The useful application of ACIM's teachings can also be a point of contention. While some people report good transformations and particular growth from after the class, the others find the methods to be useless or even harmful. The course's focus on forgiveness and love is admirable, but experts fight that it may be very basic and naïve, declining to deal with the difficulties of individual relationships and the requirement for boundaries and accountability. Also, the course's period and rigorous character can be frustrating for many people, ultimately causing burnout or disillusionment. Experts declare that the full time and energy required to accomplish ACIM could be better used on more empirically reinforced beneficial methods or religious disciplines which have an established history of effectiveness.

The broader impact of ACIM on the religious and self-help areas can also be value considering. The program has encouraged a significant subsequent and has been integrated into different New Age and spiritual movements. But, its impact is visible as a a course in miracles  double-edged sword. On one hand, it's offered a platform for individuals seeking spiritual growth and inner peace. On the other give, its teachings can contribute to a tradition of religious bypassing, where persons use spiritual ideas to avoid coping with particular and social issues. This may cause an application of escapism, where in fact the focus on spiritual values distracts from the requisite of participating with and handling real-world challenges.

Furthermore, the industrial accomplishment of ACIM and its connected materials increases moral concerns. The growth of workshops, publications, and seminars predicated on ACIM is seen as capitalizing on individuals' religious needs and vulnerabilities. Critics argue that the commercialization of spirituality may lead to the exploitation of seekers, who may spend substantial time and money in to techniques that finally don't offer on their promises. This commercialization also can donate to the dilution of the course's teachings, as different understandings and changes proliferate, possibly resulting in frustration and misapplication of the principles.

Still another important part to consider may be the exclusivity and dogmatism that may often accompany the ACIM community. Whilst the course itself advances common enjoy and forgiveness, the way it's taught and used by some adherents can cause a sense of spiritual elitism. This could create an "people versus them" thinking, wherever people who follow ACIM are seen as enlightened, while those that don't are viewed as misguided or unenlightened. Such attitudes can be divisive and counterproductive to the course's supposed targets of peace and unity. Critics argue that correct religious development must foster inclusivity and humility, as opposed to making a hierarchical variation between the spiritually awakened and the unawakened.
