From the emotional point of view, the roots of ACIM raise issues about their validity. Helen Schucman, the principal scribe of the writing, said that the language were formed to her by an inner style she determined as Jesus. This technique of receiving the writing through internal dictation, known as channeling, is frequently met with skepticism. Authorities disagree that channeling could be recognized as a emotional sensation rather than a true spiritual revelation. Schucman himself was a clinical psychologist, and some declare that the voice she heard might have been a manifestation of her subconscious brain rather than an external heavenly entity. Additionally, Schucman stated ambivalence about the job and their sources, often wondering their authenticity herself. This ambivalence, coupled with the method of the text's party, casts doubt on the legitimacy of ACIM as a divinely encouraged scripture.

This content of ACIM also encourages scrutiny from a philosophical angle. The program teaches that the world we see with this senses is an impression and our correct reality lies beyond that physical realm. That idealistic view, which echoes specific Western philosophies, problems the materialistic and empirical foundations of American thought. Experts argue that  un curso de milagros claim that the bodily world can be an illusion is not substantiated by scientific evidence and operates table to the medical process, which utilizes observable and measurable phenomena. The thought of an illusory earth might be compelling as a metaphor for the disturbances of perception due to the pride, but as a literal assertion, it lacks the scientific support needed to be described as a valid representation of reality.

More over, the realistic application of ACIM's teachings can be problematic. The program advocates for a radical kind of forgiveness, indicating that all issues are illusions and should be overlooked in favor of knowing the natural unity of beings. While the practice of forgiveness may certainly be healing and major, ACIM's approach may possibly cause people to curb respectable emotions and dismiss real injustices. By surrounding all negative experiences as illusions produced by the pride, there's a threat of minimizing or invalidating the existed experiences of suffering and trauma. That perception may be especially harmful for people working with serious issues such as for example punishment or oppression, as it may decrease them from seeking the required help and interventions.

Another place of competition is the way in which ACIM has been promoted and commercialized. Since its publication, ACIM has spawned a significant market of workshops, seminars, and supplementary materials. Critics fight this commercialization undermines the spiritual integrity of the teachings, turning what is purported to become a holy text into a profit-driven enterprise. The expansion of ACIM-related services and products and solutions has led some to issue the motivations behind its campaign and the credibility of those who maintain to instruct their principles. This commercial element can make a barrier to genuine religious exploration, as individuals may possibly be more dedicated to getting the next book or participating the next workshop rather than interesting profoundly with the teachings themselves.
