I am glad I came here for this Lambeth and worshipped one last time in the Cathedral home of Augustine and Dunstan, Anselm and Becket, Cranmer and Laud, Temple and Ramsay. I had come to speak a word of hope and perhaps to intervene on behalf of our beloved, but in the last resolve the family refused the long needed measures. So he just slipped away, our noble prince, one dreary morning in Canterbury with hardly even a death rattle.
I assume "he" here means the Anglican Communion as we know it.
The new prince was born last month in Jerusalem. I was there—arriving late, departing early. I was never quite sure what I was witnessing. It was an awkward and messy birth. He hardly struck me as I gazed upon him there in the bassinet as quite ready to be heir to the throne. I even wondered at times if there might be some illegitimacy to his bloodlines. But that I fear was my over wedded ness to a white and European world. May he live long, and may his tribe increase—and may he remember with mercy all those who merely mildly neglected his birth.
The "new prince" here clearly refers to GAFCON.
As for me my role for now is clear, to hold together as much as I can for as long as I can that when he comes to his rightful place on St. Augustine’s throne in Canterbury Cathedral he will have a faithful and richly textured kingdom.
I'm not sure if the "he" referred to here is GAFCON or someone else, since whoever it is, they are to sit upon the throne of St. Augustine of Canterbury, and they have a kingdom. Perhaps he means a future orthodox AoC as Sionnsar says, perhaps one in communion with GAFCON. The reference to him having a "kingdom" made me think he was possibly refering to Christ, who is of course king and lord of all. Anyways, the good man's diary scribblings may not be worth all this parsing, but I was confused about it.
I think you have it correct. At least I parsed it the same way. *\;-) The last, to me, reads GAFCON.
