Who goes to warfare any time at his own expense? who plants a vineyard, and eats not of the fruit thereof? or who feeds a flock, and eats not of the milk of the flock?
All Commentaries on 1 Corinthians 9:7 Go To 1 Corinthians 9
Cornelius a Lapide
AD 1637
Who goeth a warfare any time at his own charges? Just as it is right for soldiers to be paid and to live in their pay; just as it is right for a vine-grower to eat of the fruit of his vine, for a shepherd of the milk of the flock that he feeds, so is it right for the preachers of the Gospel to live of the Gospel, of their vineyard the Church, and of their flock, the members of Christ. The Apostle is beginning here to prove in various ways his right to receive payment for his preaching, that all after him might know that this is owing to preachers of the Word of God, and that he may show how undeniable and how clear is the right that he has freely given up by refusing to receive payment out of regard to the Corinthians. He so acted in order that by this generosity of his he might draw them to Christ and help forward their salvation. I will summarise his reasons at ver12.
