The Holier-Than-Thou-Congregation (HTTC) is very similar, or perhaps the exact same, as what Jesus calls the "synagogue of Satan" in Revelation 2:9.
You can find many references to them throughout Jesus' teaching in the four gospels. One such parable can be found in Luke 18:9-14.
Here is another parable where the minor characters are members of the HTTC, but the protagonist and hero is of a despised people-group, this parable is best known as "The Good Samaritan," found in Luke 10:25-37.
Even though many of the HTTC judge by outward appearances and consider you blessed by God if you are dressed very well, and cursed scum if you do not, some members of the HTTC hold the opposite opinion, if you dress nicely then you are a rich scum-bag jerk. But the bottom line for both extremes is they do not have the love of God in their hearts. [John 5:42]
The HTTC are experts at announcing their good deeds. [Matthew 6:1-7] They worry greatly when someone disparages them. [Matthew 5:11-12, Luke 6:22] And are working over-time to fulfill the prophecies of Jesus, like making sure the sinners, prostitutes, and the like get in to heaven before they do. [Matthew 21:28-32]
