Acts of the Apostles 8:9, 13-25.
Now a certain man named Simon had previously practised magic in the city and amazed the people of Samaria, saying that he was someone great. Even Simon himself believed. After being baptized, he stayed constantly with Philip and was amazed when he saw the signs and great miracles that took place. Now when the apostles at Jerusalem heard that Samaria had accepted the word of God, they sent Peter and John to them. The two went down and prayed for them that they might receive the Holy Spirit (for as yet the Spirit had not come upon any of them; they had only been baptized in the name of the Lord Jesus). Then Peter and John laid their hands on them, and they received the Holy Spirit. Now when Simon saw that the Spirit was given through the laying on of the apostles’ hands, he offered them money, saying, ‘Give me also this power so that anyone on whom I lay my hands may receive the Holy Spirit.’ But Peter said to him, ‘May your silver perish with you, because you thought you could obtain God’s gift with money! You have no part or share in this, for your heart is not right before God. Repent therefore of this wickedness of yours, and pray to the Lord that, if possible, the intent of your heart may be forgiven you. For I see that you are in the gall of bitterness and the chains of wickedness.’ Simon answered, ‘Pray for me to the Lord, that nothing of what you have said may happen to me.’ Now after Peter and John had testified and spoken the word of the Lord, they returned to Jerusalem, proclaiming the good news to many villages of the Samaritans.
Holy Gospel of Jesus Christ according to Saint Matthew 18:15-20.
‘If another member of the church sins against you, go and point out the fault when the two of you are alone. If the member listens to you, you have regained that one. But if you are not listened to, take one or two others along with you, so that every word may be confirmed by the evidence of two or three witnesses. If the member refuses to listen to them, tell it to the church; and if the offender refuses to listen even to the church, let such a one be to you as a Gentile and 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, if two of you agree on earth about anything you ask, it will be done for you by my Father in heaven. For where two or three are gathered in my name, I am there among them.’
