Priest, scientist, social activist, and missionary, the Rev. Canon Wade Renn, 79, will retire from House of Prayer in Newark on June 29 after a 50-year ministry that has touched the lives of countless people. When asked what he cherishes most about his long and varied ministry, he answers without hesitation, “To have been called by God to be a domestic and foreign missionary of the Episcopal Church.” In 2005, at age 70, when not a few clergy have settled into less ambitious ministries, Renn founded a faith-based mission to the homeless in Montclair, providing shelter, food and showers for those in need. He remained president of the mission until 2012. It’s but one of many impressive accomplishments during a truly amazing life of service.
