3 There is an episode in the life of Saint Francis that shows his openness of heart, which knew no bounds and transcended differences of origin, nationality, colour or religion. It was his visit to Sultan Malik-el-Kamil, in Egypt, which entailed considerable hardship, given Francis’ poverty, his scarce resources, the great distances to be traveled and their differences of language, culture and religion. That journey, undertaken at the time of the Crusades, further demonstrated the breadth and grandeur of his love, which sought to embrace everyone. Francis’ fidelity to his Lord was commensurate with his love for his brothers and sisters. Unconcerned for the hardships and dangers involved, Francis went to meet the Sultan with the same attitude that he instilled in his disciples: if they found themselves “among the Saracens and other nonbelievers”, without renouncing their own identity they were not to “engage in arguments or disputes, but to be subject to every human creature for God’s sake”. In the context of the times, this was an extraordinary recommendation. We are impressed that some eight hundred years ago Saint Francis urged that all forms of hostility or conflict be avoided and that a humble and fraternal “subjection” be shown to those who did not share his faith.
