基督宗教之人觀有二重思想：人是天主的肖像，但人也有限的受造物。前者說明人之超越能力，後者說明人與現實世界的關係。在詮釋此二思想時，受到當時「理智」(Logos)與「命運」(destiny)的影響，命運之概念與生命有關。上帝是「生命」，人則分享上帝的生命。但人生命是存在歷史中之發展過程，人之生命有始有終，其終極命運即與上帝結合。但人生命之發展，必須依靠來自其理智之「光」，人之理智分享上帝之光，而人理智之終極命運，即在永恆的光中，默觀上帝的真相。 人是上帝的肖像指人能反映上帝，而人之反映上帝，可從其結構及功能二方面視之。人之理智能認識一切，而在認識時，產生「心語」，心語之表達，能揭開事物之真，使人能肯定事物存在之根源。從功能的角度而言，人是上帝的肖像，指人受託保護管理宇宙，使之能參與上帝的化工。再者，人是上帝的肖像也指人之團體性。人在團體中表達其「授與受」的行動，反映其愛的能力。上帝是愛，而愛的關係使人肖似上帝。 本文首先說明對「人是上帝肖像」的理解，其次說明此概含因受「理智」的影響，成為基督宗教建立天人關係的基礎，最後說明「位格人」之概念，如何因上帝的肖像發展而成。

　　　　　According to the Christian view of human being, two ideas prevail: human being is the image of God and he is also creature. The former sees human nature as transcendent, the latter as limited and related to the world. When the necessity of interpreting the meaning of these ideas arises, the two current philosophical notions were borrowed: "logos" and "destiny." Destiny is related to life and human being shares the life of God. As life process is a historical and existential becoming with a beginning and an end, its ultimate end is union with God. However, the process of becoming takes place under the guidance of the "light" of human intellect, and according to Christian tradition, this light is a reflect of the divine "Light." In this way, the destiny of human intellect is the contemplation of divine truth in eternity. Man is the image of God means that human being is a reflection of God, and this reflection can be seen in his structure and mission. In principle, human intellect can know all things, and in the process of knowing, it produced a "mental word", the expression of this word reveals the truth nature of things and enables it to affirm the ground of their existence. From the point of view of mission, to human being is entrusted the protection and administration of the world. In this way, man participates in the "work" of God. "The image of God" also refers to the social nature of human being. The "give and take" of human life is fully exercised in human community. The power to give and to take is the expression of love. As God is love, the image of God means the refection of this love. This paper attempts first to understand theoretically the notion of "Logos." Then, it explains how it becomes the key notion in the Christian understanding of "Heaven-Man" relation. Finally, it tries to see how later on the notion of "human person" develops from it.
