Seeking to promote Christian unity in a divided world, The Anglican Centre in Rome provides a permanent Anglican Communion presence in Rome. Written to coincide with the 50th anniversary year of the centre, and offering an update to Frank Bliss's volume 'Anglicans in Rome', 'An Open Door' tells the story of the past 10 years of the centre and looks to its future. The book includes an appendix with the significant milestones of the last ten years and a brief historical record of the centre's 50 years. Archbishop Justin Welby and Cardinal Koch provide their own reflections in the introduction.
