I corrected to wrong assumption that I made regarding the others’ opinion already.
Why should the discipline not been there? It’s encouraged (multiple times) by God Himself in the Scriptures, as well as by St. Paul.
The choice of celibacy for those called is, mandating it as a prerequisite for ordination is not.
The list of Saints (the celibate ones) is endless.
The list of Saints (the married ones) is endless, including St. Peter.
Where in the New Testament is it encouraged for a priest/bishop to be married *rather than *remain celibate?
I Timothy 3
1 Faithful is the saying, If a man seeketh the office of a bishop, he desireth a good work. 2 The bishop therefore must be without reproach, the husband of one wife, temperate, sober-minded, orderly, given to hospitality, apt to teach; 3 no brawler, no striker; but gentle, not contentious, no lover of money; 4 one that ruleth well his own house, having his children in subjection with all gravity; 5 (but if a man knoweth not how to rule his own house, how shall he take care of the church of God?) 6 not a novice, lest being puffed up he fall into the condemnation of the devil. 7 Moreover he must have good testimony from them that are without; lest he fall into reproach and the snare of the devil.
I Corinthians 7
Now concerning the things whereof ye wrote: It is good for a man not to touch a woman. 2 But, because of fornications, let each man have his own wife, and let each woman have her own husband. 3 Let the husband render unto the wife her due: and likewise also the wife unto the husband. 4 The wife hath not power over her own body, but the husband: and likewise also the husband hath not power over his own body, but the wife. 5 Defraud ye not one the other, except it be by consent for a season, that ye may give yourselves unto prayer, and may be together again, that Satan tempt you not because of your incontinency. 6 But this I say by way of concession, not of commandment. 7 Yet I would that all men were even as I myself. Howbeit each man hath his own gift from God, one after this manner, and another after that.
8 But I say to the unmarried and to widows, It is good for them if they abide even as I. 9 But if they have not continency, let them marry: for it is better to marry than to burn.
10 But unto the married I give charge, yea not I, but the Lord, That the wife depart not from her husband 11 (but should she depart, let her remain unmarried, or else be reconciled to her husband); and that the husband leave not his wife.
17 Only, as the Lord hath distributed to each man, as God hath called each, so let him walk. And so ordain I in all the churches. 18 Was any man called being circumcised? Let him not become uncircumcised. Hath any been called in uncircumcision? Let him not be circumcised. 19 Circumcision is nothing, and uncircumcision is nothing; but the keeping of the commandments of God. 20 Let each man abide in that calling wherein he was called.
21 Wast thou called being a bondservant? Care not for it: nay, even if thou canst become free, use it rather. 22 For he that was called in the Lord being a bondservant, is the Lord’s freedman: likewise he that was called being free, is Christ’s bondservant. 23 Ye were bought with a price; become not bondservants of men. 24 Brethren, let each man, wherein he was called, therein abide with God.
25 Now concerning virgins I have no commandment of the Lord: but I give my judgment, as one that hath obtained mercy of the Lord to be trustworthy. 26 I think therefore that this is good by reason of the distress that is upon us, namely, that it is good for a man to be as he is. 27 Art thou bound unto a wife? Seek not to be loosed. Art thou loosed from a wife? Seek not a wife. 28 But shouldest thou marry, thou hast not sinned; and if a virgin marry, she hath not sinned. Yet such shall have tribulation in the flesh: and I would spare you. 29 But this I say, brethren, the time is shortened, that henceforth both those that have wives may be as though they had none; 30 and those that weep, as though they wept not; and those that rejoice, as though they rejoiced not; and those that buy, as though they possessed not; 31 and those that use the world, as not using it to the full: for the fashion of this world passeth away.
