The sensible application of ACIM's teachings can be a place of contention. Though some individuals report good transformations and personal growth from after the course, others discover the practices to be inadequate as well as harmful. The course's increased exposure of forgiveness and enjoy is excellent, but authorities argue that it could be very simplistic and naïve, failing to address the difficulties of human associations and the necessity for boundaries and accountability. Additionally, the course's length and rigorous character can be frustrating for many people, resulting in burnout or disillusionment. Critics claim that the time and energy required to accomplish ACIM could possibly be better allocated to more empirically supported beneficial techniques or spiritual disciplines which have an established history of effectiveness.

The broader affect of ACIM on the spiritual and self-help communities can be value considering. The class has influenced a significant subsequent and has been incorporated into various New Era and spiritual a course in miracles movements. However, their effect can be seen as a double-edged sword. On one give, it has offered a platform for persons seeking religious growth and internal peace. On the other hand, their teachings can donate to a lifestyle of religious skipping, where persons use spiritual concepts in order to avoid coping with personal and social issues. This can cause an application of escapism, where in fact the concentrate on religious beliefs distracts from the requisite of engaging with and approaching real-world challenges.

Moreover, the commercial success of ACIM and its related materials increases moral concerns. The growth of workshops, books, and seminars predicated on ACIM is seen as capitalizing on individuals' spiritual needs and vulnerabilities. Authorities disagree that the commercialization of spirituality can cause the exploitation of seekers, who may possibly spend significant time and income into methods that eventually do not supply on their promises. This commercialization can also subscribe to the dilution of the course's teachings, as different interpretations and adaptations proliferate, probably resulting in frustration and misapplication of the principles.

Another critical element to think about is the exclusivity and dogmatism that could occasionally accompany the ACIM community. While the course itself promotes general love and forgiveness, the way it's shown and practiced by some adherents can result in an expression of spiritual elitism. This may produce an "people versus them" mindset, where those who follow ACIM are seen as enlightened, while those who do not are viewed as misguided or unenlightened. Such attitudes can be divisive and detrimental to the course's proposed targets of peace and unity. Critics fight that correct religious growth must foster inclusivity and humility, as opposed to making a hierarchical variance involving the spiritually awakened and the unawakened.
