I don't think he's saying that Christians shouldn't take a stand on certain issues. Rather, I think he's saying that we shouldn't write our positions into law. The law cannot save. It may keep men from murdering, but it cannot keep them from murdering their brothers in their hearts. Only grace can do that. Additionally, he seems to think that there is an overemphasis on taking a stand with respect to certain issues and not others.
Please bear with me as I am going to disagree with you a bit here.
Christians are still citizens of the political entitity in which they reside are have an equal responsibility to participate in policy debate. I agree that the law can't save anyone's soul but the law can cause or prevent plenty of misery and pain.
Christians should not take the position that gay marriage should not be legally recognized because the Bible calls it a sin, this reasoning would indeed be writing spirituality into law. However, every sin (and I mean every sin) has real life consequences to it. God does not want us to sin in part because he loves us and does not want us hurting ourselves and others. I firmly believe that it is the responsibility of Christians to identify the real life consequences of sin and fight for public policy that appropriately takes those consequences into account.
As far as there being an overemphasis on certain issues and not others I agree that that is the case. However, a serious amount of scholarship has provided some pretty strong evidence that the public sphere can only deal with a limited amount of issue conflicts at any given time, so this will always be the case (see for example E.E. Schattsneider's "Semi Soveriegn People").
Before the sexual revolution the issues that are being overemphasized today were practically ignored, even by churches. At the turn of the 20th century the big issues were all about economic equality and many churches and ministers were actively involved policy fights (William Jennings Brian was their champion then).
The struggle in many churches is that there is a natural tendency to be used as community centers. This is problematic becuase although it seems so positive for the church to benifit the community as part of its witness, the church inevitably becomes embrioled in affairs of the community, which has a tendency to distract from its primary mission to share the good news of Christ and support spiritual growth. This is quite evident in urban chruches that get involved with ministries to the poor, which is a good thing and a good ministry, then end up embroiled in welfare and economic justice public policy issues.
This post was longer then I anticipated it was going to be and for that I apologize.
