The practical program of ACIM's teachings is also a point of contention. While some individuals record positive transformations and particular development from after the program, the others get the practices to be useless as well as harmful. The course's emphasis on forgiveness and love is excellent, but experts argue that it may be very simplistic and naïve, declining to deal with the difficulties of human associations and the requirement for boundaries and accountability. Moreover, the course's size and extensive nature can be frustrating for many people, leading to burnout or disillusionment. Authorities claim that the full time and effort required to complete ACIM might be better spent on more empirically reinforced therapeutic techniques or spiritual disciplines which have a proven history of effectiveness.

The broader affect of ACIM on the spiritual and self-help neighborhoods can be price considering. The class has inspired an important following and has been built-into numerous New Age and spiritual movements. However, their effect is seen as a double-edged sword. On a the christ
single hand, it has offered a structure for individuals seeking spiritual growth and internal peace. On another give, their teachings may subscribe to a culture of religious bypassing, where individuals use spiritual concepts in order to avoid working with personal and cultural issues. This can cause an application of escapism, where the give attention to religious attitudes distracts from the necessity of engaging with and addressing real-world challenges.

Moreover, the professional achievement of ACIM and its related products increases ethical concerns. The growth of workshops, publications, and seminars centered on ACIM is visible as capitalizing on individuals' spiritual wants and vulnerabilities. Authorities argue that the commercialization of spirituality may result in the exploitation of seekers, who might spend significant time and money into methods that eventually do not produce on the promises. This commercialization may also contribute to the dilution of the course's teachings, as numerous interpretations and changes proliferate, possibly leading to distress and misapplication of the principles.

Another critical part to think about may be the exclusivity and dogmatism that will occasionally accompany the ACIM community. While the course itself stimulates universal love and forgiveness, just how it's shown and used by some adherents can result in an expression of spiritual elitism. This may create an "people versus them" thinking, wherever those that follow ACIM are viewed as enlightened, while those that do not are viewed as misguided or unenlightened. Such attitudes may be divisive and counterproductive to the course's purported targets of peace and unity. Critics argue that correct spiritual growth must foster inclusivity and humility, rather than making a hierarchical difference involving the spiritually awakened and the unawakened.
