The practical application of ACIM's teachings can also be a spot of contention. Although some people report good transformations and personal development from following a program, the others get the methods to be ineffective as well as harmful. The course's emphasis on forgiveness and enjoy is exceptional, but authorities disagree that it can be very simplified and naïve, failing to handle the difficulties of human relationships and the need for limits and accountability. Additionally, the course's length and intense nature can be overwhelming for some people, leading to burnout or disillusionment. Critics claim that the time and work needed to complete ACIM could be better used on more empirically reinforced beneficial practices or religious disciplines that have a proven background of effectiveness.

The broader impact of ACIM on the spiritual and self-help neighborhoods can also be value considering. The program has inspired an important subsequent and has been incorporated into numerous New Era and spiritual movements. Nevertheless, its impact is david hoffmeister  visible as a double-edged sword. Using one hand, it has provided a platform for people seeking religious growth and inner peace. On another hand, its teachings can contribute to a tradition of spiritual skipping, wherever people use spiritual ideas to prevent working with particular and social issues. This will lead to a questionnaire of escapism, where the give attention to spiritual ideals distracts from the prerequisite of engaging with and approaching real-world challenges.

Moreover, the industrial accomplishment of ACIM and its connected products increases ethical concerns. The growth of workshops, publications, and seminars centered on ACIM is visible as capitalizing on individuals' religious wants and vulnerabilities. Authorities disagree that the commercialization of spirituality may cause the exploitation of seekers, who might invest substantial time and money in to techniques that fundamentally do not supply on the promises. That commercialization can also donate to the dilution of the course's teachings, as various understandings and adaptations proliferate, probably ultimately causing distress and misapplication of the principles.

Still another critical part to think about could be the exclusivity and dogmatism that can often accompany the ACIM community. While the course itself promotes common love and forgiveness, the way it is taught and used by some adherents may lead to an expression of spiritual elitism. This may develop an "people versus them" thinking, wherever people who follow ACIM are seen as enlightened, while those that don't are seen as misguided or unenlightened. Such attitudes may be divisive and detrimental to the course's supposed objectives of peace and unity. Experts fight that true religious growth should foster inclusivity and humility, rather than developing a hierarchical distinction involving the spiritually awakened and the unawakened.
