What does Titus 2:8 mean?

Verse 8 continues the list of attributes which Paul began in verse 6. Here, Paul commands young men to have "sound speech." This trait, also seen in 1 Timothy 4:12, was taught consistently in the early church. This is speech which is beyond criticism, so that those who attack it shame themselves. This mirrors Peter's instructions in 1 Peter 3:15–16. There, Peter instructs Christians to live so that anyone who attacks their character will embarrass themselves in the eyes of others. At the same time, Peter commands a gentle, respectful approach, and a readiness to answer those who question our faith.

The discipline of "apologetics" is summarized by this idea. Verses such as these encourage believers to know the reasons for their beliefs, and be prepared to explain them. The Greek term is apologia, which literally means, "to give an answer." It has nothing to do with apologizing. Rather, it is about communicating Christian truth to those who doubt or oppose it. Paul clearly teaches young men to stand strong in this area of faith. The result is that opponents will have nothing negative to say about them, a point also made about the prophet Daniel (Daniel 6).
