The practical software of ACIM's teachings is also a point of contention. Although some persons report good transformations and particular growth from following program, the others get the methods to be inadequate or even harmful. The course's increased exposure of forgiveness and enjoy is admirable, but authorities argue that it can be very basic and naïve, failing to deal with the complexities of individual associations and the necessity for limits and accountability. Also, the course's size and extensive character may be frustrating for a lot of people, ultimately causing burnout or disillusionment. Experts declare that enough time and energy required to complete ACIM might be better used on more empirically reinforced therapeutic methods or spiritual disciplines which have an established background of effectiveness.

The broader affect of ACIM on the religious and self-help areas can be worth considering. The course has inspired a substantial following and has been integrated into different New Age and spiritual movements. But, their effect can be seen as a double-edged sword. On one give, it's offered a structure for individuals seeking religious development and inner peace. On another give, their teachings can donate to a tradition of religious skipping, wherever people use spiritual methods to avoid working with personal and social issues. This could cause an application of escapism, where in fact the concentrate on religious values distracts from the prerequisite of engaging with and approaching real-world challenges.

Furthermore, the industrial accomplishment of ACIM and their connected resources increases honest concerns. The proliferation of workshops, books, and seminars centered on ACIM is seen as capitalizing on individuals' spiritual wants and vulnerabilities. Critics disagree  acim that the commercialization of spirituality can result in the exploitation of seekers, who may spend significant time and income into practices that fundamentally do not supply on the promises. This commercialization may also donate to the dilution of the course's teachings, as numerous understandings and adaptations proliferate, probably leading to distress and misapplication of the principles.

Yet another important element to take into account is the exclusivity and dogmatism that may occasionally accompany the ACIM community. Whilst the program it self promotes universal love and forgiveness, just how it is shown and used by some adherents may cause a sense of spiritual elitism. This can develop an "us versus them" thinking, where those that follow ACIM are regarded as enlightened, while those that don't are considered as misguided or unenlightened. Such attitudes can be divisive and counterproductive to the course's proposed objectives of peace and unity. Authorities fight that correct religious growth should foster inclusivity and humility, as opposed to creating a hierarchical variation between the spiritually awakened and the unawakened.
