The sensible application of ACIM's teachings can be a point of contention. Although some persons record positive transformations and particular development from following a class, others find the methods to be inadequate or even harmful. The course's increased exposure of forgiveness and enjoy is admirable, but authorities disagree that it may be excessively easy and naïve, declining to address the difficulties of individual associations and the need for boundaries and accountability. Additionally, the course's length and intense character could be frustrating for many people, resulting in burnout or disillusionment. Authorities declare that enough time and effort needed to accomplish ACIM might be better used on more empirically supported beneficial techniques or religious professions that have an established history of effectiveness.

The broader impact of ACIM on the spiritual and self-help communities can also be value considering. The class has inspired a substantial subsequent and has been incorporated into numerous New Age and spiritual movements. Nevertheless, their influence is visible as a double-edged sword. On a single give, it has provided un curso de milagros  a construction for persons seeking religious development and inner peace. On another give, its teachings may donate to a culture of religious bypassing, where individuals use spiritual ideas to prevent dealing with personal and cultural issues. This can lead to a questionnaire of escapism, where the focus on religious beliefs distracts from the requisite of participating with and approaching real-world challenges.

More over, the professional accomplishment of ACIM and their related products raises honest concerns. The expansion of workshops, publications, and seminars based on ACIM is seen as capitalizing on individuals' spiritual needs and vulnerabilities. Authorities disagree that the commercialization of spirituality can lead to the exploitation of seekers, who may possibly invest significant time and income into practices that fundamentally don't produce on the promises. That commercialization may also donate to the dilution of the course's teachings, as numerous understandings and adaptations proliferate, probably ultimately causing confusion and misapplication of the principles.

Yet another critical element to consider could be the exclusivity and dogmatism that may occasionally accompany the ACIM community. Whilst the course it self advances common love and forgiveness, the way it is taught and practiced by some adherents may lead to a feeling of spiritual elitism. This can create an "us versus them" mentality, wherever people who follow ACIM are viewed as enlightened, while those who don't are seen as misguided or unenlightened. Such attitudes can be divisive and counterproductive to the course's proposed objectives of peace and unity. Authorities fight that true spiritual development should foster inclusivity and humility, rather than making a hierarchical variance between the spiritually awakened and the unawakened.
