The Greek word adiaphthoría, represented by G90, denotes incorruptibleness or the figurative purity of doctrine. This term is exceptionally rare, appearing only 1 time in 1 unique verse in the Bible. Its meaning is derived from a compound of a negative particle with a word for corruption, emphasizing a state of purity and soundness in teaching.
The single use of G90 is found in an instruction to Titus, where he is told to be a model for others. In the midst of a list of virtues, the text specifies, "in doctrine shewing uncorruptness" Titus 2:7. This places the word squarely in the context of teaching, linking personal integrity directly to the purity of the message being taught. The quality of uncorruptness is presented alongside gravity and sincerity as essential characteristics for a teacher.
Several related words in the immediate context of Titus 2:7 help clarify the meaning of G90:
- G1319 didaskalía (instruction, doctrine, learning, teaching): This is the direct subject to which uncorruptness must be applied. Believers are warned against being "carried about with every wind of doctrine" Ephesians 4:14, highlighting the need for the stability that G90 implies.
- G2041 érgon (deed, doing, labour, work): The call for uncorruptness in doctrine is part of a larger exhortation to be "a pattern of good works" Titus 2:7. This shows that sound teaching is itself a virtuous work that must align with a righteous life.
- G2570 kalós (good, honest, well): This adjective modifies "works" in Titus 2:7, establishing that the entire pattern of life, including one's teaching, should be visibly good and virtuous.
- G4587 semnótēs (gravity, honesty): This virtue is listed immediately after G90 in Titus 2:7, suggesting a probity and seriousness that should accompany pure doctrine.
- G861 aphtharsía (immortality, incorruption, sincerity): Also appearing in the list in Titus 2:7, this word's meaning of genuineness and incorruptibility strongly reinforces the concept of G90.
The theological weight of G90 is concentrated in its single appearance, establishing a clear standard for spiritual instruction.
- Doctrinal Integrity: The primary significance of G90 is its demand for purity in teaching. It stands as a guard against corrupt or deceitful doctrines, such as the "doctrines of devils" 1 Timothy 4:1 or teachings designed to please "itching ears" 2 Timothy 4:3.
- The Unity of Belief and Behavior: Its placement within the command to be "a pattern of good works" Titus 2:7 demonstrates that uncorrupt doctrine cannot be separated from a life of good deeds. What one teaches must be reflected in how one lives.
- A Standard for Leadership: The instruction is given to Titus as a leader. Therefore, G90 establishes a high standard of incorruptibility for those who teach and lead in the faith, as their words and life serve as a model for others.
In summary, although G90 appears only once, adiaphthoría carries significant weight. It defines the crucial quality of uncorruptness that must characterize biblical doctrine. Its sole mention in Titus 2:7 firmly links this doctrinal purity to a life of good works, gravity, and sincerity. The word serves as a concise and powerful reminder that the integrity of one's teaching is an essential part of an exemplary and God-honoring life.
