Greg Boyd is an author and pastor whom I much admire. I have really enjoyed reading his perspective on open theism and the warfare motif of scripture. I recently discovered his blog with which I was impressed by the range of topics under discussion. However, I do wish to pick a bone with Boyd's own theological position on vegetarianism.
First of all, I have no objection whatsoever to anyone becoming a vegetarian for ethical, cultural, or dietary reasons. Boyd even tells us that "God told him" to stop eating meat, and I have no beef with that at all. However I do wish to warm-heartedly push back on Boyd's assertion that Christians should seriously consider becoming vegetarians because in the New Creation we will only eat vegetables (and therefore we should anticipate that and prophetically embody that now).
The first thing that comes to mind is Isaiah:
The Lord who commands armies will hold a banquet for all the nations on this mountain. At this banquet there will be plenty of meat and aged wine – tender meat and choicest wine.
-- Isa 25:6 (NET)
So it seems the the Lord himself will serving prime steak and vintage red wine in the New Creation. If its good enough for God, its good enough for me. The only way we can get round this is to argue that it won't be real meat, which is surely the same as arguing that the wine at the Lord's banquet, or indeed the water that Jesus turned into wine, isn't alcoholic. Which is so brain-dead I can't even be bothered to waste my time to argue with! Face it, God knew in advance that one of life's most pleasurable experiences is eating a medium-rare steak with a glass of fine vintage wine in good company. :-)
(As a footnote, I am completely for animal welfare, I am appalled at the Western food industry, and I do my very best to ensure that all my meat, fish and dairy products I consume are either organically farmed or wild. I also sure that such standards are still below the Lord's, and that Christians should be at the forefront of the organic and fair-trade movements, pushing standards onward and upwards. A heavenly ethic on meat is not to abolish it but to kindly subdue and rule over animal creation.)
