The realistic program of ACIM's teachings is also a point of contention. Although some persons record good transformations and personal growth from after the class, the others discover the practices to be inadequate as well as harmful. The course's increased exposure of forgiveness and love is exceptional, but critics fight that it may be overly simplistic and naïve, declining to deal with the complexities of individual relationships and the requirement for boundaries and accountability. Additionally, the course's period and rigorous nature may be frustrating for a lot of people, resulting in burnout or disillusionment. Authorities suggest that the time and effort needed to perform ACIM could be better spent on more empirically reinforced therapeutic practices or religious disciplines that have an established track record of effectiveness.

The broader influence of ACIM on the religious and self-help towns is also worth considering. The program has inspired an important following and has been incorporated into various New Era and religious movements. Nevertheless, its impact can be seen as a double-edged sword. On one hand, it has offered a framework for un curso de milagros seeking spiritual development and inner peace. On another hand, its teachings may subscribe to a culture of spiritual skipping, wherever persons use religious concepts to prevent dealing with personal and cultural issues. This can result in an application of escapism, where in fact the give attention to spiritual values distracts from the prerequisite of engaging with and approaching real-world challenges.

More over, the industrial accomplishment of ACIM and its related products raises moral concerns. The expansion of workshops, publications, and seminars based on ACIM is visible as capitalizing on individuals' religious wants and vulnerabilities. Experts fight that the commercialization of spirituality can cause the exploitation of seekers, who may invest significant time and money into methods that finally do not offer on their promises. This commercialization also can donate to the dilution of the course's teachings, as numerous understandings and changes proliferate, perhaps ultimately causing distress and misapplication of the principles.

Still another important part to consider is the exclusivity and dogmatism that will occasionally accompany the ACIM community. Whilst the course it self advances universal enjoy and forgiveness, the way in which it is shown and used by some adherents may cause a sense of religious elitism. This may develop an "us versus them" thinking, where those who follow ACIM are regarded as enlightened, while those who don't are viewed as misguided or unenlightened. Such attitudes can be divisive and detrimental to the course's purported objectives of peace and unity. Critics argue that correct spiritual growth should foster inclusivity and humility, as opposed to creating a hierarchical distinction between the spiritually awakened and the unawakened.
