φωτεινός

bright, luminous, full of light

Definition

The adjective φωτεινός describes something that is bright, luminous, or full of light. In its literal sense, it refers to physical radiance, as seen in the description of Jesus' transfigured clothing being 'bright as light' (Matthew 17:5). Figuratively, it describes spiritual or moral illumination. In Matthew 6:22 and Luke 11:34, Jesus uses it to describe the 'eye' as the 'lamp of the body,' teaching that if one's perception is spiritually healthy and focused on God ('single'), their entire inner being is filled with divine light. Luke 11:36 further expands this, stating that if the whole body is 'full of light' (φωτεινόν), it will be radiant, like a lamp's brilliance.

Biblical Usage

This word is used four times in the New Testament, exclusively in the Gospels of Matthew and Luke. It appears in teachings of Jesus about spiritual perception and in a narrative of divine revelation. In Matthew 6:22 and Luke 11:34-36, it is used metaphorically to describe the condition of a person's inner life—whether it is illuminated by God's truth or darkened. In Matthew 17:5, it is used literally to describe the supernatural, dazzling brightness of Jesus' appearance during the Transfiguration, directly associating the word with divine glory.

Etymology

Derived from the noun φῶς (phōs, G5457), meaning 'light.' The suffix -εινός forms an adjective meaning 'pertaining to' or 'full of.' Thus, φωτεινός literally means 'pertaining to light' or 'characterized by light.' It is a cognate of the more common adjective φωτεινός, and its meaning is directly tied to the central biblical concept of light as a symbol for God, truth, purity, and revelation.

Semantic Range

This word is theologically significant as it bridges physical and spiritual realities of light. It is central to Jesus' teaching on spiritual health and perception, defining a life oriented toward God as one that is internally 'luminous' and effective in the world (Luke 11:36). In Matthew 17:5, it directly describes theophany—a visible manifestation of God's glory in Christ. Understanding φωτεινός enriches reading by highlighting the biblical theme that true light, both literal and metaphorical, finds its source in the divine.

In the ancient world, light was a precious and powerful symbol. Unlike modern, instantly available electric light, oil lamps provided a fragile, valuable illumination against pervasive darkness. This made 'brightness' a more potent concept, associated with safety, guidance, purity, and divine presence. When Jesus spoke of the body being 'full of light,' his listeners would have intimately understood the value and necessity of a lamp burning brightly, making the spiritual analogy powerfully concrete.

φῶς (phōs, G5457) — The noun 'light,' the source or substance itself, whereas φωτεινός describes something as being characterized by that light. λαμπρός (lampros, G2986) — Often means 'bright, shining, splendid,' with a stronger connotation of brilliance, radiance, or magnificence, frequently used for fine clothing or celestial beings.
