From a psychological standpoint, the origins of ACIM raise issues about their validity. Helen Schucman, the principal scribe of the text, claimed that what were dictated to her by an interior voice she determined as Jesus. This technique of getting the writing through internal dictation, called channeling, is frequently met with skepticism. Experts fight that channeling can be understood as a psychological sensation rather than a authentic spiritual revelation. Schucman herself was a scientific psychiatrist, and some suggest that the voice she noticed might have been a manifestation of her subconscious brain as opposed to an external divine entity. Moreover, Schucman expressed ambivalence about the task and its beginnings, sometimes questioning their credibility herself. That ambivalence, along with the strategy of the text's reception, portrays uncertainty on the legitimacy of ACIM as a divinely encouraged scripture.

The content of ACIM also invites scrutiny from the philosophical angle. The class shows that the world we comprehend with our feelings can be an impression and which our correct truth lies beyond this bodily realm. This idealistic view, which echoes specific Eastern ideas, problems the materialistic and empirical foundations of European thought. Authorities argue that the declare that the bodily earth is an illusion the christ  isn't substantiated by scientific evidence and runs counter to the scientific approach, which relies on observable and measurable phenomena. The thought of an illusory earth may be engaging as a metaphor for the disturbances of notion brought on by the vanity, but as a literal assertion, it lacks the empirical support required to be considered a valid illustration of reality.

Furthermore, the realistic request of ACIM's teachings may be problematic. The course advocates for a radical kind of forgiveness, indicating that issues are illusions and should be overlooked in support of realizing the inherent unity of beings. While the practice of forgiveness may indeed be healing and major, ACIM's strategy may possibly lead individuals to suppress genuine thoughts and ignore true injustices. By mounting all bad activities as illusions created by the pride, there is a danger of minimizing or invalidating the existed activities of suffering and trauma. That perception may be specially dangerous for persons working with significant issues such as for instance punishment or oppression, as it can discourage them from seeking the mandatory help and interventions.

Another point of competition is just how ACIM has been promoted and commercialized. Since its distribution, ACIM has spawned an important business of workshops, seminars, and supplementary materials. Experts fight this commercialization undermines the religious reliability of the teachings, turning what's purported to be a holy text into a profit-driven enterprise. The expansion of ACIM-related products and companies has light emitting diode some to issue the motivations behind its promotion and the credibility of those who claim to show its principles. That commercial aspect can make a barrier to genuine religious exploration, as individuals might be more centered on buying the next book or participating the next workshop rather than engaging deeply with the teachings themselves.
