted,” not only has no scientific support, it relies on two heresies condemned by the Catholic Church. As such, all Catholic bishops who have moral authority over any Catholic hospitals are within their right to ban any practices based on these pseudo-scientific theories just as they ban abortions from such facilities. Since so-called “therapies” resulting from these pseudo-scientific theories cause a reduction in life expectancy and other physical and emotional harm, Catholic bishops with moral authority over Catholic hospitals are obligated to follow the example of Santa Claus in “saving the innocent from death.” Both science and dogma support the banning of these practices from Catholic hospitals.
Although the language in the following text from the Fifth Lateran Council may seem antiquated to modern readers, they should be interpreted as fight’n words:
Since in our days (and we painfully bring this up) the sower of cockle, ancient enemy of the human race, has dared to disseminate and advance in the field of the Lord a number of pernicious errors, always rejected by the faithful, especially concerning the nature of the rational soul, namely, that it is mortal, or one in all men, and some rashly philosophizing affirmed that this is true at least according to philosophy, in our desire to offer suitable remedies against a plague of this kind, with the approval of this holy Council, we condemn and reject all who assert that the intellectual soul is mortal, or is one in all men, and those who cast doubt on these truths, since it [the soul] is not only truly in itself and essentially the form of the human body, as was defined in the canon of Pope CLEMENT V our predecessor of happy memory published in the (general) Council of VIENNE [n. 481] but it is also multiple according to the multitude of bodies into which it is infused, multiplied, and to be multiplied.… And since truth never contradicts truth, we declare [see n. 1797] every assertion contrary to the truth of illumined faith to be altogether false; and, that it may not be permitted to dogmatize otherwise, we strictly forbid it, and we decree that all who adhere to errors of this kind are to be shunned and to be punished as detestable and abominable infidels who disseminate most damnable heresies and who weaken the Catholic faith.
