The Gospel according to Spiritism is one of the five books that make up the Spiritist Codification, a set of teachings transmitted by high order spirits, and organized and commented upon by Allan Kardec. This work contains the essence of the moral teaching of Jesus, and therefore is a refuge where the followers of all religions and even those who have no religion – may join hands, because it offers a sure itinerary for our inner reform, the objective indicated by Christ as indispensable for achieving our future happiness and inner peace: that achievement which only the full observance of the divine laws can provide to the spirit on its gradual evolutionary path toward God.
