The sensible software of ACIM's teachings can also be a place of contention. Though some persons report good transformations and particular development from following the class, the others discover the techniques to be inadequate as well as harmful. The course's increased exposure of forgiveness and enjoy is admirable, but authorities disagree that it may be excessively simplified and naïve, failing to handle the difficulties of human associations and the need for boundaries and accountability. Moreover, the course's size and extensive character could be frustrating for some individuals, leading to burnout or disillusionment. Experts declare that enough time and energy expected to complete ACIM could possibly be greater used on more empirically reinforced therapeutic methods or religious disciplines that have a proven history of effectiveness.

The broader impact of ACIM on the spiritual and self-help communities can be value considering. The class has encouraged a substantial subsequent and has been integrated into various New Era and spiritual movements. Nevertheless, their influence is seen as a double-edged sword. On a single hand, it's provided a framework for the christ persons seeking religious growth and inner peace. On one other hand, their teachings can contribute to a culture of spiritual skipping, where people use spiritual ideas to prevent working with personal and social issues. This may cause an application of escapism, where in fact the give attention to spiritual attitudes distracts from the requisite of interesting with and addressing real-world challenges.

More over, the industrial achievement of ACIM and its connected products increases honest concerns. The growth of workshops, books, and seminars based on ACIM is seen as capitalizing on individuals' spiritual wants and vulnerabilities. Experts argue that the commercialization of spirituality can cause the exploitation of seekers, who may possibly invest significant time and money into methods that eventually do not deliver on the promises. That commercialization also can contribute to the dilution of the course's teachings, as different understandings and changes proliferate, possibly leading to frustration and misapplication of the principles.

Another critical part to think about is the exclusivity and dogmatism that could often accompany the ACIM community. While the course itself advances common love and forgiveness, the way it's taught and practiced by some adherents may lead to an expression of spiritual elitism. This can build an "people versus them" attitude, where people who follow ACIM are viewed as enlightened, while those that do not are viewed as misguided or unenlightened. Such attitudes could be divisive and counterproductive to the course's proposed objectives of peace and unity. Authorities disagree that true spiritual development should foster inclusivity and humility, as opposed to developing a hierarchical distinction involving the spiritually awakened and the unawakened.
