Remember that Jesus said:
Matthew 16:18 And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it. 19 And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.
These last words are of key importance, "whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven." As Jesus has clearly given His Church the backing of Heaven's power in everything that they decide.
Furthermore, if the verse is read as requiring an absolute necessity that a Bishop be married, it creates several inconsistencies, if not, blatant contradictions.
a. Jesus, the Bishop of our faith was never married.
b. We are supposed to imitate Jesus.
Second, the Apostles are bishops. We can prove this by remembering what St. Peter
said when Judas was replaced.
Acts 1:20 For it is written in the book of Psalms, Let his habitation be desolate, and let no man dwell therein: and his bishoprick let another take.
But there are a couple of Apostles who are not married. St. John the Evangelist and St. Paul.
Third, picking up on St. Paul.
a. He has revealed in Scripture that he is not married, as stated above and since he's an Apostle, he's a Bishop. Furthermore, he also says:
1 Corinthians 7:32 But I would have you without carefulness. He that is unmarried careth for the things that belong to the Lord, how he may please the Lord:33 But he that is married careth for the things that are of the world, how he may please his wife.
And this is actually the basis for the Catholic Teaching. Since the Catholic Church wants priests to be concerned only with doing God's will.
b. And, he is the one who appointed both St. Timothy and St. Titus as Bishops. So, was he contradicting himself?
1 Timothy 4:12 Let no man despise thy youth; but be thou an example of the believers, in word, in conversation, in charity, in spirit, in faith, in purity.
Hm? The footnotes are supposed to supplement or explain the text. But, I'm not really sure what you're talking about. Perhaps and example would help.
Well, ok. I don't want to make this too long. Perhaps this is enough to begin a conversation.
