1 Am I not free? Am I not an apostle? Have I not seen Jesus our Lord? Are you not my work in the Lord? 2 If to others I am not an apostle, at least I am to you; for you are the seal of my apostleship in the Lord.
3 My defense to those who examine me is this: 4
Do we not have a right to eat and drink? 5 Do we not have a right to take along a believing wife, even as the rest of the apostles and the brothers of the Lord and Cephas? 6 Or do only Barnabas and I not have a right to refrain from working? 7 Who at any time serves as a soldier at his own expense? Who plants a vineyard and does not eat the fruit of it? Or who tends a flock and does not use the milk of the flock?
8 I am not speaking these things according to human judgment, am I? Or does not the Law also say these things? 9 For it is written in the Law of Moses, “You shall not muzzle the ox while he is threshing.” God is not concerned about oxen, is He? 10 Or is He speaking altogether for our sake? Yes, for our sake it was written, because the plowman ought to plow in hope, and the thresher to thresh in hope of sharing the crops. 11 If we sowed spiritual things in you, is it too much if we reap material things from you? 12 If others share the right over you, do we not more?
Nevertheless, we did not use this right, but we endure all things so that we will cause no hindrance to the gospel of Christ. 13 Do you not know that those who perform sacred services eat the food of the temple, and those who attend regularly to the altar have their share from the altar? 14 So also the Lord directed those who proclaim the gospel to get their living from the gospel.
15 But I have used none of these things. And I am not writing these things so that it will be done so in my case; for it would be better for me to die than have any man make my boast an empty one. 16 For if I preach the gospel, I have nothing to boast of, for I am under compulsion; for woe is me if I do not preach the gospel. 17 For if I do this voluntarily, I have a reward; but if against my will, I have a stewardship entrusted to me. 18 What then is my reward? That, when I preach the gospel, I may offer the gospel without charge, so as not to make full use of my right in the gospel.
So it seems this isn’t saying what that one verse on its own led us to believe:
St. Paul is defending himself from an accusation. This list of things he has a right to, including taking a wife, is all to say he abstains from his reward for his preaching. It appears he tries to engage in nothing but preaching the gospel. His great concern is that by doing some of these (any of these things) he might hinder the gospel. How would he hinder the gospel by partaking of these things? Well he continues:
1 Corinthians 9:19-27 (NASB) said:
19 For though I am free from all men, I have made myself a slave to all, so that I may win more. 20 To the Jews I became as a Jew, so that I might win Jews; to those who are under the Law, as under the Law though not being myself under the Law, so that I might win those who are under the Law; 21 to those who are without law, as without law, though not being without the law of God but under the law of Christ, so that I might win those who are without law. 22 To the weak I became weak, that I might win the weak; I have become all things to all men, so that I may by all means save some. 23** I do all things for the sake of the gospel, so that I may become a fellow partaker of it.**
24 Do you not know that those who run in a race all run, but only one receives the prize? Run in such a way that you may win. 25 Everyone who competes in the games exercises self-control in all things. They then do it to receive a perishable wreath, but we an imperishable. 26 Therefore I run in such a way, as not without aim; I box in such a way, as not beating the air; 27 but
I discipline my body and make it my slave, so that, after I have preached to others, I myself will not be disqualified.
Okay, so we see here that he is doing this to build up his discipline. Not just to avoid taking his reward or taking more than was his due and give scandal, but also to improve his discipline and self-control. It’s fairly reasonable to say he has taken none of these things because they are not pertinent to his mission, his vocation: To preach the gospel. So this great apostle deemed it unwise to do or take any of these things. Ultimately it seems perfectly reasonable for the Church to ask her priests to take upon themselves one of these disciplines in the form of priestly celibacy to improve their self-control and (on a practical note) free them up to serve their flock. Both a family and a flock require full-time attention.
You’re on the right track! I’ve written this a touch quickly so apologies if I was unclear.
Good luck, and God bless!
