The priest in this picture is Frank Griswold, heretic Presiding Bishop of the Episcopal Church. He's one of the very vocal anti-Israel crowd in the ECUSA. Fitting that he'd be the special guest of the Palestinian terrorists.
Thank you so much for pointing out Griswold. I am very glad and proud to say I have "sent my letter" (of separation) to the Episcopal Church in which I was confirmed 20 years ago.
