I answered that several times. Matthew 16 and Matthew 18 contain a reference to the judgment of the Church on Earth is binding in Heaven.
1 And there came to him the Pharisees and Sadducees tempting: and they asked him to shew them a sign from heaven.
2 But he answered and said to them: When it is evening, you say, It will be fair weather, for the sky is red.
3 And in the morning: To day there will be a storm, for the sky is red and lowering. You know then how to discern the face of the sky: and can you not know the signs of the times?
4 A wicked and adulterous generation seeketh after a sign: and a sign shall not be given it, but the sign of Jonas the prophet. And he left them, and went away.
5 And when his disciples were come over the water, they had forgotten to take bread.
6 Who said to them: Take heed and beware of the leaven of the Pharisees and Sadducees.
7 But they thought within themselves, saying: Because we have taken no bread.
8 And Jesus knowing it, said: Why do you think within yourselves, O ye of little faith, for that you have no bread?
9 Do you not yet understand, neither do you remember the five loaves among five thousand men, and how many baskets you took up?
10 Nor the seven loaves among four thousand men, and how many baskets you took up?
11 Why do you not understand that it was not concerning the bread I said to you: Beware of the leaven of the Pharisees and Sadducees?
12 Then they understood that he said not that they should beware of the leaven of bread, but of the doctrine of the Pharisees and Sadducees.
13 And Jesus came into the quarters of Caesarea Philippi: and he asked his disciples, saying: Whom do men say that the Son of man is?
14 But they said: Some John the Baptist, and other some Elias, and others Jeremias, or one of the prophets.
15 Jesus saith to them: But whom do you say that I am?
16 Simon Peter answered and said: Thou art Christ, the Son of the living God.
17 And Jesus answering, said to him: Blessed art thou, Simon Bar-Jona: because flesh and blood hath not revealed it to thee, but my Father who is in heaven.
18 And I say to 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 to thee the keys of the kingdom of heaven. And whatsoever thou shalt bind upon earth, it shall be bound also in heaven: and whatsoever thou shalt loose upon earth, it shall be loosed also in heaven.
20 Then he commanded his disciples, that they should tell no one that he was Jesus the Christ.
21 From that time Jesus began to shew to his disciples, that he must go to Jerusalem, and suffer many things from the ancients and scribes and chief priests, and be put to death, and the third day rise again.
22 And Peter taking him, began to rebuke him, saying: Lord, be it far from thee, this shall not be unto thee.
23 Who turning, said to Peter: Go behind me, Satan, thou art a scandal unto me: because thou savourest not the things that are of God, but the things that are of men.
24 Then Jesus said to his disciples: If any man will come after me, let him deny himself, and take up his cross, and follow me.
25 For he that will save his life, shall lose it: and he that shall lose his life for my sake, shall find it.
26 For what doth it profit a man, if he gain the whole world, and suffer the loss of his own soul? Or what exchange shall a man give for his soul?
27 For the Son of man shall come in the glory of his Father with his angels: and then will he render to every man according to his works.
28 Amen I say to you, there are some of them that stand here, that shall not taste death, till they see the Son of man coming in his kingdom.
Matthew 18
1 At that hour the disciples came to Jesus, saying: Who thinkest thou is the greater in the kingdom of heaven?
2 And Jesus calling unto him a little child, set him in the midst of them,
3 And said: Amen I say to you, unless you be converted, and become as little children, you shall not enter into the kingdom of heaven.
4 Whosoever therefore shall humble himself as this little child, he is the greater in the kingdom of heaven.
5 And he that shall receive one such little child in my name, receiveth me.
6 But he that shall scandalize one of these little ones that believe in me, it were better for him that a millstone should be hanged about his neck, and that he should be drowned in the depth of the sea.
7 Woe to the world because of scandals. For it must needs be that scandals come: but nevertheless woe to that man by whom the scandal cometh.
8 And if thy hand, or thy foot scandalize thee, cut it off, and cast it from thee. It is better for thee to go into life maimed or lame, than having two hands or two feet, to be cast into everlasting fire.
9 And if thy eye scandalize thee, pluck it out, and cast it from thee. It is better for thee having one eye to enter into life, than having two eyes to be cast into hell fire.
10 See that you despise not one of these little ones: for I say to you, that their angels in heaven always see the face of my Father who is in heaven.
11 For the Son of man is come to save that which was lost.
12 What think you? If a man have an hundred sheep, and one of them should go astray: doth he not leave the ninety-nine in the mountains, and go to seek that which is gone astray?
13 And if it so be that he find it: Amen I say to you, he rejoiceth more for that, than for the ninety-nine that went not astray.
14 Even so it is not the will of your Father, who is in heaven, that one of these little ones should perish.
15 But if thy brother shall offend against thee, go, and rebuke him between thee and him alone. If he shall hear thee, thou shalt gain thy brother.
16 And if he will not hear thee, take with thee one or two more: that in the mouth of two or three witnesses every word may stand.
17 And if he will not hear them: tell the church. And if he will not hear the church, let him be to thee as the heathen and publican.
18 Amen I say to you, whatsoever you shall bind upon earth, shall be bound also in heaven; and whatsoever you shall loose upon earth, shall be loosed also in heaven.
19 Again I say to you, that if two of you shall consent upon earth, concerning any thing whatsoever they shall ask, it shall be done to them by my Father who is in heaven.
20 For where there are two or three gathered together in my name, there am I in the midst of them.
21 Then came Peter unto him and said: Lord, how often shall my brother offend against me, and I forgive him? till seven times?
22 Jesus saith to him: I say not to thee, till seven times; but till seventy times seven times.
23 Therefore is the kingdom of heaven likened to a king, who would take an account of his servants.
24 And when he had begun to take the account, one was brought to him, that owed him ten thousand talents.
25 And as he had not wherewith to pay it, his lord commanded that he should be sold, and his wife and children and all that he had, and payment to be made.
26 But that servant falling down, besought him, saying: Have patience with me, and I will pay thee all.
27 And the lord of that servant being moved with pity, let him go and forgave him the debt.
28 But when that servant was gone out, he found one of his fellow servants that owed him an hundred pence: and laying hold of him, throttled him, saying: Pay what thou owest.
29 And his fellow servant falling down, besought him, saying: Have patience with me, and I will pay thee all.
30 And he would not: but went and cast him into prison, till he paid the debt.
31 Now his fellow servants seeing what was done, were very much grieved, and they came and told their lord all that was done.
32 Then his lord called him; and said to him: Thou wicked servant, I forgave thee all the debt, because thou besoughtest me:
33 Shouldst not thou then have had compassion also on thy fellow servant, even as I had compassion on thee?
34 And his lord being angry, delivered him to the torturers until he paid all the debt.
35 So also shall my heavenly Father do to you, if you forgive not every one his brother from your hearts.
No it doesn't. The Catholic Church has one more time twisted the meaning of that text. Here is Young's literal translation of that verse.
Matthew 16:19 and I will give to thee the keys of the reign of the heavens, and whatever thou mayest bind upon the earth shall be having been bound in the heavens, and whatever thou mayest loose upon the earth shall be having been loosed in the heavens.
The disciples were being told to declare what has been bound in heaven. They were NOT being given licence to obligate heaven or God in any way only that they may tell the people what has been bound in heaven. The keys to the Kingdom was the gospel as recorded in scripture which when preached opens the Kingdom to those hearing.
