There's an encouraging and challenging interview with Justin Welby by the evangelist J. John, done a few months ago, with an edited transcript published here at God and Politics. Here's a few snippets
What does it mean to be an Anglican?
It first of all means to be a Christian – to be a disciple of Jesus Christ. The most important decision any person can ever make is to become a disciple of Jesus Christ. It’s the best thing anyone can do. Secondly, they follow in a particular tradition, which varies around the world. (I love the clarity of this answer, so refreshing, no small print)
So Archbishop, what are your hopes for the Church of England, your hopes for Britain?
My hopes are for a Church that learns much more to disagree well and to cope with diversity, that is incredibly flexible, that holds to the traditions where they serve the gospel and is incredibly flexible about living in a rapidly changing culture and learns how to deal with that. A Church that grows in the number of the faithful, committed disciples of Jesus Christ, year in and year out, and has a new confidence in the gospel and, above all, a Church that is consumed by love for Jesus.
Archbishop, how can we pray for you?
You can pray first of all for wisdom to know what to do, because it’s sometimes very difficult. Secondly, for patience, to know when to do it, because timing is often everything. And thirdly, for courage to do it even when it’s going to be really difficult.
