Furthermore, the content of ACIM diverges somewhat from traditional Christian teachings, despite their regular sources to Religious terminology and concepts. The class reinterprets critical facets of Christianity, such as the nature of failure, salvation, and the role of Jesus Christ. For instance, ACIM teaches that sin is not real and that salvation is accomplished via a change in belief as opposed to through the atoning sacrifice of Jesus. This reinterpretation is seen as difficult for those who adhere to orthodox Christian beliefs, since it fundamentally alters the primary tenets of these faith. The divergence from old-fashioned doctrine has led several Religious scholars to dismiss ACIM as heretical or misleading.

The mental influence of ACIM on its adherents is another part of concern. As the class claims internal peace and spiritual enlightenment, some psychological health specialists have increased alerts about their possible to trigger confusion, disillusionment, and actually psychological harm. The course's emphasis on the illusory character of the substance earth and the confidence can lead persons to question the truth of these activities and feelings in ways that may possibly not be beneficial. For a few, this asking may result in a reduced capacity to deal with real-world problems and relationships, leading to isolation and a feeling of detachment from life. Critics disagree that such an approach can be particularly dangerous for persons who are presently vulnerable or struggling with intellectual wellness issues.

Still another place of review is the possible lack of scientific help for the states made by ACIM. The course asserts that its teachings may lead to profound spiritual change and therapeutic, but these states are not reinforced by clinical study or scientific a course in miracles studies. Without scientific evidence to right back up its assertions, ACIM relies greatly on historical evidence and particular recommendations, which are inherently subjective and unreliable. The possible lack of arduous, objective research causes it to be hard to confirm the actual effectiveness of the class and increases questions about its over all legitimacy.

The industrial areas of ACIM also invite skepticism. Because its book, the class has spawned a multi-million buck industry that features publications, workshops, seminars, and on line courses. Authorities argue that the commercialization of ACIM undermines its religious meaning and improves honest issues about the motivations of those that promote it. The high costs associated with participating in ACIM-related actions may be prohibitive for most, resulting in accusations that the course is more focused on revenue than on true spiritual growth. This commercialization can be seen as exploiting the spiritual needs and vulnerabilities of individuals for financial gain.

More over, the language and framework of ACIM are often criticized for being excessively complicated and esoteric. The course's thick and repeated prose may be complicated to know and understand, leading to distress and misinterpretation among readers. That complexity can create a buffer to access, rendering it problematic for people to completely engage with and benefit from the course. Some authorities disagree that the complicated language is really a deliberate tactic to hidden having less substantive content and to create an impression of profundity. The difficulty in comprehending the material may also result in a reliance on additional educators and interpreters, further perpetuating the commercialization and possibility of exploitation within the ACIM community.
