Why it is necessary for a person to be baptized again that was baptized outside the teaching of the Apostles?

What does the Bible says?

 

Matthew 16:18-19

 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.

Act 19:1-6

 1 And it came to pass, that, while Apollos was at Corinth, Paul having passed through the upper coasts came to Ephesus: and finding certain disciples,

 2 He said unto them, Have ye received the Holy Ghost since ye believed? And they said unto him, We have not so much as heard whether there be any Holy Ghost.

 3 And he said unto them, Unto what then were ye baptized? And they said, Unto John's baptism.

 4 Then said Paul, John verily baptized with the baptism of repentance, saying unto the people, that they should believe on him which should come after him, that is, on Christ Jesus.

 5 When they heard this, they were baptized in the name of the Lord Jesus.

 6 And when Paul had laid his hands upon them, the Holy Ghost came on them; and they spake with tongues, and prophesied.

Ephesians 4:5

One Lord, one faith, one baptism,

 

 

Mark 16:16

 16 He that believeth and is baptized shall be saved; but he that believeth not shall be damned.

 

Galatians 3:26-27

26 For ye are all the children of God by faith in Christ Jesus.

 27 For as many of you as have been baptized into Christ have put on Christ.

Galatians 1:8-9

 8 But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed.

 9 As we said before, so say I now again, if any man preach any other gospel unto you than that ye have received, let him be accursed.

Colossians 2:11-14

 11 In whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ:

 12 Buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead.

 13 And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses;

 14 Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;

Romans 6:3-8

 3 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?

 4 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.

 5 For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:

 6 Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.

 7 For he that is dead is freed from sin.

 8Now if we be dead with Christ, we believe that we shall also live with him:

1 Corinthians 15:39-50

 39 All flesh is not the same flesh: but there is one kind of flesh of men, another flesh of beasts, another of fishes, and another of birds.

 40 There are also celestial bodies, and bodies terrestrial: but the glory of the celestial is one, and the glory of the terrestrial is another.

 41 There is one glory of the sun, and another glory of the moon, and another glory of the stars: for one star differeth from another star in glory.

 42 So also is the resurrection of the dead. It is sown in corruption; it is raised in incorruption:

 43 It is sown in dishonour; it is raised in glory: it is sown in weakness; it is raised in power:

 44 It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body.

 45 And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit.

 46 Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual.

 47 The first man is of the earth, earthy; the second man is the Lord from heaven.

 48 As is the earthy, such are they also that are earthy: and as is the heavenly, such are they also that are heavenly.

 49 And as we have borne the image of the earthy, we shall also bear the image of the heavenly.

 50 Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.

 

Romans 8:1-3

1 There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.

 2 For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.

 3For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:

Romans 8:29-30

29 For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren.

 30 Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified.

 

Revelation 16:15

 

 15 Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walk naked, and they see his shame.

 

Matthew 22:11-14

 11 And when the king came in to see the guests, he saw there a man which had not on a wedding garment:

 12 And he saith unto him, Friend, how camest thou in hither not having a wedding garment? And he was speechless.

 13 Then said the king to the servants, Bind him hand and foot, and take him away, and cast him into outer darkness, there shall be weeping and gnashing of teeth.

 14 For many are called, but few are chosen.
