Note: This post is third in a series of posts about what we can learn from the Supreme Court’s June 2013 DOMA decision, and how that can help us better promote and defend marriage. This series is based on a July 2013 talk by staff of the USCCB Subcommittee for the Promotion and Defense of Marriage.
