The June 2009 issue of the journal Ecumenical Trends published by the Graymoor Ecumenical & Interreligious Institute includes Timothy MacDonald's review of Catherine E. Clifford, A Century of Prayer for Christian Unity (Eerdmans, 2009), to which I contributed the chapter "Baptists, Praying for Unity, and the Eschatology of Ecumenism." Other contributors included Cardinal Walter Kasper and the late George Tavard.
I'm able to link the review here for the time being, as a PDF of the entirety of the June 2009 issue is featured on the Ecumenical Trends page of the Graymoor site as the free sample issue.
This issue also includes articles on the Trinitarian ecclesiology of Miroslav Volf and the work of the Institute for Ecumenical Research in Strasbourg, France, as well as a reflection by Michael Kinnamon, General Secretary of the National Council of the Churches of Christ in the USA, on the ecumenical advocacy work of the NCC with reference to the United Nations.
In the event that the June 2009 issue ceases to be posted online as the free sample issue in the near future, here's the print citation for the review: Ecumenical Trends 38, no. 6 (June 2009): 12-13.
