Logos is a Greek term meaning 'word' or 'reason,' which plays a crucial role in Christian theology, particularly in the context of understanding the nature of Christ and His relationship to God. It signifies the divine reason or plan that governs the universe and is closely linked to the concept of Jesus as the incarnate Word of God, as expressed in the opening verses of the Gospel of John. This understanding of logos has significant implications for Christianity's influence on philosophy, culture, and inter-religious dialogue.
