First, I do want to note that the parallel between pastor and priest is, perhaps, not that parallel, but nonetheless, there is something important here to note.
As I meet pastors and get acquainted with ministries, I note something that bothers me. Also note that I'm opinionated and getting more so yearly.
I just hope my opinions are formed by Scripture. I'm seeking to make sure that is the case.
However, the job in Leviticus 10, among others, was for the priest to "distinguish" between the holy and the common, and between the unclean and the clean..." and "to teach the people of Israel all the statutes that the LORD has spoken to them by Moses."
Now I do believe inherent in this is NOT just lists of clean and unclean. The LORD says in Psalm 50 that right sacrifices are thanksgiving and that he does not need goats and bulls.
Somehow I don't think the heart of the job was teaching the list, but teaching the character of God that makes a distinction between who is holy and who is not. The point was God, not that people performed properly.
2 Chronicles 30 is an example of how the people were not clean, Hezekiah prayed for them, and the LORD healed the people although not clean by the law's standard. The point is that God is holy, they are not, and HE is the one who makes them clean, not their list keeping.
Why then so many pastor/teachers focus on pragmatism? Why do we teach "how to" without first teaching "who"?
Will "how to" make more sense if we know "who" and "why"? I think so.
I believe we create list keeping people who do not know God if we give them solutions to their problems without giving them the solution to their evil hearts, namely, Jesus. To help solve their problems without giving them the ultimate solution, the knowledge of God in Christ Jesus, is like putting a band aid on a broken leg. It does not ultimately help.
