God's Will created us in His image, and this includes & requires a soul that is at all times free-willed and responsible and logical, and includes that there is no free will without logical operation..

There is Christian heresy in the idea of 'psyche', and it is heresy of the most major & destructive nature which undermines dogmas & commandments at their cores through the idolatrous creation of the equivalent of a false god [first commandment violation:  "You shall have no gods except Me."], and through the dilution of ones primary responsibility to only God in all decisions and especially in all that relates to God & His requirements [second
commandment violation:  no diversion or dilution of leadership/authority to subset intermediaries, nor imprecision of responsibility/guilt in the carrying out of God's Will & repair of the damages of sin, such as via referral to a so-called psyche or mental illness, or raising of alternative goals/idols -- like family/race/class/nation/patriotism/language/religion/fraternity/culture/etc. as excuses to fully or partially set-aside God's Will: "You shall not make unto youlself a carved image or any likeness of anything in heaven or on earth or in the waters under the earth; you shall not bow down to them nor serve them.  For I, Yahweh your God, am a jealous God and I punish the father's fault in the sons, the grandsons, and the great-grandsons of those who hate Me; but I show kindness to thousands of those who love Me and keep My commandments."] and which heresy may rightly be labeled as the cornerstone heresy of anti-responsibility/anti-guilt/anti-freewill/anti-life/anti-Christianity, and so for which it is heresy on the Magisterium of the Church to:
              a.  affirm belief in a duality of competence/control involving the mind and/or will, and especially in that manner which is commonly understood as operative in the term 'psyche' [and in the other derivative terms associated with the cult of the psyche], and which belief does in fact inherently always require belief in a duality of competence/control with associative affirmation [intended or not] of the mind's or soul's lack [or critical reduction of the cores] of essential control [and so loss of moral & personal responsibility -- which word/idea (responsibility) is not the same as self-dependence; may be physically dependent on others, but still be personally responsible in all choices] over critical mental functions; as well as to
              b.  affirm belief in the possibility of the mind's not performing competently & logically at all times [even  when brain may be  subject to major inefficiencies due to  injury, disease, toxins, deficiencies of chemicals/nutrients, etc.:   legitimate "diminished capacity" -- mind operating logically with what facts/data it has available, but significant facts/data just not available due to some one or more of these causes], or belief in the critical reduction of the essentials of that performance of the mind  [and so critical reduction of moral & personal responsibility] and which belief is in fact
always inherent in the terms 'mental health' and 'mental illness'.
