The practical software of ACIM's teachings can also be a place of contention. Although some people report good transformations and personal growth from following the program, the others get the practices to be useless or even harmful. The course's emphasis on forgiveness and enjoy is remarkable, but critics disagree that it can be excessively simplified and naïve, declining to handle the difficulties of individual associations and the need for boundaries and accountability. Additionally, the course's size and rigorous character may be frustrating for some people, ultimately causing burnout or disillusionment. Authorities declare that enough time and effort expected to accomplish ACIM could be better allocated to more empirically supported beneficial methods or spiritual professions that have an established track record of effectiveness.

The broader impact of ACIM on the spiritual and self-help towns can be worth considering. The course has encouraged a substantial following and has been incorporated into numerous New Era and spiritual david hoffmeister movements. Nevertheless, their influence is seen as a double-edged sword. On a single hand, it has presented a platform for individuals seeking spiritual growth and internal peace. On another hand, its teachings can donate to a tradition of spiritual skipping, wherever persons use spiritual ideas to avoid coping with personal and social issues. This could cause an application of escapism, where the focus on religious beliefs distracts from the prerequisite of engaging with and addressing real-world challenges.

Furthermore, the commercial accomplishment of ACIM and their connected components improves honest concerns. The expansion of workshops, publications, and seminars centered on ACIM can be seen as capitalizing on individuals' spiritual needs and vulnerabilities. Authorities disagree that the commercialization of spirituality may result in the exploitation of seekers, who might invest substantial time and income in to techniques that eventually don't produce on the promises. This commercialization can also donate to the dilution of the course's teachings, as different interpretations and changes proliferate, potentially resulting in confusion and misapplication of the principles.

Still another critical element to take into account may be the exclusivity and dogmatism that may occasionally accompany the ACIM community. As the class it self promotes common love and forgiveness, the way in which it's shown and used by some adherents may lead to an expression of spiritual elitism. This will create an "people versus them" thinking, wherever people who follow ACIM are regarded as enlightened, while those that don't are seen as misguided or unenlightened. Such attitudes could be divisive and counterproductive to the course's supposed targets of peace and unity. Experts argue that true spiritual development should foster inclusivity and humility, rather than developing a hierarchical difference between the spiritually awakened and the unawakened.
