The practical request of ACIM's teachings can also be a point of contention. While some persons record good transformations and personal growth from following a program, the others get the methods to be inadequate as well as harmful. The course's increased exposure of forgiveness and enjoy is exceptional, but critics argue that it may be overly simplified and naïve, declining to address the difficulties of human associations and the requirement for boundaries and accountability. Moreover, the course's size and intense character could be frustrating for some people, ultimately causing burnout or disillusionment. Experts declare that the time and effort required to perform ACIM could possibly be better used on more empirically supported beneficial practices or religious disciplines that have an established history of effectiveness.

The broader affect of ACIM on the spiritual and self-help communities can be price considering. The class has influenced a substantial following and has been built-into numerous New Era and religious movements. But, its impact is visible as a double-edged sword. Using a course in miracles  one hand, it has offered a framework for individuals seeking religious growth and internal peace. On one other give, their teachings can subscribe to a culture of spiritual skipping, where individuals use spiritual concepts in order to avoid coping with particular and social issues. This may lead to a form of escapism, where the give attention to spiritual ideals distracts from the necessity of interesting with and addressing real-world challenges.

Furthermore, the industrial achievement of ACIM and their connected resources improves honest concerns. The proliferation of workshops, publications, and seminars predicated on ACIM is visible as capitalizing on individuals' religious wants and vulnerabilities. Experts argue that the commercialization of spirituality may lead to the exploitation of seekers, who might spend substantial time and money into techniques that ultimately do not produce on the promises. This commercialization may also subscribe to the dilution of the course's teachings, as different understandings and changes proliferate, possibly resulting in confusion and misapplication of the principles.

Yet another critical part to consider could be the exclusivity and dogmatism that can often accompany the ACIM community. Whilst the course itself stimulates universal love and forgiveness, the way it's taught and practiced by some adherents can cause a feeling of spiritual elitism. This will build an "us versus them" mentality, where those who follow ACIM are viewed as enlightened, while people who don't are viewed as misguided or unenlightened. Such attitudes could be divisive and detrimental to the course's proposed objectives of peace and unity. Authorities fight that correct religious development must foster inclusivity and humility, rather than developing a hierarchical difference between the spiritually awakened and the unawakened.
