An astute observer of religion has to pay attention to the current situation of Christianity and Islam, in all its forms. One person to listen to is Jesuit Father Samir Khalil Samir, a Cairo born Islamic scholar and Catholic theologian teaching at Saint Joseph’s University, Beruit; Father Samir is well-published and well-sought after for counsel on Christian-Muslim matters.

Today at Asia News, Father Samir has a keenly written article on Islam and Christianity as we know it right now. Really, you need to read this article.
