At the core of A Class in Wonders is just a non-denominational method of spirituality that encourages pupils to question their preconceived notions about reality, the self, and the world. The writing is divided in to three components: the Text, the Book for Students, and the Handbook for Educators, each offering a specific perception on the material presented. The key teachings of ACIM may be distilled in to a few crucial principles.

One of many central themes of ACIM is the concept of forgiveness. The Class shows that forgiveness is not just pardoning some one for their wrongdoings, but instead, it's the recognition that there's nothing to forgive. It asserts that what we understand as wrongdoings are acim the result of our own misperceptions and projections. In forgiving the others, we are, actually, flexible ourselves. ACIM emphasizes that forgiveness is a road to inner peace and liberation from the burdens of resentment and anger.

Yet another simple principle of A Class in Wonders could be the idea that the bodily world can be an illusion. It posits our sensory experiences are unreliable indicators of fact and that true perception can only just be performed via a shift in consciousness. The Class distinguishes between the "real-world," which is a state of peace and oneness beyond the material realm, and the "pride world," known by concern, separation, and conflict. According to ACIM, our principal function is to awaken from the desire of the pride earth and come back to the awareness of our divine nature.

ACIM also introduces the thought of the Sacred Soul as helpful tips and instructor within the individual. That religious existence sometimes appears as the foundation of enthusiasm and wisdom, helping people make choices that lead people closer to reality and from illusion. The Program shows that through our willingness to be controlled by the Holy Spirit's advice, we can access a deeper understanding of our function and the way to healing.
