More over, the information of ACIM diverges somewhat from traditional Religious teachings, despite their repeated referrals to Religious terminology and concepts. The program reinterprets key areas of Christianity, such as the nature of crime, salvation, and the role of Jesus Christ. For example, ACIM shows that crime is not real and that salvation is reached via a modify in perception rather than through the atoning compromise of Jesus. This reinterpretation is visible as problematic for individuals who abide by orthodox Christian beliefs, since it fundamentally alters the primary tenets of the faith. The divergence from conventional doctrine has light emitting diode several Christian scholars to ignore ACIM as heretical or misleading.

The psychological impact of ACIM on their adherents is another part of concern. As the course promises inner peace and religious enlightenment, some intellectual health experts have elevated sensors about its potential to trigger frustration, disillusionment, and also mental harm. The course's increased exposure of the illusory nature of the product world and the confidence may cause persons to problem the reality of the activities and thoughts in techniques might not be beneficial. For a few, that asking acim can result in a decreased capacity to manage real-world problems and associations, leading to solitude and a sense of detachment from life. Critics fight that this kind of strategy can be especially harmful for individuals that are presently weak or struggling with emotional health issues.

Still another level of critique is having less scientific support for the states created by ACIM. The program asserts that its teachings can result in profound religious transformation and therapeutic, but these claims are not supported by medical study or clinical studies. Without empirical evidence to straight back up its assertions, ACIM relies heavily on anecdotal evidence and particular testimonies, which are inherently subjective and unreliable. The lack of rigorous, aim study makes it hard to establish the real efficacy of the class and raises issues about their overall legitimacy.

The industrial aspects of ACIM also invite skepticism. Since its book, the class has spawned a multi-million money industry that includes publications, workshops, seminars, and online courses. Critics argue that the commercialization of ACIM undermines its spiritual concept and raises moral issues in regards to the motivations of people who promote it. The large costs connected with participating in ACIM-related actions may be high for a lot of, ultimately causing 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 an individual for economic gain.
