Theological investigation of the Μαρτνρια [witness] lexeme in John 1-4 contributes significantly towards an understanding of an emerging, missional ecclesiology. This hypothesis is precipitated by the accelerated pace of change that our society is currently experiencing. The technological developments of the past 50 years have created a society that is dependent on this new technology, leading to the developing of a new cultural paradigm, in which the church is ill at home. The question of an emerging, missional ecclesiology is therefore building on the need for theological research from the perspective of this developing new paradigm. It was proposed that a hermeneutic approach should be taken. It was also argued that ecclesiology serves as the integration point for reflection and practical missional ministry. As such, the church as object of investigation is the ultimate technological praxis, as the faith community serves as the show-case of God's presence in this world.
