The realistic application of ACIM's teachings can also be a place of contention. While some individuals report good transformations and particular development from following a course, the others get the techniques to be inadequate as well as harmful. The course's increased exposure of forgiveness and enjoy is excellent, but authorities disagree that it can be overly simplistic and naïve, declining to deal with the difficulties of human associations and the requirement for boundaries and accountability. Moreover, the course's period and extensive character may be overwhelming for some individuals, ultimately causing burnout or disillusionment. Critics claim that enough time and effort expected to perform ACIM could possibly be better allocated to more empirically supported healing techniques or spiritual disciplines which have a proven track record of effectiveness.

The broader impact of ACIM on the spiritual and self-help towns can be value considering. The program has encouraged a significant subsequent and has been integrated into numerous New Age and religious movements. Nevertheless, its influence is seen as a double-edged sword. On one hand, it's offered a construction for acim individuals seeking religious development and internal peace. On one other give, their teachings can donate to a tradition of religious skipping, wherever individuals use religious ideas to avoid dealing with personal and social issues. This will lead to a form of escapism, where in actuality the concentrate on religious values distracts from the requisite of engaging with and handling real-world challenges.

Moreover, the commercial accomplishment of ACIM and its related resources increases ethical concerns. The expansion of workshops, publications, and seminars based on ACIM can be seen as capitalizing on individuals' spiritual needs and vulnerabilities. Experts fight that the commercialization of spirituality may lead to the exploitation of seekers, who might invest significant time and income in to practices that finally do not provide on the promises. This commercialization may also contribute to the dilution of the course's teachings, as numerous interpretations and adaptations proliferate, perhaps resulting in confusion and misapplication of the principles.

Yet another critical element to think about may be the exclusivity and dogmatism that could occasionally accompany the ACIM community. Whilst the class itself advances general enjoy and forgiveness, the way in which it is taught and used by some adherents can result in an expression of religious elitism. This can build an "people versus them" attitude, where those that follow ACIM are seen as enlightened, while those who don't are viewed as misguided or unenlightened. Such attitudes can be divisive and detrimental to the course's proposed goals of peace and unity. Authorities argue that true spiritual development should foster inclusivity and humility, as opposed to creating a hierarchical variance involving the spiritually awakened and the unawakened.
