It has always been the Taoist doctrine that "Confucianism, Buddhism, and Daoism are one" and that "Confucianism, Buddhism, Daoism, Yahweh, and Islam are of the same origin." The founder Wang Jue Yi was a Qing scholar who advocated “Essence is from the source" and believed that The Dao is the essence that creates all things in the universe, the eternal and unchanging truth, and the only way to return to the Source. In human beings, it is called the Essencial Mind Method, the Buddha-nature. In the period of the last Fa, the world has lost its roots, and only by seeking the Dao and teaching it can it transcend life and death. Return to “Wu Ji Li Tian“, the origin.

一貫道宗旨：

敬天地，禮神明，愛國忠事，敦品崇禮，孝父母，重師尊，信朋友，和鄉鄰，改惡向善，講明五倫八德，闡發五教聖人之奧旨，恪遵四維綱常之古禮，洗心滌慮，借假修真，恢復本性之自然，啟發良知良能之至善，己立立人，己達達人，挽世界為清平，化人心為良善，冀世界為大同。 

一貫道教義主張「儒、釋、道三教合一」、「儒、釋、道、耶、回五教同源」。 創教人王覺一為清代理學家，主張「性即理」，認爲

道是創生宇宙萬物的本體、永恆不變的真理，也是返回理天的唯一道路。 在人身上稱為性理心法、本元佛性。 末法時期，世人迷失根本，唯有求道授記，才能超生了死。 回歸「無極理天」。 

王覺一祖的宇宙觀：理、氣、象

理者，無極之真也。未有天地，先有此理，天地窮盡，此理復生天地。

王覺一祖接受邵康節以元、會、運、世為宇宙一終始的循環理論。以子會開天，丑會闢地，寅會生人、戌會閉物等視為天地萬物的生成過程，周而復始的生滅循環。其中涵蓋著宗教救劫的精神。

王祖認為理天乃「性命之大源」，將「人」的本體提升與宇宙本體相同的地位，建立形而上、本體的人性論。他認為，人性具有與理天相同的特質，理天是理的全體，人性則是理的分殊。人性既來自理天，因此必須還歸理天，理天者，萬物統體之至善；理性者，物物各具之至善。

他以為至善就是至理，達到理的極致。因此以至善説明理天的本質。理天的神妙是無法以文字囿限的，至善是「無聲無臭之天，無思無為之性」。

道心、元神倶出於理天，貫於個體之中，他所説「此神無時不與理天相通」，並非道心之外另有一神，而是道心、元神互通為一。

人性之本源於天，故人性至善光明無有不善。因後天氣稟之異而有善惡之分，以及降生後受物慾的遷累呈現惡的質性。只有恢復先天至善的本心，人人明善復初，返本還原，才能超出三界，不囿五行，獲大安樂，永不退轉。
