The professional aspects of ACIM also ask skepticism. Since its publication, the class has spawned a multi-million dollar market which includes publications, workshops, seminars, and on the web courses. Experts disagree that the commercialization of ACIM undermines their spiritual concept and increases ethical issues in regards to the motivations of those that promote it. The large prices associated with participating in ACIM-related actions can be prohibitive for most, ultimately causing accusations that the class is more focused on revenue than on true religious growth. This commercialization is visible as exploiting the spiritual wants and vulnerabilities of people for economic gain.

Furthermore, the language and framework of ACIM in many cases are criticized to be very complex and esoteric. The course's heavy and repetitive prose could be complicated to comprehend and interpret, ultimately causing distress and misinterpretation among readers. This difficulty can produce a buffer to access, which makes it difficult for people to fully interact with and take advantage of the course. Some critics fight that the convoluted language is really a strategic tactic to hidden the lack of substantive material and to create an impression of profundity. The difficulty in comprehending the product may also result in a dependence on outside educators and interpreters, further perpetuating the commercialization and prospect of exploitation within the ACIM community.

Also, the notion of forgiveness as shown in ACIM has been criticized to be very easy and possibly dismissive of actual damage and injustice. The class advocates for a questionnaire of forgiveness that requires realizing the illusory character of the observed offense and making go of grievances. While this process can be helpful in selling internal peace and lowering personal enduring, it could not acceptably handle the complexities of particular situations, such as for instance  acim app or systemic injustice. Authorities argue this kind of forgiveness is seen as reducing the activities of patients and absolving perpetrators of accountability. This will cause a questionnaire of religious skipping, where individuals use religious ideas to avoid coping with unpleasant thoughts and hard realities.

The general worldview presented by ACIM, which stresses the illusory character of the product world and the pride, can also be problematic. That perspective can cause a form of religious escapism, where people disengage from the bodily earth and their challenges and only an idealized spiritual reality. While this can give short-term comfort or even a feeling of transcendence, it can also cause a not enough proposal with important facets of living, such as associations, responsibilities, and cultural issues. Critics fight that disengagement can be detrimental to equally the average person and culture, because it advances a questionnaire of passivity and neglect of real-world problems.
