My abiding memory of today’s debate on Trident will be the sight of Labour MPs falling over each other to declare their enthusiasm for nuclear weapons, their support for the Tories’ policies and their opposition to their own leader.

Playground-style arguing saw at least one Tory MP suggesting that opponents of Trident need to “grow up”, as if a belief in using violence to resolve conflict were a sign of maturity. Meanwhile, Theresa May failed to answer one of the first hostile questions she has received from an MP since becoming Prime Minister (from Caroline Lucas) and stumbled through her answer when challenged by the SNP’s Angus Robertson about costs.

Today’s vote can hardly have been a surprise to anyone familiar with the childish antics and macho posturing that pass for democracy in the House of Commons. The question for opponents of Trident is: What do we now?

Last week, five major church denominations – the Baptist Union, the Church of Scotland, the Methodist Church, the Religious Society of Friends (Quakers) and the United Reformed Church – collectively urged MPs to reject nuclear weapons and vote against Trident renewal. This was excellent.

It will be even better if they will follow through on their principles and encourage peaceful struggles against Trident to continue by other means.

Parliament is only part of the process. We all share some responsibility for what our society does. Nobody has a right to prepare an act of mass murder. Today’s vote should make us determined to back nonviolent direct action for disarmament, whether in the case of nuclear weapons or others.

The churches’ voices would be stronger if they would vocally back nonviolent direct action, at least against Trident if not against militarism generally. Most of them maintain chaplains in the armed forces. What an impact it would make if they would declare that their chaplains will encourage troops to disobey orders if Trident is renewed.

While several Anglican and Roman Catholic bishops have, as individuals, criticised nuclear weapons, the Church of England as a whole has generally shied clear of lining up with other denominations to oppose it. Last year, however, a Church of England statement suggested that the arguments for Trident need “re-examining”.

I suppose this is progress of a sort. At least the Church of England is beginning tentatively to lean in the right direction. It’s also profoundly mistaken. The arguments do not need re-examining. They have been examined for years. We need to get beyond the call for debates and take up the all to action. Let’s get on with it.
