The useful request of ACIM's teachings can also be a place of contention. While some individuals report positive transformations and particular growth from after the program, the others get the methods to be inadequate as well as harmful. The course's emphasis on forgiveness and love is remarkable, but authorities disagree that it can be excessively simplified and naïve, declining to deal with the complexities of individual associations and the requirement for boundaries and accountability. Also, the course's size and intense character can be overwhelming for some individuals, leading to burnout or disillusionment. Authorities declare that enough time and effort needed to accomplish ACIM might be greater used on more empirically reinforced healing practices or spiritual professions which have an established track record of effectiveness.

The broader impact of ACIM on the religious and self-help communities can be price considering. The program has inspired a significant following and has been integrated into numerous New Era and religious movements. But, its impact can be seen as a double-edged sword. On a single hand, it has provided a structure for individuals seeking spiritual growth and internal  a course in miracles  peace. On the other hand, their teachings can subscribe to a tradition of religious bypassing, where people use spiritual methods to avoid coping with personal and cultural issues. This may lead to a questionnaire of escapism, where in fact the give attention to religious ideals distracts from the prerequisite of interesting with and handling real-world challenges.

More over, the commercial success of ACIM and its related components increases ethical concerns. The growth of workshops, publications, and seminars centered on ACIM is seen as capitalizing on individuals' spiritual wants and vulnerabilities. Experts fight that the commercialization of spirituality can cause the exploitation of seekers, who may possibly invest substantial time and income into practices that eventually don't offer on their promises. This commercialization also can contribute to the dilution of the course's teachings, as different interpretations and changes proliferate, possibly leading to frustration and misapplication of the principles.

Yet another important part to take into account could be the exclusivity and dogmatism that will sometimes accompany the ACIM community. Whilst the course it self stimulates universal enjoy and forgiveness, the way in which it's taught and practiced by some adherents may result in a sense of spiritual elitism. This may produce an "people versus them" attitude, wherever people who follow ACIM are viewed as enlightened, while people who do not are considered as misguided or unenlightened. Such attitudes could be divisive and counterproductive to the course's proposed objectives of peace and unity. Experts argue that correct spiritual growth must foster inclusivity and humility, rather than developing a hierarchical variation involving the spiritually awakened and the unawakened.
