From a emotional standpoint, the sources of ACIM increase issues about their validity. Helen Schucman, the principal scribe of the writing, said that the language were dictated to her by an inner voice she recognized as Jesus. This process of receiving the writing through inner dictation, referred to as channeling, is often met with skepticism. Authorities fight that channeling can be understood as a mental trend rather than true religious revelation. Schucman himself was a medical psychologist, and some suggest that the style she noticed may have been a manifestation of her subconscious brain as opposed to an additional heavenly entity. Moreover, Schucman stated ambivalence about the job and its beginnings, occasionally asking their credibility herself. That ambivalence, coupled with the technique of the text's reception, portrays doubt on the legitimacy of ACIM as a divinely inspired scripture.

This content of ACIM also invites scrutiny from a philosophical angle. The program teaches that the world we perceive with our feelings can be an impression and our true truth lies beyond that bodily realm. That idealistic see, which echoes certain Eastern concepts, issues the materialistic and scientific foundations of American thought. Experts disagree that the declare that the bodily earth can be an illusion is not substantiated by scientific evidence and runs table to the medical process, which depends on visible and   david hoffmeiste measurable phenomena. The notion of an illusory world may be convincing as a metaphor for the distortions of perception due to the pride, but as a literal assertion, it lacks the empirical support required to be considered a legitimate representation of reality.

Furthermore, the sensible program of ACIM's teachings may be problematic. The course advocates for a significant type of forgiveness, suggesting that most grievances are illusions and ought to be overlooked and only recognizing the natural unity of all beings. While the practice of forgiveness can indeed be therapeutic and major, ACIM's approach might cause individuals to restrain genuine feelings and dismiss real injustices. By surrounding all bad experiences as illusions developed by the ego, there is a threat of minimizing or invalidating the existed experiences of enduring and trauma. This perspective can be especially harmful for people dealing with critical issues such as punishment or oppression, as it may decrease them from seeking the mandatory support and interventions.

Yet another stage of argument is the way ACIM has been promoted and commercialized. Since its book, ACIM has spawned a significant business of workshops, seminars, and supplementary materials. Experts fight that this commercialization undermines the spiritual integrity of the teachings, turning what's purported to be a holy text into a profit-driven enterprise. The proliferation of ACIM-related services and products and services has led some to question the motivations behind its campaign and the credibility of those that maintain to instruct its principles. That professional element can produce a barrier to true spiritual exploration, as individuals may be much more dedicated to buying another book or joining the next class rather than participating profoundly with the teachings themselves.
