I have an article up at Reformation 21 on the identity of those who do the work of gospel ministry: pastors. Here’s an excerpt,

God’s gracious, redemptive covenant has been administered in different ways to his people throughout history. All of these ways in the Old Testament, circumcision, the Paschal meal, the Mosaic sacrifices, prefigured Christ, and were shadows anticipating him who is the substance of God’s grace. This is what Paul means in 2 Corinthians 3:7-11 and Colossians 2:17, and what is taught in Hebrews 8 when the Mosaic sacrifices, described as copies and shadows of Christ, are contrasted with the better leitourgia (ministry) obtained by Christ in the new covenant. Jesus is the leitergous (liturgist!), the administrator or server, of the new covenant (Hebrews 8:2) of which he is the substance. In other words, in the new covenant, gospel ministry is Jesus serving himself to his people.

This article is the probably the best biblical summary of my theology of my ministry.
