Unveiling the Word

In Biblical studies, understanding the nuances of specific Greek words is essential for grasping the deeper meanings embedded in the text. The word μῆκος (mēkos), which appears in Ephesians 3:18, is particularly significant because it is used to describe dimensions—specifically, length. This term helps convey the vastness of Christ’s love in the spiritual context, drawing attention to both physical and metaphorical dimensions. Understanding μῆκος allows for a richer interpretation of passages that use spatial language to describe abstract concepts like love, faith, or God’s power. Moreover, it gives insight into how ancient Greek culture measured and understood physical and metaphysical spaces.

Defining Meanings

Meaning 1: Length (Physical Dimension)
The primary meaning of μῆκος is physical length. This use is straightforward and typically appears in contexts related to measurements or descriptions of space. For example, in both classical Greek and New Testament writings, μῆκος is used to define physical spaces or dimensions of objects.
