1:4 to Titus, my true child according to a common faith:
Grace, mercy, and peace from God the Father and the Lord Jesus Christ
our Savior.
1:5 I left you in Crete for this reason,
that you would set in order the things that were lacking,
and appoint elders in every city, as I directed you;
1:6 if anyone is blameless, the husband of one wife,
having children who believe, who are not accused of loose or unruly
behavior.
1:7 For the overseer must be blameless, as God's steward;
not self-pleasing, not easily angered, not given to wine,
not violent, not greedy for dishonest gain;
1:8 but given to hospitality, as a lover of good, sober-minded, fair,
holy, self-controlled;
1:9 holding to the faithful word which is according to the teaching,
that he may be able to exhort in the sound doctrine,
and to convict those who contradict him.
1:10 For there are also many unruly men, vain talkers and
deceivers,
especially those of the circumcision,
1:11 whose mouths must be stopped; men who overthrow whole houses,
teaching things which they ought not, for dishonest gain's sake.
1:12 One of them, a prophet of their own, said,
"Cretans are always liars, evil beasts, and idle gluttons."
1:13 This testimony is true.
For this cause, reprove them sharply, that they may be sound in the
faith,
1:14 not paying attention to Jewish fables
and commandments of men who turn away from the truth.
By the way, this style of rhetoric is a generalization, and Jesus himself uses such as for example in Mt 23 where he generalizes the characteristic behavior of scribes and pharisees. But this is not to say such is true in every particular case. Yes, the Bible does endorse such rhetoric. You're not lying in using generalizations.Now, at times we're called to respond gently. But not in this kind of case. In this kind of case, particularly involving those who view themselves with some spiritual authority and are teaching false doctrine, those are to be rebuked sharply. Likewise of elders it says, "Those who are sinning rebuke in the presence of all, that the rest also may fear." 1Tim 5:20 Note even in the gospels how Jesus dealt harshly with the religious elite in comparison with ordinary folk.
