2. In which of his letters does Paul lay down qualifications for bishops?
1. A little wine (1Tim. 5:23).
This "little wine" was also prescribed for the sake of Timothy's stomach. Wine
was safer to drink than water in many places.
2. 1 Timothy and Titus (1 Tim. 3:1-7; Titus 1:5-9).
A bishop is literally an "overseer".
