Celibacy

Matthew 19
12 For there are some eunuchs, which were so born from their mother's womb: and there are some eunuchs, which were made eunuchs of men: and there be eunuchs, which have made themselves eunuchs for the kingdom of heaven's sake. He that is able to receive it, let him receive it.

James 2
18 Yea, a man may say, Thou hast faith, and I have works: shew me thy faith without thy works, and I will shew thee my faith by my works. 19 Thou believest that there is one God; thou doest well: the devils also believe, and tremble. 20 But wilt thou know, O vain man, that faith without works is dead? 

James 2
14 What doth it profit, my brethren, though a man say he hath faith, and have not works? can faith save him? 15 If a brother or sister be naked, and destitute of daily food, 16 And one of you say unto them, Depart in peace, be ye warmed and filled; notwithstanding ye give them not those things which are needful to the body; what doth it profit? 17 Even so faith, if it hath not works, is dead, being alone.

Matthew 24
42 Watch therefore: for ye know not what hour your Lord doth come. 43 But know this, that if the goodman of the house had known in what watch the thief would come, he would have watched, and would not have suffered his house to be broken up. 44 Therefore be ye also ready: for in such an hour as ye think not the Son of man cometh.

45 Who then is a faithful and wise servant, whom his lord hath made ruler over his household, to give them meat in due season? 46 Blessed is that servant, whom his lord when he cometh shall find so doing. 47 Verily I say unto you, That he shall make him ruler over all his goods. 48 But and if that evil servant shall say in his heart, My lord delayeth his coming; 49 And shall begin to smite his fellowservants, and to eat and drink with the drunken; 50 The lord of that servant shall come in a day when he looketh not for him, and in an hour that he is not aware of, 51 And shall cut him asunder, and appoint him his portion with the hypocrites: there shall be weeping and gnashing of teeth.

As we said there are Eunuchs which made themselves Eunuchs for the kingdom of God. So this is about people who devote their time to educational pursuits and humanitarian service like priests and nuns among others.

So how can we know if a Eunuch is a follower of Jesus or not? James says that it is people who has faith and has works. Because Judas Escariot himself has deceived Jesus because Jesus can see faith in Judas Escariot's cries. That is how the Escariot deceived, he proclaims faith like that of Pharisees where he can be seen by people. However there is no works.

That is the difference of a faithful and wise follower compared to that of an evil and lazy follower. There is weeping and gnashing of teeth because he is a baby.

1 Thessalonians 2
16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: 17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord. 18 Wherefore comfort one another with these words.

The dead in Christ are people of different beliefs, gentiles and atheists because there is a law written in their hearts to do good works. Naturally Jesus knows these people because he is a peacemaker and most probably have friends of different faith. These people understood first that the doctrines of Jesus makes sense and is for their own good.

2 Timothy 3
16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:

Romans 2
10 But glory, honour, and peace, to every man that worketh good, to the Jew first, and also to the Gentile: 11 For there is no respect of persons with God. 12 For as many as have sinned without law shall also perish without law: and as many as have sinned in the law shall be judged by the law; 13 (For not the hearers of the law are just before God, but the doers of the law shall be justified. 14 For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves: 15 Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another;) 

Yes, the Early Christians are friends with Jews and Gentiles who has good works.

Matthew 6
24 No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon.

This is why Jesus retired. So is there a contradiction because it says a Bishop can have one wife. This is a leader alright but there are instances that two or three people leads people.

Matthew 18
20 For where two or three are gathered together in my name, there am I in the midst of them.

Since a married individual cannot serve God full-time, two or three people can help in propagating the Church.

The First Triumvirate was a political alliance between three prominent Roman politicians (triumvirs) which included Gaius Julius Caesar, Gnaeus Pompeius Magnus (Pompey the Great) and Marcus Licinius Crassus. 

The Second Triumvirate is the name historians have given to the official political alliance of Gaius Octavius (Octavian, Caesar Augustus), Marcus Antonius (Mark Antony), and Marcus Aemilius Lepidus, formed on 26 November 43 BC with the enactment of the Lex Titia, the adoption of which is viewed as marking the end of the Roman Republic. The Triumvirate existed for two five-year terms, covering the period 43 BC to 33 BC. Unlike the earlier First Triumvirate,[2][3] the Second Triumvirate was an official, legally established institution, whose overwhelming power in the Roman state was given full legal sanction and whose imperium maius outranked that of all other magistrates, including the consuls. - Wikipedia.

And why Presidents have Vice-Presidents and staff.

The celibacy in serving the Church is the ideal cause there is no greater perseverance than celibacy cause you have to endure lust and corruption until your death. That is why priests after completing the seminary course and the nuns finished their education in the convents, they are to mingle outside to be in limbo.
