The Archbishop of Sudan, the Most Reverend Daniel Deng, is in Alexandria at the moment. He again called for the resignation of the Right Reverend Gene Robinson, the openly gay bishop of New Hampshire, and of the clergy those who consecrated him. Deng last summer shocked Anglicans by issuing a statement condemning the 2003 decision to consecrate Robinson, a non-celibate gay man, and the US bishops responsible for his appointment.
The position was supported by the Episcopal Church of Sudan, which with has four million followers, 300 primary schools and 24 dioceses. It had previously remained neutral on the issue of homosexuality. The unexpected statement was of special concern for the US Episcopal Church, which enjoys close ties to the African country.
On the penultimate day of a meeting between the world's archbishops and senior bishops to address regional and international concerns, Deng was asked whether he had changed his stance on Robinson and the US Episcopal Church.
He replied: "We are asking that within the primates meeting and the situation on the statement remains the same. We have not deviated. What is needed is for churches in the Anglican world to wrestle with these issues so it comes to an end."
His comments could cast a shadow over the candid, yet cordial conversations that have been taking place between primates during the week.
Delegates have described the atmosphere as constructive and collegial and a contrast to the rancorous and confrontational nature of their 2007 meeting in Tanzania.
Deng's comments will disappoint those who were keen to minimise public comments on homosexuality; he is the first primate to break ranks and reiterate the unresolved differences between some Anglican provinces and his response overshadowed his other appeal - for fellow primates to lobby their governments to press for peace and reconciliation in Sudan.
He said: "I strongly ask the Anglican Communion not to abandon the people of Sudan in this time of danger and uncertainty.
"I appeal to to above all do something so that the Comprehensive Peace Agreement may not slip away."
Signs of strain are beginning to show. The archbishops of Nigeria and Uganda failed to appear for a group photograph in the hotel grounds, nor did they materialise for a high-profile visit to the prestigious Alexandrian Library.
