### Core Meaning & Semantic Range
The Greek word **tropḗ**, represented by `{{G5157}}`, means a **turn**, revolution, or variation. This term is exceptionally rare in scripture, appearing only **1 time** in **1 unique verse**. Its singular use, however, is foundational for understanding a key attribute of God's character: His immutability.
### Biblical Occurrences & Contextual Analysis
The sole instance of `{{G5157}}` is found in a description of God's perfect and unchanging nature. In [[James 1:17]], it states that every good and perfect gift comes from "the Father of lights, with whom is no variableness, neither shadow of **turning**." Here, the word is used to affirm that God is completely stable and consistent. Unlike celestial bodies that turn and cast shifting shadows, God's character and purpose do not waver or change in the slightest.
### Related Words & Concepts
Several words from its immediate context illuminate the meaning of `{{G5157}}`:
* `{{G3883}}` **parallagḗ** (variableness): Defined as "transmutation" or "fickleness," this word appears directly alongside `{{G5157}}`. Its use in [[James 1:17]] emphasizes that there is no fickleness or change of any kind in God.
* `{{G644}}` **aposkíasma** (shadow): Meaning "a shading off" or "obscuration," this word forms the memorable phrase "shadow of **turning**." It intensifies the concept by stating that not even the slightest hint or appearance of change can be found in God [[James 1:17]].
* `{{G3962}}` **patḗr** (father): This identifies the one who is without turning as the "Father of lights," the source of all that is good and perfect. God's role as the ultimate **father** is characterized by this absolute steadfastness [[James 1:17]].
### Theological Significance
The theological weight of `{{G5157}}` is centered on the doctrine of divine immutability.

* **Reliability of God's Gifts:** This immutability is directly linked to His goodness. Because the "Father of lights" `{{G3962}}` `{{G5457}}` does not turn, every "good" `{{G18}}` and "perfect" `{{G5046}}` gift that "cometh down" `{{G2597}}` from Him is trustworthy and constant [[James 1:17]].
* **Contrast with Creation:** By referencing the "Father of lights" and the "shadow of **turning**," the verse contrasts God with the created universe. While heavenly bodies rotate and change, God, their Creator, remains eternally fixed and true.
