One of the most frustrating things about the ‘occasional’ (rather than systematic) nature of the NT writings is that none of them give us precise details of what the first followers of Jesus did when they met together for ‘worship’. (I use inverted commas here, because the NT never actually uses the word ‘worship’ for what Christians did when they met.) If only Paul had attached to his letter to Corinth and order of service! We would have avoided centuries of debate between denominations, and saved ourselves hundreds of thousands of hours in liturgical revision—and even avoided the debate about whether we do in fact meet to ‘worship’!
The latest Grove Worship booklet is by Colin Buchanan, and asks the intriguing question: suppose we do have hints in the Letter to the Hebrews as to what happened when believers gathered? Colin is well equipped to ask this, being not only a life-long commentator and contributor to thinking about worship and liturgy in the Church of England, but also classically trained and an excellent exegete.
