Paul was inspired, but he wanted books: http://www.thegospelcoalition.org/blogs/justintaylor/2015/04/17/paul-was-inspired-yet-he-wanted-timothy-to-bring-him-books-to-read/
A review of Dangerous Calling:
From a Reformed standpoint I did want the sacraments to be addressed in the book. One of the most fruitful areas of study for any minister is to study the doctrine of the sacraments. They are entirely absent from the book. Although I am to administer the sacraments, I am as part of Christ’s body ‘to feed on Christ in your heart by faith with thanksgiving’, and, in the words of the Westminster Larger Catechism, I am to ‘improve my baptism.’ Tripp has this wonderful line that ‘If Christ is the head then all of the rest is just body’. I just wish he had applied it to this area.
Levy might also have pressed forward on the issue of the use of the term ‘ministry.’ Rereading Bannerman, it is clear that in the context of Christianity, the word ‘ministry’ is best restricted to that pertaining to Word, sacrament and discipline. That keeps it connected to biblical qualifications, office-bearing, and accountability. The danger, of course, is that this could fuel the rise of a new priestly caste within the church, though that seems hardly the most pressing problem today. Rather, the failure to restrict the term has led to a democratic free-for-all where anybody doing anything for the church (i.e., anybody who professes to be a Christian) has a ministry. And when a word means everything in general, it means nothing in particular. Thus, the linguistic stage is set for the downplaying of word and sacrament. And when we name ‘ministries’ after ourselves, we surely point back to ourselves and not to the one in whose name we claim to minister.
