From the emotional point of view, the beginnings of ACIM increase issues about its validity. Helen Schucman, the primary scribe of the text, claimed that the words were dictated to her by an interior voice she identified as Jesus. This method of obtaining the writing through internal dictation, referred to as channeling, is usually achieved with skepticism. Experts fight that channeling can be understood as a emotional trend rather than a real religious revelation. Schucman himself was a scientific psychiatrist, and some claim that the voice she seen has been a manifestation of her subconscious mind as opposed to an external divine entity. Additionally, Schucman expressed ambivalence about the job and its roots, often asking its reliability herself. This ambivalence, along with the technique of the text's party, casts doubt on the legitimacy of ACIM as a divinely inspired scripture.

The content of ACIM also invites scrutiny from the philosophical angle. The course shows that the world we see with this feelings can be an dream and which our correct truth lies beyond this bodily realm. This idealistic view, which echoes specific Western ideas, problems the materialistic and scientific foundations of European thought. Experts argue that the acim  claim that the physical earth is an illusion is not substantiated by empirical evidence and works counter to the scientific approach, which depends on observable and measurable phenomena. The notion of an illusory earth might be powerful as a metaphor for the disturbances of belief brought on by the confidence, but as a literal assertion, it lacks the scientific support necessary to be considered a valid illustration of reality.

More over, the realistic application of ACIM's teachings can be problematic. The course advocates for a revolutionary type of forgiveness, suggesting that issues are illusions and ought to be ignored and only realizing the inherent unity of most beings. Whilst the training of forgiveness can indeed be therapeutic and major, ACIM's method may cause persons to restrain legitimate thoughts and ignore real injustices. By mounting all bad activities as illusions created by the pride, there is a danger of reducing or invalidating the existed activities of enduring and trauma. This perception can be particularly hazardous for persons dealing with significant dilemmas such as for instance punishment or oppression, as it can suppress them from seeking the mandatory support and interventions.

Another stage of competition is just how ACIM has been marketed and commercialized. Because its distribution, ACIM has spawned a substantial business of workshops, seminars, and supplementary materials. Experts argue that this commercialization undermines the religious strength of the teachings, turning what's purported to be always a holy text in to a profit-driven enterprise. The growth of ACIM-related products and solutions has light emitting diode some to question the motivations behind their campaign and the authenticity of those who declare to show their principles. That commercial aspect can cause a buffer to real spiritual exploration, as people may become more dedicated to buying the next book or participating the following seminar rather than engaging profoundly with the teachings themselves.
