This paper examines the spirituality of the 'point vierge' (virgin point) in Louis Massignon's thought, a core concept in his Christian theology of Islam. Influenced by the mystical spirituality of Al-Hallaj and the feminine spirituality of Mary, Massignon defined the 'virgin point' as the deepest and indestructible part of the heart, open to the presence of God - the Mysterious Stranger. Through fasting and silent acceptance, the Word, Jesus Christ, enters human life, making it spiritually fruitful. The article explores the theological roots of this idea and its significance in Christian-Islamic dialogue, highlighting how Massignon integrated elements of both traditions into this profound vision of spirituality.
