Because the work of pastors is to apply themselves constantly to the service of Christ in his churches by the ministry of the word and prayer, and by watching for their souls as they that must give an account to him, the churches to which they minister have a pressing obligation to give them not only all due respect, but also to impart to them a share of all their good things, according to their ability. This must be so done that the pastors may have a comfortable supply and that they may not have to be entangled in secular affairs, and may also be able to exercise hospitality towards others. All this is required by the law of nature and by the express command of our Lord Jesus, who has ordained that they that preach the gospel should live by the gospel.
