In this paper I discuses the ways in which the religious culture of the Joseon dynasty through 'Munheuimyo(文禧廟) shrine Ritual' of Joseon Royal Family, which were performed as Joseon dynasty national rituals(國家儀禮) by analyzing its formation and character. Munhoseja(文孝世子), the first son of king Jeongjo(正祖) who was the Crown Prince while he was alive but who died early and childless became the object of worship. Originally, he could not be made the object of public ritual for he was not parents of a king. There was no precedent for it. Therefore, according to the principle of differentiation between proper rituals(正祀) and improper rituals(淫祀) It would have to be classified as improper rituals(淫祀). But it was officially adopted as part of the national rite without any controversy. This ritual was preserved even after the passing of the kings who had originally performed it and led to the inception of Sejamyo ritual(世子廟儀禮). To fully understand the background and motivation for why it could be formed without any controversy, this paper is put on the two elements. In the motivation of Sejamyo(順懷廟) ritual which practiced as the first same case During king Myeongjong’s(明宗) reign and sovereign strengthening from SukJong's(肅宗) reign to Jeongjo's(正祖) reign. This ritual's characteristic is that worshipped the same as the Crown Prince as he was alive. This represents that day social circumstance that the importance the first son as a center of a family and lineage. Also, It means the outcome of sovereign strengthening of former king reign is to expanded to the rituals of Joseon Royal Family. Through the formation of this ritual, an ancestor lineage of childless biological sons of the royal-family was formed.
