From a psychological viewpoint, the origins of ACIM raise issues about its validity. Helen Schucman, the primary scribe of the writing, stated that the words were dictated to her by an internal voice she discovered as Jesus. This method of obtaining the text through internal dictation, referred to as channeling, is usually met with skepticism. Experts argue that channeling can be understood as a psychological trend rather than a real spiritual revelation. Schucman himself was a clinical psychologist, and some claim that the voice she seen has been a manifestation of her subconscious mind as opposed to an additional heavenly entity. Additionally, Schucman expressed ambivalence about the job and its roots, often asking their credibility herself. That ambivalence, in conjunction with the technique of the text's party, portrays doubt on the legitimacy of ACIM as a divinely encouraged scripture.

This content of ACIM also encourages scrutiny from the philosophical angle. The course teaches that the entire world we perceive with this feelings can be an illusion and our correct reality lies beyond that physical realm. This idealistic see, which echoes certain Eastern philosophies, challenges the materialistic and a course in miracles empirical foundations of American thought. Authorities argue that the declare that the physical world can be an illusion isn't substantiated by scientific evidence and goes table to the clinical approach, which depends on visible and measurable phenomena. The thought of an illusory world may be engaging as a metaphor for the disturbances of understanding caused by the confidence, but as a literal assertion, it lacks the scientific support needed to be described as a valid illustration of reality.

More over, the realistic request of ACIM's teachings can be problematic. The program advocates for a significant type of forgiveness, suggesting that all grievances are illusions and must certanly be ignored in favor of knowing the inherent unity of all beings. Whilst the practice of forgiveness can indeed be healing and major, ACIM's approach may lead persons to control legitimate emotions and dismiss real injustices. By surrounding all bad activities as illusions created by the vanity, there is a risk of reducing or invalidating the existed activities of enduring and trauma. This perspective could be specially harmful for people dealing with significant dilemmas such as abuse or oppression, as it may suppress them from seeking the necessary help and interventions.

Another stage of contention is the way in which ACIM has been sold and commercialized. Because their distribution, ACIM has spawned an important industry of workshops, seminars, and supplementary materials. Experts disagree that commercialization undermines the spiritual strength of the teachings, turning what is purported to become a sacred text in to a profit-driven enterprise. The expansion of ACIM-related items and services has light emitting diode some to issue the motivations behind their promotion and the reliability of those that maintain to teach its principles. That professional aspect can produce a barrier to genuine religious exploration, as persons may become more focused on purchasing the next guide or joining another workshop rather than interesting deeply with the teachings themselves.
