Description: The Diffusion of Ecclesiastical Authority explores the leadership of the church in Acts from a sociological perspective. Two primary models emerge from a sociologically informed investigation of first-century Greco-Roman and Jewish religious leadership: ""manager-leader"" and ""innovator-leader."" An examination of seven passages in Acts reveals that the leaders of the early church, although initially conforming to cultural expectations, are best described as innovator-leaders whose counter-cultural actions resulted in the empowerment of new leaders and the advancement of the gospel. Through the use of fictive kinship language, the voluntary sharing of authority, the fostering of a sense of mutual dependence on God as the common patron, and the redefinition of what is honorable, the leaders in Acts consistently enabled others to share authority in the church.
