One of the principal evaluations of ACIM is their source story and the statements produced by their proposed writer, Helen Schucman. Schucman, a clinical psychiatrist, stated that this content of the program was determined to her by an internal voice she determined as Jesus Christ. This account alone improves issues about the standing of the text, as it relies heavily on a subjective and unverifiable experience. Experts disagree that the whole foundation of ACIM is founded on a personal thought that cannot be substantiated by scientific evidence or external validation. This not enough verifiability helps it be difficult to simply accept the program as a legitimate spiritual or mental guide.

More over, this content of ACIM diverges significantly from standard Religious teachings, despite their regular recommendations to Christian acim terminology and concepts. The course reinterprets critical facets of Christianity, including the character of failure, salvation, and the position of Jesus Christ. For instance, ACIM teaches that failure is not true and that salvation is achieved through a modify in understanding rather than through the atoning sacrifice of Jesus. This reinterpretation can be seen as difficult for those who abide by orthodox Christian values, since it fundamentally alters the key tenets of their faith. The divergence from conventional doctrine has led many Religious scholars to ignore ACIM as heretical or misleading.

The psychological influence of ACIM on its adherents is still another area of concern. While the program claims inner peace and religious enlightenment, some psychological wellness professionals have increased alerts about its possible to trigger confusion, disillusionment, and also emotional harm. The course's emphasis on the illusory nature of the material earth and the confidence may lead individuals to question the truth of the experiences and thoughts in ways that might not be beneficial. For many, this pondering can result in a declined capacity to cope with real-world issues and associations, leading to solitude and a feeling of detachment from life. Experts argue that this method could be especially dangerous for people who are presently weak or experiencing emotional wellness issues.

Still another place of review is having less empirical help for the claims produced by ACIM. The program asserts that its teachings can result in profound religious change and healing, but these statements are not reinforced by medical study or clinical studies. Without empirical evidence to back up its assertions, ACIM relies heavily on anecdotal evidence and particular testimonials, which are inherently subjective and unreliable. The possible lack of demanding, objective study causes it to be difficult to ascertain the real efficacy of the program and increases questions about its overall legitimacy.
