The practical request of ACIM's teachings can also be a point of contention. Although some people report good transformations and particular development from following the class, the others find the practices to be ineffective as well as harmful. The course's increased exposure of forgiveness and love is exceptional, but authorities disagree that it can be very simplistic and naïve, declining to address the complexities of individual relationships and the need for limits and accountability. Furthermore, the course's length and intense nature may be overwhelming for some people, leading to burnout or disillusionment. Critics suggest that the full time and energy required to complete ACIM could possibly be better allocated to more empirically reinforced healing techniques or spiritual disciplines which have a proven background of effectiveness.

The broader affect of ACIM on the spiritual and self-help towns is also price considering. The course has inspired a significant subsequent and has been built-into various New Age and spiritual movements. But, their impact is visible as a double-edged sword. Using one hand, it has offered a acim construction for people seeking spiritual growth and inner peace. On one other hand, its teachings can contribute to a culture of religious bypassing, where persons use spiritual methods in order to avoid working with personal and cultural issues. This will result in a questionnaire of escapism, where in actuality the concentrate on spiritual values distracts from the prerequisite of interesting with and approaching real-world challenges.

More over, the industrial achievement of ACIM and their connected products improves honest concerns. The growth of workshops, publications, and seminars predicated on ACIM can be seen as capitalizing on individuals' spiritual wants and vulnerabilities. Authorities argue that the commercialization of spirituality may lead to the exploitation of seekers, who may possibly invest significant time and money in to practices that eventually do not supply on the promises. That commercialization can also contribute to the dilution of the course's teachings, as numerous interpretations and adaptations proliferate, probably resulting in frustration and misapplication of the principles.

Yet another critical part to think about is the exclusivity and dogmatism that can often accompany the ACIM community. While the program it self stimulates universal love and forgiveness, the way in which it's taught and used by some adherents can result in a sense of religious elitism. This could build an "people versus them" attitude, wherever people who follow ACIM are regarded as enlightened, while those who don't are seen as misguided or unenlightened. Such attitudes may be divisive and detrimental to the course's purported goals of peace and unity. Critics disagree that true religious development must foster inclusivity and humility, as opposed to making a hierarchical variance between the spiritually awakened and the unawakened.
