The realistic software of ACIM's teachings is also a point of contention. Although some individuals record positive transformations and particular growth from following course, the others discover the methods to be inadequate as well as harmful. The course's increased exposure of forgiveness and enjoy is excellent, but experts argue that it could be excessively basic and naïve, declining to handle the difficulties of human relationships and the need for limits and accountability. Moreover, the course's size and intensive character can be overwhelming for some individuals, ultimately causing burnout or disillusionment. Authorities declare that enough time and effort expected to accomplish ACIM could possibly be greater allocated to more empirically supported beneficial practices or spiritual professions which have a proven history of effectiveness.

The broader influence of ACIM on the religious and self-help towns is also value considering. The program has inspired a significant following and has been incorporated into various New Era and religious movements. Nevertheless, their effect is seen as a double-edged sword. Using one hand, it has offered a platform for individuals seeking spiritual development and internal peace. On a course in miracles the other hand, its teachings may contribute to a tradition of religious bypassing, where individuals use religious concepts in order to avoid working with personal and cultural issues. This could lead to an application of escapism, where in actuality the focus on religious values distracts from the requisite of participating with and handling real-world challenges.

Furthermore, the industrial success of ACIM and their connected materials increases ethical concerns. The growth of workshops, books, and seminars predicated on ACIM is visible as capitalizing on individuals' religious needs and vulnerabilities. Critics fight that the commercialization of spirituality can result in the exploitation of seekers, who might invest significant time and money in to practices that eventually don't deliver on the promises. This commercialization may also subscribe to the dilution of the course's teachings, as various interpretations and adaptations proliferate, perhaps resulting in frustration and misapplication of the principles.

Still another important part to take into account is the exclusivity and dogmatism that will often accompany the ACIM community. While the program itself stimulates universal enjoy and forgiveness, the way in which it's taught and practiced by some adherents can result in an expression of spiritual elitism. This may create an "people versus them" mentality, where people who follow ACIM are regarded as enlightened, while people who 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 argue that correct spiritual growth must foster inclusivity and humility, rather than creating a hierarchical variation involving the spiritually awakened and the unawakened.
