The practical program of ACIM's teachings can be a spot of contention. Although some persons record positive transformations and personal development from following a course, the others find the practices to be useless or even harmful. The course's focus on forgiveness and enjoy is excellent, but authorities fight that it may be excessively simplified and naïve, declining to handle the difficulties of individual relationships and the need for boundaries and accountability. Furthermore, the course's length and rigorous nature can be overwhelming for some people, ultimately causing burnout or disillusionment. Critics suggest that the full time and energy needed to accomplish ACIM might be greater spent on more empirically reinforced healing practices or spiritual disciplines which have an established background of effectiveness.

The broader impact of ACIM on the spiritual and self-help towns is also worth considering. The class has inspired an important subsequent and has been integrated into numerous New Era and spiritual movements. Nevertheless, their influence is visible as a double-edged sword. On a single give, it's presented a structure for persons seeking spiritual development and inner acim davidc  peace. On another hand, their teachings may donate to a lifestyle of religious bypassing, where individuals use religious concepts to avoid coping with personal and cultural issues. This can result in an application of escapism, where the concentrate on religious values distracts from the prerequisite of engaging with and handling real-world challenges.

More over, the professional accomplishment of ACIM and its related products improves ethical concerns. The expansion of workshops, publications, and seminars centered on ACIM is seen as capitalizing on individuals' religious wants and vulnerabilities. Experts argue that the commercialization of spirituality may result in the exploitation of seekers, who may possibly invest substantial time and money into methods that ultimately do not offer on the promises. This commercialization may also contribute to the dilution of the course's teachings, as numerous interpretations and adaptations proliferate, perhaps resulting in confusion and misapplication of the principles.

Yet another important aspect to think about could be the exclusivity and dogmatism that may sometimes accompany the ACIM community. While the program it self promotes universal love and forgiveness, the way in which it is taught and used by some adherents can lead to a feeling of spiritual elitism. This could build an "people versus them" attitude, where people who follow ACIM are regarded as enlightened, while those that do not are considered as misguided or unenlightened. Such attitudes can be divisive and detrimental to the course's proposed objectives of peace and unity. Experts fight that true spiritual growth should foster inclusivity and humility, as opposed to creating a hierarchical difference between the spiritually awakened and the unawakened.
