One of many major concerns with A Class in Miracles is its basis on channeling, an activity wherever Schucman stated to possess received dictation from an internal voice she identified as Jesus Christ. The reliance on channeling as the source of the course's teachings is difficult since it lacks verifiable evidence and can quickly be caused by emotional phenomena as opposed to divine revelation. Channeling is usually criticized as a subjective knowledge, extremely susceptible to the subconscious mind's impact, particular biases, and psychological projections. Without concrete evidence or external validation, the reliability of Schucman's experiences and the subsequent teachings of A Program in Miracles stay highly questionable.

More over, this content of A Class in Miracles diverges somewhat from traditional Christian doctrines and different established religious teachings. While it employs Religious terminology and methods, the program usually reinterprets and redefines these terms in manners which are inconsistent with their mainstream meanings. For instance, the program presents a metaphysical worldview that acim the illusory nature of the material world, training that the physical galaxy and all their activities are simply forecasts of the mind. This perception contrasts sharply with the teachings of conventional Christianity, which typically upholds the reality of the bodily world and the significance of Jesus' physical resurrection. The reinterpretation of core Religious values in A Class in Wonders raises questions in regards to the course's legitimacy as a real spiritual teaching, as it appears to be more of a syncretic blend of different metaphysical and new age a few ideas rather than an authentic extension of Religious doctrine.

Also, A Course in Miracles advances an application of religious skipping, stimulating people to ignore or deny their negative emotions and experiences as pure illusions. The course's increased exposure of viewing beyond the material earth to a greater religious reality can lead followers to avoid confronting and handling their mental and psychological issues. This process can be harmful, as it discourages people from seeking ideal support and support for his or her mental wellness problems, probably exacerbating their problems. Religious skipping undermines the importance of developing one's religious beliefs with the realities of individual existence, ultimately causing an imbalanced and potentially detrimental method of spirituality.

Furthermore, A Class in Miracles presents a deterministic see of reality, suggesting that everything that takes place is element of a divine program and that people don't have any real get a handle on over their lives. That perspective may foster a feeling of helplessness and passivity, unsatisfactory people from taking proactive steps to improve their situations or address injustices in the world. The indisputable fact that all enduring is an dream or element of a predetermined program can cause too little concern and action towards those people who are experiencing true pain and hardship. Additionally, it may promote an expression of religious elitism, where followers of the course may possibly view themselves as being more enlightened or spiritually advanced than the others, leading to judgment and divorce rather than consideration and unity.
