Both from Maggi:

Some fascinating photographic interpretations of Jesus and his teaching; and

This talk from +Kenneth Stevenson, which I found helpful, especially this:
“A bishop is a Prime Minister – because he is there to initiate and articulate policy, and to respond to what is going on; and that means listening carefully to colleagues and others, as he tries to engender an atmosphere of trust where creative things can happen, as well as challenge the system – and people – when necessary. A bishop, too, is a Monarch – someone who has to handle the symbolism and the language of public liturgy and occasion, a sign and embodiment of catholicity, and therefore at times a little distant from the particularities of the Church. Then, a bishop has to act as Speaker – this is about ensuring fair play, like the other roles, not always easy or straightforward, especially in a culture where some are rather more ready than others to cast themselves in the role of oppressed minorities! And a bishop also has to be a scapegoat – someone who is the butt of frustration and sometimes aggression, and who gets blamed when things go wrong, sometimes with every justification. I knew all these roles as a parish priest, and I took them with me when I became a bishop, all too aware that one never gets them right.”
