Via Street Prophets, comes more information about the convergence of holy observances in the Abrahamic faiths. There's actually a project called The Tent of Abraham, Hagar, and Sarah that is calling for a interfaith observance on Oct. 13th. Some background:

In other periods of history, this group would have made unlikely bedfellows.

The first is a small Jewish community that has always been against the oppression of Palestinians.

The second is a small group of Muslims who are opposed to the fundamentalist definition of "jihad" as military struggle rather than as the interior struggle to be holy.

The third is a small group of Christians who have no doubts about the sins of Christianity against both these communities and, even more, a memory of Francis of Assisi, who in the midst of a Crusade against Egypt, crossed the battle lines to talk to Sultan Malik al-Kamil.

Francis, to convert the Egyptians, tried to strike a bargain: He would go into a fiery furnace and, if he came out alive, the Egyptians would convert to Christianity. Al-Kamil's answer to Francis was a gentle and a wise one. Gambling with one's life, he argued, is not a valid proof of one's God. Then, both of them wiser, he spared Francis' life and sent him on his way again.

Like Francis, these people have decided to do what their governments won't do. They are stepping across battle lines.

They are reaching out as friends to one another in formal, public ways. They are listening to the spirit in the heart of the other.

They call their project The October Surprise. The surprise is that the Jewish High Holy Days, the Islamic Month of Ramadan and the Christian feast of St. Francis of Assisi who opposed the Crusades and learned from an Islamic teacher, all come in October.

Check out the Tent of Abraham web site for more information. I like "Abrahamic convergence" better than "October Surprise" though :)
