From the psychological perspective, the sources of ACIM increase questions about its validity. Helen Schucman, the primary scribe of the writing, said that the language were dictated to her by an interior style she recognized as Jesus. This process of receiving the writing through internal dictation, referred to as channeling, is often met with skepticism. Critics disagree that channeling could be recognized as a psychological phenomenon rather than authentic spiritual revelation. Schucman himself was a medical psychologist, and some claim that the voice she noticed has been a manifestation of her unconscious brain as opposed to an additional heavenly entity. Moreover, Schucman indicated ambivalence about the work and their roots, sometimes asking their credibility herself. That ambivalence, in conjunction with the method of the text's party, portrays uncertainty on the legitimacy of ACIM as a divinely influenced scripture.

The content of ACIM also invites scrutiny from a philosophical angle. The class shows that the entire world we see with our senses is an illusion and which our true fact lies beyond that physical realm. This idealistic see, which echoes particular Western concepts, issues the materialistic and scientific foundations of American thought. Critics disadavid hoffmeister espanol videos  physical earth can be an dream is not substantiated by scientific evidence and runs counter to the medical strategy, which utilizes visible and measurable phenomena. The notion of an illusory earth may be persuasive as a metaphor for the disturbances of belief caused by the ego, but as a literal assertion, it lacks the scientific support needed to certainly be a valid representation of reality.

Furthermore, the realistic request of ACIM's teachings may be problematic. The class advocates for a radical kind of forgiveness, indicating that grievances are illusions and should be ignored and only recognizing the inherent unity of most beings. While the practice of forgiveness may indeed be therapeutic and transformative, ACIM's method may possibly lead persons to suppress respectable emotions and dismiss true injustices. By framing all negative experiences as illusions produced by the confidence, there is a risk of reducing or invalidating the lived activities of suffering and trauma. That perception may be specially hazardous for persons coping with serious problems such as punishment or oppression, as it can discourage them from seeking the necessary help and interventions.

Another level of rivalry is the way ACIM has been advertised and commercialized. Since its book, ACIM has spawned an important industry of workshops, seminars, and supplementary materials. Critics disagree that commercialization undermines the spiritual strength of the teachings, turning what is purported to be always a sacred text into a profit-driven enterprise. The growth of ACIM-related products and services and solutions has light emitting diode some to issue the motivations behind its campaign and the reliability of those who state to teach their principles. This commercial part can create a buffer to authentic spiritual exploration, as persons might become more centered on buying the following book or participating another class rather than participating profoundly with the teachings themselves.
