From a psychological perspective, the origins of ACIM increase issues about their validity. Helen Schucman, the principal scribe of the text, claimed that the language were formed to her by an interior voice she identified as Jesus. This method of obtaining the writing through internal dictation, called channeling, is usually met with skepticism. Experts argue that channeling may be understood as a emotional phenomenon rather than genuine religious revelation. Schucman himself was a clinical psychologist, and some declare that the voice she noticed might have been a manifestation of her subconscious mind rather than an external heavenly entity. Also, Schucman stated ambivalence about the job and its beginnings, sometimes asking its reliability herself. That ambivalence, in conjunction with the strategy of the text's party, portrays uncertainty on the legitimacy of ACIM as a divinely encouraged scripture.

This content of ACIM also encourages scrutiny from a philosophical angle. The course shows that the world we comprehend with our feelings can be an illusion and that our correct reality lies beyond this physical realm. That idealistic see, which echoes certain Eastern concepts, challenges the materialistic and scientific a course in miracles podcast foundations of European thought. Authorities argue that the claim that the bodily world can be an impression is not substantiated by scientific evidence and operates counter to the scientific approach, which depends on visible and measurable phenomena. The notion of an illusory earth may be convincing as a metaphor for the disturbances of belief caused by the confidence, but as a literal assertion, it lacks the empirical support necessary to certainly be a legitimate illustration of reality.

Furthermore, the realistic application of ACIM's teachings can be problematic. The course advocates for a revolutionary kind of forgiveness, indicating that most issues are illusions and must be neglected and only knowing the natural unity of all beings. Whilst the exercise of forgiveness can indeed be therapeutic and transformative, ACIM's method might lead persons to control reliable emotions and ignore real injustices. By mounting all bad experiences as illusions created by the confidence, there is a risk of reducing or invalidating the lived activities of suffering and trauma. This perception can be specially dangerous for individuals coping with critical problems such as abuse or oppression, as it may decrease them from seeking the required support and interventions.

Another stage of rivalry is the way in which ACIM has been promoted and commercialized. Because their distribution, ACIM has spawned a significant business of workshops, seminars, and supplementary materials. Critics fight that this commercialization undermines the spiritual strength of the teachings, turning what's proposed to be a sacred text in to a profit-driven enterprise. The proliferation of ACIM-related products and services and services has light emitting diode some to problem the motivations behind its campaign and the credibility of people who claim to instruct their principles. That professional element can make a barrier to real religious exploration, as persons might be much more centered on purchasing the following guide or participating another class as opposed to participating profoundly with the teachings themselves.
