Scripture, prayer and worship are three key elements of the internal life of Christians across the world. Corporately or individually, Christians hear, read, enact and inhabit the bible. They pray alone, in twos and threes, and in large gatherings. They pray aloud or in silence. They pray spontaneously or following a common form of words. Christians sing songs and make music. They perform and recite liturgies. Such is the ubiquity of these elements that it seems surprising that it was not until 2018 that the Yale-Edinburgh Conference chose ‘Scripture, Prayer and Worship in the History of Missions and World Christianity’ as its theme. This special issue of Studies in World Christianity brings together six of the excellent papers that were presented at the conference. Together they offer a time frame of about two hundred years and an impressive global range – New Zealand, Argentina, India, USA and China. Although they only focus upon Protestant practice, the articles demonstrate how rich that practice has become.
