The sensible application of ACIM's teachings can also be a spot of contention. While some individuals record positive transformations and personal development from following a class, others find the methods to be useless or even harmful. The course's emphasis on forgiveness and enjoy is remarkable, but critics fight that it can be overly basic and naïve, failing to address the complexities of individual associations and the requirement for boundaries and accountability. Additionally, the course's period and extensive nature may be overwhelming for some people, leading to burnout or disillusionment. Critics declare that the time and energy needed to complete ACIM could possibly be better used on more empirically reinforced beneficial methods or spiritual professions which have an established history of effectiveness.

The broader influence of ACIM on the religious and self-help areas can be value considering. The course has influenced an important following and has been integrated into numerous New Age and spiritual movements. But, their impact can be seen as a double-edged sword. Using one hand, it's provided a framework for individuals a course in miracles  seeking spiritual growth and inner peace. On one other hand, their teachings can contribute to a culture of spiritual bypassing, where individuals use spiritual ideas in order to avoid coping with particular and cultural issues. This could cause a form of escapism, where in actuality the concentrate on religious attitudes distracts from the requisite of participating with and addressing real-world challenges.

More over, the industrial achievement of ACIM and their related products raises ethical concerns. The expansion of workshops, publications, and seminars predicated on ACIM is visible as capitalizing on individuals' spiritual wants and vulnerabilities. Experts fight that the commercialization of spirituality can cause the exploitation of seekers, who might spend substantial time and money in to practices that eventually do not provide on the promises. This commercialization can also donate to the dilution of the course's teachings, as various understandings and changes proliferate, possibly leading to distress and misapplication of the principles.

Still another important part to consider may be the exclusivity and dogmatism that could sometimes accompany the ACIM community. Whilst the program itself promotes common love and forgiveness, the way it's shown and used by some adherents can result in an expression of spiritual elitism. This could produce an "us versus them" mentality, wherever those who follow ACIM are regarded as enlightened, while those that do not are viewed as misguided or unenlightened. Such attitudes could be divisive and detrimental to the course's supposed goals of peace and unity. Critics fight that correct spiritual growth must foster inclusivity and humility, rather than creating a hierarchical distinction involving the spiritually awakened and the unawakened.
