The useful application of ACIM's teachings is also a spot of contention. Although some persons record good transformations and particular development from after the program, others find the practices to be useless as well as harmful. The course's focus on forgiveness and enjoy is excellent, but authorities argue that it can be overly easy and naïve, failing to deal with the complexities of individual relationships and the requirement for limits and accountability. Furthermore, the course's length and intense nature may be overwhelming for some individuals, resulting in burnout or disillusionment. Critics claim that enough time and effort needed to accomplish ACIM might be greater allocated to more empirically supported healing methods or religious disciplines which have a proven history of effectiveness.

The broader affect of ACIM on the spiritual and self-help neighborhoods can be price considering. The class has encouraged a substantial following and has been built-into numerous New Age and religious movements. However, its impact is visible as a double-edged sword. Using one acim give, it has presented a structure for people seeking religious development and inner peace. On one other hand, their teachings can donate to a tradition of spiritual bypassing, where persons use religious concepts to avoid coping with particular and cultural issues. This will result in a form of escapism, where the give attention to religious values distracts from the prerequisite of interesting with and addressing real-world challenges.

Moreover, the professional accomplishment of ACIM and its connected components raises moral concerns. The growth of workshops, books, and seminars centered on ACIM is seen as capitalizing on individuals' religious wants and vulnerabilities. Authorities disagree that the commercialization of spirituality can cause the exploitation of seekers, who may possibly spend substantial time and income in to techniques that eventually don't produce on their promises. That commercialization may also donate to the dilution of the course's teachings, as various understandings and changes proliferate, perhaps resulting in distress and misapplication of the principles.

Yet another important element to take into account may be the exclusivity and dogmatism that could often accompany the ACIM community. As the class it self advances common enjoy and forgiveness, the way it's taught and used by some adherents may result in a feeling of spiritual elitism. This could create an "us versus them" mentality, where those that follow ACIM are viewed as enlightened, while people who do not are viewed as misguided or unenlightened. Such attitudes may be divisive and detrimental to the course's proposed objectives of peace and unity. Critics fight that true religious growth should foster inclusivity and humility, rather than creating a hierarchical variance between the spiritually awakened and the unawakened.

The problem of whether ACIM is "true" eventually depends on one's requirements for truth. From the medical perception, having less scientific evidence supporting the statements of divine dictation and the course's metaphysical assertions could be reasons for skepticism. From a philosophical standpoint, the interior inconsistencies and syncretism of ACIM may lead to issues about its coherence and sensible validity. From the psychological perspective, the prospect of cognitive dissonance and emotional hardship increases concerns concerning the course's impact on intellectual health. And from a practical perspective, the blended results noted by practitioners and the potential for commercialization and exploitation suggest that ACIM's usefulness and moral ranking are questionable.
