The office of pastor is not one that is to be attained to lightly. If a man desire the office of bishop, he desireth a good work (1st Timothy 3:1). But what is required of such a one? In order to be called a bishop, one must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach...not a novice, lest being puffed up with pride he fall into the same condemnation as the devil. Moreover he must have a good testimony among those who are outside, lest he fall into reproach and the snare of the devil. (1st Timothy 3:2-7). And what is required of him once he takes to the office? Richard Baxter, from The Reformed Pastor:
The nature of our office requireth us to ‘take heed to the flock.’ What else are we overseers, for “Bishop” is a title which intimates more of’ ‘labor than of honor,’ says Polydore Virgil.’ To be a bishop, or pastor, is not to be set up as an idol for the people to bow to, or as idle ‘slow bellies,’ to live to our fleshly delight and ease; but it is to be the guide of sinners to heaven. It is a sad case that men should be of a calling of which they know not the nature, and undertake they know not what.
If you miscarry, they and you may perish. You have a subtle enemy, and therefore you must be wise. You have a vigilant enemy, and therefore you must be vigilant. You have a malicious and violent and unwearied enemy, and therefore you must be resolute, courageous and indefatigable.
