Channing Moore Williams (1829–1910) was the first Episcopal bishop consecrated for Japan (1866), serving 44 years in that archipelago and China. He founded Rikkyo University (聖パウロ大学 Sei Pauro Daigaku, 'St. Paul's University'), which remains Japan's premier Anglican educational institution. Williams embodied the 19th-century missionary bishop's integration of pastoral care, institutional building, educational innovation, and apostolic perseverance in establishing a lasting Anglican presence in East Asia.

Channing Moore Williams exemplifies the pioneering missionary bishop whose integration of pastoral care, educational institution-building, and apostolic witness established a lasting Anglican presence in a non-Western cultural context. He is venerated in the Anglican Church of Japan, at Rikkyo University, and in missionary tradition as the apostle who brought Anglicanism to Japan and established sustainable indigenous structures for Christian witness and education.

Channing Moore Williams was born in Richmond, Virginia, in 1829, and studied at the University of Virginia and the Virginia Theological Seminary. He was ordained in 1855 and initially served as a missionary in China (1855–1866), where he learned Mandarin and established Episcopal presence in Shanghai and other treaty ports. His educational innovations and pastoral effectiveness earned recognition, and in 1866, the General Convention consecrated him Bishop of China and Japan—the first Episcopal bishop appointed to Japan. Williams returned to Japan, where he devoted his episcopate to establishing a self-governing Japanese church. He founded schools, trained Japanese clergy, established parishes in Tokyo, Yokohama, and other cities, and articulated a vision of inculturation in which the Japanese church would develop its own theological and liturgical expression within Anglican tradition. His greatest institutional achievement was the establishment of Rikkyo University (1874), which combined rigorous Christian education with Japanese intellectual culture and became the flagship of Anglican higher education in East Asia. Williams remained actively engaged in missionary work through the Meiji Restoration (1868) and beyond, navigating Japan's rapid modernization and religious pluralism. He retired in 1908 after 44 years of service and died on December 2, 1910. His legacy shaped the development of Anglican Christianity in Japan and remains visible in the Nippon Sei Ko Kai (Anglican Church of Japan) and in Rikkyo's continuing prominence.
