One of many principal evaluations of ACIM is their source history and the states produced by their supposed author, Helen Schucman. Schucman, a medical psychiatrist, stated that the content of the class was dictated to her by an internal voice she discovered as Jesus Christ. That account alone improves issues about the standing of the writing, because it relies greatly on a subjective and unverifiable experience. Experts argue that the entire basis of ACIM is based on your own discovery that can not be substantiated by scientific evidence or additional validation. This lack of verifiability makes it difficult to just accept the course as the best spiritual or psychological guide.

Moreover, the content of ACIM diverges considerably from traditional Religious teachings, despite its regular referrals to Religious terminology acim and concepts. The program reinterprets crucial aspects of Christianity, such as the character of failure, salvation, and the role of Jesus Christ. For instance, ACIM shows that sin is not true and that salvation is reached through a change in notion rather than through the atoning compromise of Jesus. That reinterpretation can be seen as problematic for individuals who stick to orthodox Christian values, as it fundamentally alters the primary tenets of the 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 yet another area of concern. Whilst the course promises internal peace and spiritual enlightenment, some mental wellness specialists have elevated alarms about its possible to trigger distress, disillusionment, and also psychological harm. The course's increased exposure of the illusory nature of the product world and the confidence may lead individuals to question the fact of their experiences and emotions in techniques might not be beneficial. For some, this pondering can lead to a declined capacity to deal with real-world problems and relationships, ultimately causing solitude and a feeling of detachment from life. Critics disagree that this strategy could be specially harmful for persons who are currently weak or fighting intellectual wellness issues.

Still another place of review is having less empirical support for the states created by ACIM. The course asserts that their teachings may lead to profound religious transformation and healing, but these statements are not supported by medical study or clinical studies. Without scientific evidence to back up their assertions, ACIM relies heavily on historical evidence and personal testimonials, which are inherently subjective and unreliable. The possible lack of rigorous, purpose study helps it be hard to establish the real usefulness of the class and raises issues about their overall legitimacy.
