From the psychological point of view, the origins of ACIM raise questions about its validity. Helen Schucman, the principal scribe of the text, claimed that the language were dictated to her by an inner style she recognized as Jesus. This technique of getting the writing through internal dictation, called channeling, is frequently met with skepticism. Critics argue that channeling can be understood as a emotional sensation rather than real spiritual revelation. Schucman herself was a medical psychiatrist, and some declare that the voice she seen might have been a manifestation of her subconscious brain rather than an additional divine entity. Furthermore, Schucman indicated ambivalence about the job and its beginnings, sometimes asking its credibility herself. This ambivalence, in conjunction with the strategy of the text's party, portrays uncertainty on the legitimacy of ACIM as a divinely influenced scripture.

This content of ACIM also invites scrutiny from a philosophical angle. The course teaches that the world we see with our senses is definitely an illusion and which our correct truth lies beyond this bodily realm. This idealistic view, which echoes certain Eastern concepts, difficulties the materialistic and scientific foundations of European thought. Experts disagree that the declare that the physical earth can be an illusion acim audio  is not substantiated by scientific evidence and goes table to the scientific strategy, which utilizes observable and measurable phenomena. The notion of an illusory world may be persuasive as a metaphor for the disturbances of notion due to the ego, but as a literal assertion, it lacks the empirical support required to certainly be a legitimate representation of reality.

Moreover, the practical program of ACIM's teachings can be problematic. The program advocates for a significant kind of forgiveness, suggesting that all issues are illusions and ought to be ignored in favor of realizing the natural unity of all beings. Whilst the exercise of forgiveness may indeed be healing and transformative, ACIM's strategy may lead persons to restrain genuine emotions and dismiss real injustices. By framing all negative experiences as illusions produced by the confidence, there is a danger of reducing or invalidating the existed activities of putting up with and trauma. This perspective could be especially dangerous for individuals dealing with serious dilemmas such as punishment or oppression, as it can discourage them from seeking the mandatory support and interventions.

Still another place of rivalry is the way in which ACIM has been advertised and commercialized. Because their distribution, ACIM has spawned a significant market of workshops, seminars, and supplementary materials. Critics argue that commercialization undermines the spiritual integrity of the teachings, turning what is purported to be always a holy text in to a profit-driven enterprise. The expansion of ACIM-related products and services and services has led some to question the motivations behind its promotion and the credibility of those that declare to instruct their principles. This professional aspect can cause a barrier to true religious exploration, as people might be much more focused on buying the next book or joining the following class rather than engaging deeply with the teachings themselves.
