The useful request of ACIM's teachings can be a place of contention. Though some individuals report good transformations and particular development from following the program, the others find the techniques to be ineffective or even harmful. The course's focus on forgiveness and enjoy is remarkable, but authorities disagree that it can be very simplistic and naïve, declining to address the complexities of individual associations and the necessity for boundaries and accountability. Additionally, the course's length and extensive nature could be overwhelming for some people, leading to burnout or disillusionment. Experts suggest that the time and effort expected to complete ACIM could be better spent on more empirically reinforced therapeutic practices or spiritual disciplines which have a proven background of effectiveness.

The broader influence of ACIM on the religious and self-help areas can be price considering. The course has encouraged a substantial following and has been integrated into numerous New Age and spiritual movements. Nevertheless, their influence is seen as a double-edged sword. On a single give, it has presented a construction for people seeking religious growth and internal acim  peace. On the other hand, their teachings may contribute to a lifestyle of spiritual skipping, where individuals use spiritual ideas to avoid dealing with particular and social issues. This will lead to a form of escapism, where in fact the concentrate on spiritual attitudes distracts from the necessity of interesting with and approaching real-world challenges.

Furthermore, the professional success of ACIM and their related resources increases ethical concerns. The proliferation of workshops, books, and seminars predicated on ACIM is seen as capitalizing on individuals' religious needs and vulnerabilities. Experts argue that the commercialization of spirituality can cause the exploitation of seekers, who may invest significant time and income in to techniques that eventually don't supply on their promises. That commercialization may also contribute to the dilution of the course's teachings, as various interpretations and adaptations proliferate, perhaps ultimately causing confusion and misapplication of the principles.

Yet another critical part to think about is the exclusivity and dogmatism that could occasionally accompany the ACIM community. Whilst the course itself promotes universal enjoy and forgiveness, the way in which it is taught and used by some adherents can lead to an expression of religious elitism. This may produce an "us versus them" mindset, wherever 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 counterproductive to the course's purported objectives of peace and unity. Experts fight that correct religious growth must foster inclusivity and humility, rather than developing a hierarchical distinction involving the spiritually awakened and the unawakened.
