Formal doctrine and list of duties of our being members of the Priesthood of All Believers according to the latest Reformed theology

Other questions have covered: - [Biblical basis and our duties](https://christianity.stackexchange.com/a/48414/10672) of being priest - How being members of this royal priesthood of all believers is [different than specific roles in a church](https://christianity.stackexchange.com/a/23627/10672) My question is: What is the mature 21st century Reformed theology on: 1. WHAT our duties are TODAY as priests in the [Priesthood of all Believers](https://en.wikipedia.org/wiki/Priesthood_of_all_believers) , and 1. Complete DOCTRINE that cover *all* relevant OT and NT verses interpreted from Reformed perspective, which needs to cover: - Specific Reformed-style typology from OT priesthood - Formal definition of New Covenant "priest" and how it is considered "exclusionary" compared to the "inclusionary" Catholic version - How this priesthood is contrasted to the roles mentioned in the New Testament (largely covered already in the 2nd question linked above) - Identifying what our duties are *now* vs. *future* (after the second coming) - *Practical priestly significance* (to others) of having direct access to God - Relationship to *spiritual gifts* - New Testament equivalent of offering *spiritual* sacrifices - Implications of the *meaning of worship*, whether individually or corporately (since worship WAS part of temple priestly function) - Prophetic and teaching roles to announce Jesus to the unconverted world - Being agents of reconciliation to the world - Relationship to our other duties to be disciples of Christ, etc. - How are we to be stewards of creation, thus recovering Adam's original calling - Etc. Resources in the first linked question (such as [this](https://web.archive.org/web/20160427191009/https://ifwe.s3.amazonaws.com/wp-content/uploads/2013/10/Priesthood-of-All-Believers_Final.pdf)) already have the kernel of an answer but it is not specific to Reformed theology. I'm also asking for a formal definition such as what one would read out of a 21st Reformed Systematic Theology book that has taken into account new Biblical research for better understanding of Second Temple Judaism. Thus, **citations** from those kinds of books (or a journal paper equivalent) would be expected in an answer. Some resources that can be consulted by an answer: - A 2021 *Christianity Today* article [5 Books that Portray the Priesthood of All Believers](https://www.christianitytoday.com/2021/09/5-books-priesthood-of-all-believers-cliff-warner/) (not specific to Reformed theology, though)
