„Introduction to: Reformed Theology: Identity and Ecumenicity“, in: Michael Welker, Wallace Alston (Hg.), Reformed Theology: Identity and Ecumenicity, Grand Rapids: Eerdmans, 2003, IX-XIV.

How can Reformed theology preserve its identity and claim its ecumenicity while facing the 21st century? We have been challenged by postmodernism, religious pluralism, new age movements and neo-paganism, astrology, reincarnation thought, new technological secularism, and cyber-culture. Reformed theology – preserving its identity on the one hand, and claiming its ecumenicity on the other hand – needs to respond to these challenges creatively and to heal and guide the spirit of the 21st century.
