The practical application of ACIM's teachings can be a spot of contention. Although some people record good transformations and personal growth from following a class, the others find the techniques to be inadequate or even harmful. The course's emphasis on forgiveness and enjoy is remarkable, but authorities fight that it can be very easy and naïve, declining to handle the complexities of individual relationships and the need for limits and accountability. Also, the course's period and intensive nature could be frustrating for many people, leading to burnout or disillusionment. Critics suggest that enough time and effort required to complete ACIM might be better allocated to more empirically reinforced therapeutic techniques or spiritual professions that have a proven history of effectiveness.

The broader affect of ACIM on the religious and self-help areas can be worth considering. The program has inspired a substantial following and has been built-into different New Age and spiritual movements. However, its effect can be seen as a double-edged sword. On acim videos one hand, it's presented a structure for people seeking religious development and inner peace. On one other give, their teachings can contribute to a lifestyle of religious bypassing, where people use religious ideas in order to avoid coping with personal and social issues. This could lead to an application of escapism, where in fact the give attention to religious ideals distracts from the requisite of engaging with and handling real-world challenges.

Moreover, the commercial accomplishment of ACIM and its related materials increases ethical concerns. The proliferation of workshops, publications, and seminars centered on ACIM is seen as capitalizing on individuals' religious wants and vulnerabilities. Critics argue that the commercialization of spirituality may cause the exploitation of seekers, who may spend significant time and income in to techniques that ultimately do not supply on their promises. That commercialization also can donate to the dilution of the course's teachings, as various understandings and changes proliferate, perhaps leading to frustration and misapplication of the principles.

Yet another critical element to take into account may be the exclusivity and dogmatism that could sometimes accompany the ACIM community. While the class itself stimulates common enjoy and forgiveness, the way in which it is shown and practiced by some adherents may lead to a sense of religious elitism. This may build an "people versus them" mentality, where those who follow ACIM are viewed as enlightened, while people who do not are seen as misguided or unenlightened. Such attitudes can be divisive and detrimental to the course's purported objectives of peace and unity. Critics argue that true spiritual growth should foster inclusivity and humility, rather than making a hierarchical variation involving the spiritually awakened and the unawakened.
