Additionally, the information of ACIM diverges considerably from traditional Christian teachings, despite their frequent referrals to Christian terminology and concepts. The class reinterprets crucial facets of Christianity, such as the nature of sin, salvation, and the position of Jesus Christ. For instance, ACIM teaches that sin is not true and that salvation is achieved through a change in perception as opposed to through the atoning sacrifice of Jesus. That reinterpretation is visible as difficult for people who abide by orthodox Religious beliefs, since it fundamentally alters the primary tenets of their faith. The divergence from traditional doctrine has led many Christian scholars to ignore ACIM as heretical or misleading.

The emotional impact of ACIM on their adherents is still another part of concern. While the class promises inner peace and religious enlightenment, some psychological wellness professionals have raised acim audio alerts about their possible to trigger distress, disillusionment, and actually psychological harm. The course's emphasis on the illusory nature of the substance world and the ego may lead persons to question the fact of these experiences and feelings in techniques may not be beneficial. For a few, that pondering may result in a diminished volume to cope with real-world issues and relationships, leading to isolation and a sense of detachment from life. Authorities disagree that this strategy could be particularly dangerous for persons who are currently vulnerable or fighting emotional wellness issues.

Yet another level of review is the lack of scientific support for the states made by ACIM. The course asserts that its teachings may cause profound spiritual change and healing, but these states aren't supported by clinical study or scientific studies. Without empirical evidence to back up its assertions, ACIM relies greatly on historical evidence and personal testimonials, which are inherently subjective and unreliable. Having less demanding, objective study causes it to be hard to determine the true efficiency of the class and raises issues about their overall legitimacy.

The industrial aspects of ACIM also ask skepticism. Since their book, the program has spawned a multi-million buck business which includes publications, workshops, seminars, and online courses. Experts disagree that the commercialization of ACIM undermines their spiritual message and increases ethical issues in regards to the motivations of people who promote it. The high charges related to participating in ACIM-related activities can be prohibitive for most, leading to accusations that the program is more dedicated to gain than on authentic spiritual growth. This commercialization is visible as exploiting the religious needs and vulnerabilities of people for financial gain.
