The Greek word translated self-controlled in Titus 1:8, is egkrates. This adjective only occurs here in the New Testament, though the noun form enkrateia is found numerous times (ex: Acts 24:25, Galatians 5:23, 2 Peter 1:6).
Thayer defines the term: having power over, possessed of (a thing). Mastering, controlling, curbing, restraining. Strong defines the term: strong in a thing (masterful); self-controlled (in appetite, etc.) temperate.
An elder needs to have mastery over his desires and inclinations. When God created us with desires, He intended us to interact in accord with His will. We are told to “be angry, and do not sin” (Ephesians 4:26). That the marriage bed is honorable and “undefiled; but fornicators and adulterers God will judge” (Hebrews 13:4). That we are not to walk as the Gentiles walk, “in the same flood of dissipation” (1 Peter 4:4). An intemperate man is not worthy of the eldership.
In the New King James translation, the Greek term is translated “self-controlled” primarily because in modern English the term “temperate” (as found in the KJV) is used primarily regarding the use of alcohol. It is important to note that control over ourselves and our inclinations should be present in everything. “Whoever has no rule over his own spirit is like a city broken down, without walls” (Proverbs 25:28). It is a fruit of the Spirit (cf. Galatians 5:23), to be added to our faith (cf. 2 Peter 1:6). It will be present in every Christian who is pleasing God.
