The emerging church is a response to the perceived influence of modernism in Western Christianity. As some sociologists commented on a cultural shift that they believed to correspond to postmodern ways of perceiving reality in the late 20th century, some Christians began to advocate changes within the church in response. These Christians saw the contemporary church as being culturally bound to modernism. They changed their practices to relate to the new cultural situation. Emerging Christians began to challenge the modern church on issues such as: institutional structures, systematic theology, propositional teaching methods, a perceived preoccupation with buildings, an attractional understanding of mission, professional clergy, and a perceived preoccupation with the political process and unhelpful jargon ("Christian-ese").
