A reflection on Justin Welby’s first five years as Archbishop of Canterbury February 20, 2018 by Fulcrum On the 21st March Justin Welby will mark the fifth anniversary of his enthronement as the 105th Archbishop of Canterbury. It is a significant moment for both him and the Church of England. Justin Welby has certainly brought energy, dynamism to the job, but aspects of his tenure have not gone well. Now is a good time to look back and consider. Mark Fox. Reaction. 16 February 2018 FulcrumShareTweetShare
