Riah is the first contact of the Foundation. At first he gave his support to various ad hoc projects. In consultation with him a start was made of the scholarship project. In 1998 Riah was ordained 13rd Anglican Bishop of the Diocese of Jerusalem and head of the Episcopal Church in Jerusalem and the Middle East. in 2007 he was accorded emeritus status. He was priest of Christ Church in Nazareth when members of the student parish visited him in 1980. The reason for this visit was an impressive interview on the position of Palestinians in Israel given by him to Dutch radio.
He was an active member of PLP, the Progressive List for Peace, a political party in which Jews and Palestinians joined forces. Although it existed from 1984 until 1992 only it opened new horizons and broke several taboos. Under his leadership the day care center and primary school of the Anglican church in Nazareth was extended. Riah was a teacher and later headmaster at that school. The school was finally given permission to provide secondary education and developed into Riah Abu El-Assal Highschool, and later into Bishop Riah Educational Campus.
