One of the principal opinions of ACIM is their source story and the claims created by its proposed writer, Helen Schucman. Schucman, a scientific psychologist, said that the information of the program was determined to her by an interior style she identified as Jesus Christ. This narrative alone raises issues concerning the credibility of the writing, since it relies heavily on a subjective and unverifiable experience. Experts disagree that the whole foundation of ACIM is founded on your own discovery that cannot be substantiated by empirical evidence or external validation. That insufficient verifiability causes it to be difficult to just accept the program as the best spiritual or emotional guide.

Furthermore, this content of ACIM diverges significantly from traditional Religious teachings, despite its regular referrals to Christian terminology and concepts. The class david hoffmeister reinterprets key facets of Christianity, such as the character of failure, salvation, and the position of Jesus Christ. For example, ACIM teaches that sin is not true and that salvation is accomplished via a change in notion as opposed to through the atoning compromise of Jesus. This reinterpretation is visible as problematic for individuals who abide by orthodox Christian beliefs, because it fundamentally alters the primary tenets of their faith. The divergence from standard doctrine has led several Christian scholars to ignore ACIM as heretical or misleading.

The psychological impact of ACIM on its adherents is still another part of concern. While the course claims inner peace and spiritual enlightenment, some emotional wellness professionals have elevated alerts about their possible to cause confusion, disillusionment, and actually psychological harm. The course's focus on the illusory nature of the product world and the confidence may lead people to issue the fact of their experiences and thoughts in methods may possibly not be beneficial. For a few, that wondering can lead to a reduced volume to manage real-world issues and associations, leading to isolation and a feeling of detachment from life. Experts fight that this method can be specially harmful for people that are currently weak or struggling with psychological health issues.

Yet another stage of critique is the possible lack of empirical help for the claims created by ACIM. The program asserts that their teachings can result in profound spiritual transformation and therapeutic, but these states are not reinforced by medical research or scientific studies. Without empirical evidence to right back up its assertions, ACIM relies seriously on historical evidence and particular testimonies, which are inherently subjective and unreliable. The possible lack of arduous, purpose study makes it hard to determine the real usefulness of the program and raises questions about its overall legitimacy.
