Paul did not command church leader to be celebate. He did say if the sex drive could not be controled, then they should get married. In fact he said bishops should be the husband of one wife and his children must be ruley.
Why does the CC command something that the NT does not command but encourages marriage when celebacy is not possible. Sure would solve a lot of problems for the CC if they’d let their priest be married: less sexual problems and more priest.
1 Timothy 3:
1 ¶ This is a faithful saying: If a man desires the position of a bishop, he desires a good work.
2 A bishop then must be blameless, the husband of one wife, temperate, sober-minded, of good behavior, hospitable, able to teach;
3 not given to wine, not violent, not greedy for money, but gentle, not quarrelsome, not covetous;
4 one who rules his own house well, having his children in submission with all reverence
5 (for if a man does not know how to rule his own house, how will he take care of the church of God?);
6 not a novice, lest being puffed up with pride he fall into the same condemnation as the devil.
7 Moreover he must have a good testimony among those who are outside, lest he fall into reproach and the snare of the devil.
Two quotes from St. Paul. : 1 cor 7:1-9
1 Now concerning the thing whereof you wrote to me: It is good for a man not to touch a woman. 2 But for fear of fornication, let every man have his own wife, and let every woman have her own husband. 3 Let the husband render the debt to his wife, and the wife also in like manner to the husband. 4 The wife hath not power of her own body, but the husband. And in like manner the husband also hath not power of his own body, but the wife. 5 Defraud not one another, except, perhaps, by consent, for a time, that you may give yourselves to prayer; and return together again, lest Satan tempt you for your incontinency.
2 “Have his own wife”… That is, keep to his wife, which he hath. His meaning is not to exhort the unmarried to marry: on the contrary, he would have them rather continue as they are. (Ver. 7: 8.) But he speaks here to them that are already married; who must not depart from one another, but live together as they ought to do in the marriage state.
6 But I speak this by indulgence, not by commandment. 7 For I would that all men were even as myself: but every one hath his proper gift from God; one after this manner, and another after that. 8 But I say to the unmarried, and to the widows: It is good for them if they so continue, even as I. 9 But if they do not contain themselves, let them marry. For it is better to marry than to be burnt. 10 But to them that are married, not I but the Lord commandeth, that the wife depart not from her husband.
6 “By indulgence”… That is, by a condescension to your weakness.
9 “If they do not contain”… This is spoken of such as are free, and not of such as, by vow, have given their first faith to God; to whom if they will use proper means to obtain it, God will never refuse the gift of continency. Some translators have corrupted this text, by rendering it, if they cannot contain. St Paul says that if you are too WEAK to remain Celibate then get married. Again I say there is nothing wrong with married clergy, The Church has simply stated that celbiacy is the highr calling because of this (in part):
1 Cor 7:31-35
31 And they that use this world, as if they used it not: for the fashion of this world passeth away. 32 But I would have you to be without solicitude. He that is without a wife, is solicitous for the things that belong to the Lord, how he may please God. 33 But he that is with a wife, is solicitous for the things of the world, how he may please his wife: and he is divided. 34 And the unmarried woman and the virgin thinketh on the things of the Lord, that she may be holy both in body and in spirit. But she that is married thinketh on the things of the world, how she may please her husband. 35 And this I speak for your profit: not to cast a snare upon you; but for that which is decent, and which may give you power to attend upon the Lord, without impediment.
That should answer your question about celibacy I think. It is not a requirement, but a GOOD thing.
