From a psychological standpoint, the origins of ACIM raise issues about its validity. Helen Schucman, the principal scribe of the text, claimed that what were dictated to her by an inner voice she determined as Jesus. This method of obtaining the writing through internal dictation, known as channeling, is frequently met with skepticism. Authorities disagree that channeling can be recognized as a mental trend rather than true spiritual revelation. Schucman herself was a scientific psychiatrist, and some suggest that the style she heard might have been a manifestation of her unconscious brain rather than an additional heavenly entity. Additionally, Schucman expressed ambivalence about the job and its roots, sometimes asking their credibility herself. That ambivalence, coupled with the method of the text's party, portrays uncertainty on the legitimacy of ACIM as a divinely influenced scripture.

This content of ACIM also encourages scrutiny from a philosophical angle. The program shows that the planet we comprehend with our senses can be an dream and which our true truth lies beyond this physical realm. This idealistic see, which echoes certain Eastern philosophies, issues the materialistic and scientific foundations of European thought. Critics disagree david hoffmeister  that the claim that the bodily earth can be an illusion isn't substantiated by empirical evidence and goes table to the clinical process, which depends on visible and measurable phenomena. The thought of an illusory world might be powerful as a metaphor for the disturbances of perception due to the ego, but as a literal assertion, it lacks the empirical support needed to be considered a valid representation of reality.

Furthermore, the useful request of ACIM's teachings could be problematic. The course advocates for a radical kind of forgiveness, indicating that issues are illusions and ought to be overlooked in favor of recognizing the natural unity of most beings. Whilst the exercise of forgiveness may certainly be healing and transformative, ACIM's approach may possibly cause persons to suppress genuine emotions and ignore true injustices. By surrounding all bad activities as illusions created by the confidence, there's a threat of minimizing or invalidating the existed experiences of putting up with and trauma. That perception could be particularly hazardous for individuals working with significant problems such as abuse or oppression, as it may decrease them from seeking the required support and interventions.

Still another point of argument is the way in which ACIM has been sold and commercialized. Because their publication, ACIM has spawned an important business of workshops, seminars, and supplementary materials. Critics argue this commercialization undermines the spiritual integrity of the teachings, turning what is supposed to be always a holy text in to a profit-driven enterprise. The expansion of ACIM-related products and solutions has led some to problem the motivations behind their campaign and the authenticity of people who maintain to instruct their principles. This professional aspect can make a barrier to authentic religious exploration, as people might be much more focused on purchasing the next guide or participating the following workshop as opposed to engaging deeply with the teachings themselves.
