The Lebanese have a proverb: Kul wahad a'la dino, Allah ya'ino. Literally, this means: "To each his religion - God help him."
This wry piece of folk wisdom might be translated: "In matters of faith, expect people to be biased; mere humans simply cannot be expected to arrive at a balanced view of religion."
Although we are not necessarily aware of its influence on our daily life, religion is, in fact, a formidable force of identity. It develops in our personalities during childhood, quickly becoming second nature.
Religion can become a bridge of understanding among people or a wall of separation, depending on whether the guiding force in the faith is unconditional love or unconditional, literal dogma. Children learn fanaticism by imitating adults. When our son was seven, he asked me if Jesus was better than Muhammad. I froze, thought for a bit, and told him, "You know God through Christ and a Muslim child knows God through the Prophet Muhammad." He was satisfied.
All too often, though, due to ignorance, political insecurity, or the misinterpretation of scripture, children are taught that other people's beliefs are lies. Children who are thus indoctrinated build a mental wall around their community and start to think of people from other religions as dangerous.
This form of prejudice is quite common, even in societies where racism, sexism, and nationalistic chauvinism are generally rejected. When I worked for the World Council of Chuches, one theologian once shared a candid thought with me: "In a sense, literal religion can be fratricidal by structure." He meant that when dogma is taken too literally, it carries the seeds of violence, which are all too easily exploited by those in political power.
This is nowhere more apparent than in the Middle East. Centuries of political intimidation have convinced most Middle Easterners to avoid critical thinking in interpreting the sacred word. Religious authorities - Christian, Jewish, and Muslim - have too often used their power over their communities by discouraging genuine and full dialogue among communities of faith. Meanwhile, Israel's national and foreign policy is explicitly articulated around religious narratives.
