The useful program of ACIM's teachings can also be a point of contention. Although some individuals report good transformations and personal development from following program, others find the techniques to be inadequate as well as harmful. The course's emphasis on forgiveness and love is remarkable, but experts fight that it can be overly easy and naïve, failing to address the difficulties of human associations and the requirement for limits and accountability. Moreover, the course's size and extensive nature can be frustrating for some individuals, ultimately causing burnout or disillusionment. Experts suggest that the full time and effort expected to perform ACIM could be better allocated to more empirically supported therapeutic practices or religious professions which have a proven background of effectiveness.

The broader impact of ACIM on the religious and self-help communities can be value considering. The program has encouraged an important following and has been built-into different New Era and religious movements. But, their impact can be seen as a double-edged sword. On one david acim give, it has presented a framework for people seeking spiritual development and inner peace. On the other give, its teachings can contribute to a tradition of religious bypassing, wherever persons use religious concepts to prevent dealing with particular and social issues. This could cause a questionnaire of escapism, where in actuality the give attention to religious values distracts from the necessity of engaging with and handling real-world challenges.

More over, the commercial accomplishment of ACIM and its related components increases honest concerns. The proliferation of workshops, books, and seminars centered on ACIM can be seen as capitalizing on individuals' spiritual needs and vulnerabilities. Critics disagree that the commercialization of spirituality may lead to the exploitation of seekers, who may invest substantial time and money in to methods that fundamentally do not produce on their promises. That commercialization also can contribute to the dilution of the course's teachings, as numerous interpretations and adaptations proliferate, potentially resulting in distress and misapplication of the principles.

Yet another important aspect to consider may be the exclusivity and dogmatism that can sometimes accompany the ACIM community. While the program itself encourages universal enjoy and forgiveness, the way in which it's shown and used by some adherents can cause a feeling of religious elitism. This may produce an "people versus them" attitude, wherever people who follow ACIM are regarded as enlightened, while those who do not are seen as misguided or unenlightened. Such attitudes could be divisive and counterproductive to the course's supposed targets of peace and unity. Experts disagree that true religious development should foster inclusivity and humility, as opposed to developing a hierarchical distinction involving the spiritually awakened and the unawakened.
