7 For a bishop,  as God's steward, must be blameless; he must not be arrogant or quick-tempered or addicted to wine or violent or greedy for gain; 8 but he must be hospitable, a lover of goodness, prudent, upright, devout, and self-controlled. 9 He must have a firm grasp of the word that is trustworthy in accordance with the teaching, so that he may be able both to preach with sound doctrine and to refute those who contradict it.
Matthew Henry's Commentary on Titus 1:7-9
Commentary on Titus 1:5-9
(Read Titus 1:5-9)
The character and qualification of pastors, here called elders and bishops, agree with what the apostle wrote to Timothy. Being such bishops and overseers of the flock, to be examples to them, and God's stewards to take care of the affairs of his household, there is great reason that they should be blameless. What they are not to be, is plainly shown, as well as what they are to be, as servants of Christ, and able ministers of the letter and practice of the gospel. And here are described the spirit and practice becoming such as should be examples of good works.
