In a speech delivered at General Synod, the Archbishop talked about Bishop Alastair's commitment to the Diocese of Derby in the deaneries and in schools.
Archbishop John (pictured right) said: "Alastair, you have overseen the development of new ‘super deaneries’ in the diocese where the area deans are paid half-time in that role (with the other half of the stipend for their parish ministry).
"I understand it has been a joy to see the eight area deans grow into their leadership roles and plan mission and ministry locally and contextually.
"You have spoken time and time again of the mission opportunities our church schools afford and have built up a first-rate team under an outstanding Director of Education."
Archbishop John also cited Bishop Alastair's work in the fight against human trafficking: "Of course, Alastair we are all impressed with the work you have done to highlight the horror that is modern slavery and the huge amount of effort you have given to leading on this area not only for the Church of England but for all denominations to ensure this matter is taken seriously."
He concluded by saying: "Your vast wisdom and deep spiritual leadership will be greatly missed both in the Diocese and in the life of the national church."
