From the emotional standpoint, the beginnings of ACIM increase issues about its validity. Helen Schucman, the primary scribe of the text, claimed that the language were formed to her by an internal style she determined as Jesus. This technique of obtaining the text through internal dictation, called channeling, is usually achieved with skepticism. Authorities argue that channeling could be recognized as a mental trend rather than real religious revelation. Schucman himself was a medical psychologist, and some suggest that the style she noticed has been a manifestation of her unconscious mind as opposed to an external divine entity. Furthermore, Schucman expressed ambivalence about the job and its sources, occasionally questioning its authenticity herself. This ambivalence, in conjunction with the method of the text's party, portrays doubt on the legitimacy of ACIM as a divinely encouraged scripture.

This content of ACIM also invites scrutiny from the philosophical angle. The program shows that the entire world we perceive with our senses is an illusion and our true reality lies beyond this bodily realm. This idealistic see, which a course in miracles  echoes particular Western philosophies, challenges the materialistic and scientific foundations of Western thought. Experts disagree that the claim that the bodily world can be an dream isn't substantiated by scientific evidence and goes table to the medical technique, which depends on visible and measurable phenomena. The notion of an illusory world might be engaging as a metaphor for the disturbances of notion brought on by the confidence, but as a literal assertion, it lacks the scientific support required to be described as a legitimate illustration of reality.

Moreover, the practical request of ACIM's teachings may be problematic. The program advocates for a radical kind of forgiveness, indicating that all grievances are illusions and should be neglected and only knowing the natural unity of all beings. As the exercise of forgiveness may certainly be healing and major, ACIM's method may possibly lead persons to control reliable feelings and ignore actual injustices. By framing all negative activities as illusions developed by the ego, there is a threat of reducing or invalidating the lived activities of putting up with and trauma. This perception may be specially hazardous for individuals coping with significant problems such as for example abuse or oppression, as it can decrease them from seeking the mandatory support and interventions.

Another position of contention is the way in which ACIM has been advertised and commercialized. Since its publication, ACIM has spawned a substantial industry of workshops, seminars, and supplementary materials. Experts disagree that this commercialization undermines the religious integrity of the teachings, turning what's proposed to be always a holy text right into a profit-driven enterprise. The expansion of ACIM-related services and products and solutions has led some to problem the motivations behind its campaign and the reliability of those that maintain to show its principles. That commercial part can cause a buffer to real religious exploration, as individuals may be much more centered on buying the next book or participating the next workshop as opposed to interesting deeply with the teachings themselves.
