Consider Matthew 11:16-19;8:1-4;Luke 7:36-50 and see the below.

Priestly Prophetic
1 Purity 1 Justice
2 Sin was something that was seen as contagious 2 Taking action against sin
3 Separation from anything or anyone who would make them unclean 3 Righting social wrongs in Israel
4 Holiness by separation and/or distance 4 Holiness by action

Does God want us to be pure or just? Yes

Real purity contaminates impurity; real holiness contaminates sin.

Jesus was a friend of sinners.

Lepers were seen as unclean or outcasts.

Is the Parable of the Good Samaritan about being unclean or about helping another in need?
