I read in a post on the board today a snip of this passage, "where two or three are gathered in my name". This is one of the most misapplied portions of scripture in the entire bible. It is often used to say that where two are three are gathered [in prayer], God is in the midst. If that was true than God would not be present if one or four are gathered in His name. The passage has nothing to do with the gathering of the church/believers for worship, prayer, or fellowship. The passage is referring specifically, and exclusively, to church discipline. Jesus is explaining how to deal with a brother who sins. He goes through the process of showing the brother his fault in private. If the brother refuses to repent the process is escalated, all they way up to, and including, excommunication. Jesus underscores the need for truthful witnesses in the process, so He states that charges need to be confirmed by two or three witnesses (v. 16). He repeats Himself in verse 19 by saying, "Again, I say to you...". Now, it is true that Jesus is present, through the Holy Spirit, if two or three are gathered. But He is also present if one, twelve, or three hundred and eighty five are gathered.
