It was this corrupted system of traditions that Christ vehemently denounced. With this system of oral traditions, they corrupted and manipulated the people. This verse mentions six types of people who cannot enter the Kingdom of God. It is used metaphorically to identify those who pervert the gospel, and there are many within Israel who pervert the gospel. They teach that we, as racial Israelites, are so much holier than the other races that entrance into the city is automatic.
Caution is Warranted Here.
Think about what is being said in this verse. Of course there are. We need to consider in a broader sense what the Scripture is telling us here. Those who pervert the Gospel will not be allowed to enter into the city. These perverters of the Gospel are those who live unrighteously and uphold unrighteousness.
