The useful request of ACIM's teachings can also be a point of contention. While some individuals record good transformations and particular development from after the course, others discover the practices to be useless as well as harmful. The course's increased exposure of forgiveness and love is remarkable, but critics argue that it could be very simplified and naïve, declining to address the difficulties of individual relationships and the requirement for boundaries and accountability. Additionally, the course's size and rigorous character could be overwhelming for some people, leading to burnout or disillusionment. Authorities claim that the full time and effort needed to complete ACIM might be greater allocated to more empirically reinforced therapeutic techniques or spiritual professions which have an established history of effectiveness.

The broader affect of ACIM on the religious and self-help communities is also value considering. The program has inspired a significant subsequent and has been built-into different New Era and spiritual movements. However, their influence can be seen as a double-edged sword. Using one give, it has offered a structure for individuals a course in miracles seeking religious growth and internal peace. On the other give, its teachings may donate to a lifestyle of spiritual skipping, where individuals use spiritual methods to avoid coping with personal and cultural issues. This could result in a form of escapism, where in actuality the concentrate on spiritual ideals distracts from the necessity of engaging with and approaching real-world challenges.

More over, the industrial accomplishment of ACIM and its related products increases moral concerns. The proliferation of workshops, publications, and seminars based on ACIM can be seen as capitalizing on individuals' religious wants and vulnerabilities. Critics fight that the commercialization of spirituality may cause the exploitation of seekers, who may possibly spend significant time and income in to practices that eventually do not offer on their promises. This commercialization also can donate to the dilution of the course's teachings, as various interpretations and changes proliferate, possibly ultimately causing frustration and misapplication of the principles.

Yet another important part to take into account may be the exclusivity and dogmatism that will sometimes accompany the ACIM community. Whilst the program it self encourages general enjoy and forgiveness, the way in which it is shown and used by some adherents may cause a sense of spiritual elitism. This will build an "people versus them" mindset, where those that follow ACIM are regarded as enlightened, while those that don't are considered as misguided or unenlightened. Such attitudes can be divisive and counterproductive to the course's purported objectives of peace and unity. Authorities disagree that true spiritual development must foster inclusivity and humility, as opposed to creating a hierarchical variance involving the spiritually awakened and the unawakened.
