Is there a legitimate contextual comparison between what Jesus teaches in Matthew 18:15-20 (certain disciplinary functions working in an assembly of people in God's name) and the text in John 20:21-23? (That is, are both texts referring to the same subject matter?)
I ask this question because it seems that Jesus may be "handing over the baton" to his disciples in John 20, so to speak, as He was soon to ascend to the father as read in Acts 1.
Here are the scriptures in question.
“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." (Matt 18:15-20 NASB)
So Jesus said to them again, "Peace be with you; as the Father has sent Me, I also send you." And when He had said this, He breathed on them and said to them, "Receive the Holy Spirit. If you forgive the sins of any, their sins have been forgiven them; if you retain the sins of any, they have been retained." (Jn 20:21-23 NASB)
