The useful software of ACIM's teachings is also a place of contention. Although some persons report good transformations and personal growth from following the class, the others get the practices to be ineffective or even harmful. The course's focus on forgiveness and love is admirable, but critics argue that it may be very simplistic and naïve, failing to deal with the complexities of individual relationships and the requirement for limits and accountability. Also, the course's length and intense character may be frustrating for some individuals, leading to burnout or disillusionment. Experts claim that enough time and energy expected to complete ACIM could possibly be better spent on more empirically reinforced healing techniques or spiritual disciplines that have a proven track record of effectiveness.

The broader impact of ACIM on the spiritual and self-help towns can also be price considering. The course has encouraged a significant following and has been incorporated into numerous New Era and religious movements. Nevertheless, their effect is seen as a double-edged sword. Using one give, it's provided a structure for individuals david hoffmeister  seeking spiritual development and internal peace. On another hand, its teachings can subscribe to a culture of spiritual bypassing, where people use spiritual concepts in order to avoid dealing with personal and social issues. This can cause an application of escapism, where in actuality the focus on religious attitudes distracts from the necessity of participating with and handling real-world challenges.

Furthermore, the commercial success of ACIM and their related resources raises ethical concerns. The growth of workshops, publications, and seminars based on ACIM is seen as capitalizing on individuals' religious wants and vulnerabilities. Experts disagree that the commercialization of spirituality may cause the exploitation of seekers, who may spend significant time and income in to techniques that ultimately do not deliver on the promises. This commercialization can also subscribe to the dilution of the course's teachings, as various understandings and adaptations proliferate, perhaps leading to confusion and misapplication of the principles.

Another important aspect to consider could be the exclusivity and dogmatism that could often accompany the ACIM community. As the program it self promotes general love and forgiveness, the way it's shown and practiced by some adherents can cause a sense of spiritual elitism. This may create an "people versus them" mindset, wherever people who follow ACIM are regarded as enlightened, while those who do not are viewed as misguided or unenlightened. Such attitudes could be divisive and counterproductive to the course's supposed goals of peace and unity. Critics argue that true religious development must foster inclusivity and humility, rather than creating a hierarchical distinction between the spiritually awakened and the unawakened.
