How is the kingdom of heaven closed and opened by Christian discipline?
Matthew 18:15-20 – “If your brother or sister sins, go and point out their fault, just between the two of you. If they listen to you, you have won them over. But if they will not listen, take one or two others along, so that ‘every matter may be established by the testimony of two or three witnesses.’ If they still refuse to listen, tell it to the church; and if they refuse to listen even to the church, treat them as you would a pagan or a tax collector.
“Truly I tell you, whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.
“Again, truly I tell you that if two of you on earth agree about anything they ask for, it will be done for them by my Father in heaven. For where two or three gather in my name, there am I with them.”
1 Corinthians 5:3-5 – For my part, even though I am not physically present, I am with you in spirit. As one who is present with you in this way, I have already passed judgment in the name of our Lord Jesus on the one who has been doing this. So when you are assembled and I am with you in spirit, and the power of our Lord Jesus is present, hand this man over to Satan for the destruction of the flesh, so that his spirit may be saved on the day of the Lord.
1 Corinthians 5:11-13 – But now I am writing to you that you must not associate with anyone who claims to be a brother or sister but is sexually immoral or greedy, an idolater or slanderer, a drunkard or swindler. Do not even eat with such people.
What business is it of mine to judge those outside the church? Are you not to judge those inside? God will judge those outside. “Expel the wicked person from among you.”
2 Thessalonians 3:14-15 – Take special note of anyone who does not obey our instruction in this letter. Do not associate with them, in order that they may feel ashamed. Yet do not regard them as an enemy, but warn them as you would a fellow believer.
Luke 15:20-24 – So he got up and went to his father.
“But while he was still a long way off, his father saw him and was filled with compassion for him; he ran to his son, threw his arms around him and kissed him.
“The son said to him, ‘Father, I have sinned against heaven and against you. I am no longer worthy to be called your son.’
“But the father said to his servants, ‘Quick! Bring the best robe and put it on him. Put a ring on his finger and sandals on his feet. Bring the fattened calf and kill it. Let’s have a feast and celebrate. For this son of mine was dead and is alive again; he was lost and is found.’ So they began to celebrate.
2 Corinthians 2:6-11 – The punishment inflicted on him by the majority is sufficient. Now instead, you ought to forgive and comfort him, so that he will not be overwhelmed by excessive sorrow. I urge you, therefore, to reaffirm your love for him. Another reason I wrote you was to see if you would stand the test and be obedient in everything. Anyone you forgive, I also forgive. And what I have forgiven—if there was anything to forgive—I have forgiven in the sight of Christ for your sake, in order that Satan might not outwit us. For we are not unaware of his schemes.
