From the Church Times:
It began when the US Presiding Bishop, Dr Katharine Jefferts Schori, was requested by Lambeth Palace not to wear her mitre during a service at Southwark Cathedral a fortnight ago. Dr Jefferts Schori described the ban as “bizarre — it is beyond bizarre”.
Since then, the “Mitregate” saga has refused to die down. Last week end, another woman bishop from the United States, the Bishop of El Camino Real, the Rt Revd Mary Grey-Reeves, presided at the eucharist in Gloucester Cathedral. She was in Gloucester with the Bishop of West Tanganyika, the Rt Revd Gerard Mpango. Bishop Grey-Reeves was permitted to wear her mitre.
The Bishop of Gloucester, Dr Michael Perham, who invited Bishop Grey-Reeves, said in an explanatory note that the law governing visiting bishops from overseas needed urgent revision. He had none the less applied for, and been granted, permission for Bishop Grey-Reeves to officiate, under the provisions of the Overseas and Other Clergy (Ministry and Ordination) Measure of 1967.
Dr Perham writes: “The Measure makes no reference to what the bishop wears. . . On Sunday, when she stood at my side when I presided at the eucharist, and again when she preached at a Partnership Service later in the day, she did . . . wear her mitre.”
Diddle, diddle dumpling, Bishop Kate
Went to church with her mitre off.
One mitre off, and one mitre on,
Diddle, diddle dumpling, Bishop Mary
