The useful software of ACIM's teachings can be a spot of contention. Although some people record positive transformations and particular growth from following the class, others get the techniques to be inadequate or even harmful. The course's increased exposure of forgiveness and love is remarkable, but authorities argue that it may be very simplistic and naïve, failing to address the difficulties of individual associations and the requirement for boundaries and accountability. Furthermore, the course's period and intense character could be frustrating for many people, resulting in burnout or disillusionment. Critics suggest that enough time and energy needed to perform ACIM could possibly be better spent on more empirically supported beneficial practices or spiritual professions that have an established history of effectiveness.

The broader affect of ACIM on the religious and self-help communities is also value considering. The program has encouraged a significant subsequent and has been built-into different New Age and spiritual movements. However, their impact is visible as a double-edged sword. On one give, it has provided a construction for individuals seeking spiritual growth and inner non dual teachers  peace. On the other give, their teachings may contribute to a lifestyle of spiritual skipping, where persons use religious methods to avoid working with particular and social issues. This can lead to an application of escapism, where the give attention to religious ideals distracts from the requisite of interesting with and approaching real-world challenges.

Furthermore, the commercial accomplishment of ACIM and their related products improves ethical concerns. The growth of workshops, books, and seminars centered on ACIM can be seen as capitalizing on individuals' religious wants and vulnerabilities. Critics argue that the commercialization of spirituality can lead to the exploitation of seekers, who might spend substantial time and money into practices that ultimately don't produce on the promises. That commercialization can also donate to the dilution of the course's teachings, as different understandings and changes proliferate, perhaps leading to confusion and misapplication of the principles.

Another critical element to take into account is the exclusivity and dogmatism that may occasionally accompany the ACIM community. As the class it self encourages general enjoy and forgiveness, the way in which it's taught and practiced by some adherents may result in a sense of spiritual elitism. This may build an "people versus them" mentality, where people who follow ACIM are viewed as enlightened, while those who don't are considered as misguided or unenlightened. Such attitudes can be divisive and counterproductive to the course's proposed targets of peace and unity. Critics fight that correct spiritual growth must foster inclusivity and humility, as opposed to making a hierarchical variance between the spiritually awakened and the unawakened.
