Yisra’el has a long history of forgetting what makes people “holy,” what makes them “clean” to approach the Presence of the Name. The LORD does that; the person doesn’t make himself or herself holy. It’s also often been lost that being declared tamé (“unclean”) doesn’t make one sinful or wicked either. Understanding the parable of “clean” and “unclean” is key to understanding Yeshua’s instructions on hand-washing in Mark 7 and Peter’s vision of unclean meats in Acts 10.
Yeshua’s frequently argued with the Pharisees over their emphasis on their man-made traditions over the plain word of scripture and how their man-made traditions were doing more to keep people away from God than bringing them into God’s embrace.
Even after Yeshua’s death and resurrection, these false ideas about the inherent holiness of the Jewish people and the inherent wickedness of the Gentiles was hindering God’s goal to lift up, bring near, make clean and declare holy believers from the nations in the same way Heaven does for the “native-born.”
