Peter was soon eclipsed in this leadership by James the Just, "the Brother of the Lord," which may explain why the early texts contain scant information about Peter. According to Lüdemann, in the discussions about the strictness of adherence to the Jewish Law, the more conservative faction of James the Just gained the upper hand over the more liberal position of Peter, who soon lost influence. According to Dunn, this was not an "usurpation of power," but a consequence of Peter's involvement in missionary activities. The relatives of Jesus were generally accorded a special position within this community, also contributing to the ascendancy of James the Just in Jerusalem.
