Dave Strain is a Free Church of Scotland minister in London. (I think there are two Free Church congregations in the city, so I'm guessing that Dave is not on his own.) Dave is a great guy, an artist, a theological thinker, and a man with a passion for mission and evangelism in cultural context. Although I don't know him very well, I did enjoy and benefit from his friendship while he was in Glasgow a few years back. I sometimes seek his advice on stuff that ministers and student ministers need help with now and again.
Dave is a progressive thinker - check out this post, where he describes his view of a church service. I believe one of the things Dave is trying to do is recover a high liturgical tradition in line with the 16thC Reformed (and Lutheran, perhaps?) orders of worship (this includes responses to prayers, vocal confession of faith, vocal confession of sin using a set text, etc).
Exciting stuff, indeed. I was given a taste of this kind of worship when Sinclair Ferguson was minister of St George's Tron, in Glasgow. I became aware of the opportunity that liturgy provided for safeguarding evangelical truth, while at the same time enriching Presbyterian worship experience. Quite frankly, bare hymn sandwich services, with the emphasis on children's addresses and sermons, are just not good enough. The people of God deserve more. I don't know if Dave has any sympathy for the emerging church movement - but, it strikes me that this kind of recovery of Reformed 16thC worship is essentially one expression of the emerging church movement - people are finding all sorts of ways to express their disgust at the poverty of so much that passed for worship in the modern (1700-1950?) era.
So, perhaps my dilemma of similarity thesis doesn't quite cover all church traditions or denominations - but it certainly can be applied within traditions or denominations - and, reading between the lines of his post, I think Dave might just agree.
