Kevin DeYoung addresses why gay marriage has become popular with young people. He also tells us what Christians can do about it. As usual, a lot of wisdom and balance in this post.
Carl Trueman explains how the church’s compromise with gay marriage began with our acceptance of no-fault divorces.

It began when we decided the sexual relationship was primarily about personal pleasure and not about children.
Here is a longer, more difficult article by Robin Phillips on gay marriage and its implications for traditional marriage. It is heady, but good.
Finally, here is an article by Tim Bayly on why he uses the word sodomy instead of gay or homosexual.
