Here's a list of the major english-speaking theological journals currently available. I try and keep track of what is emerging.
International Journal for Systematic Theology - high-calibre constructive Christian theology, publishing the best new work in the discipline
Modern Theology - scholarly articles addressing issues specific to the discipline of theology and wider issues from a theological perspective
Scottish Journal of Theology - an international journal of systematic, historical and biblical theology
Pro Ecclesia - a journal of catholic and evangelical theology
Ecclesiology - the journal for ministry, mission and unity
Theology and Sexuality - an international journal functioning primarily as a resource for those undertaking theological studies of sexuality and gender issues
Studies in Christian Ethics - an English-language journal devoted exclusively to questions arising in the field of Christian ethics and moral theology
