Just saw this on NY Times website: Supreme Court to Take Up Gay Marriage 
WASHINGTON — The Supreme Court announced on Friday that it would enter the national debate over same-sex marriage, agreeing to hear a pair of cases challenging state and federal laws that define marriage to include only unions of a man and a woman.
Decisions in all of those cases are expected by June.
In response, the U.S. bishops' conference issued a statement from Archbishop Salvatore Cordileone of San Francisco, chairman of the bishops’ Subcommittee for the Promotion and Defense of Marriage.
“The U.S. Supreme Court’s decision to hear these cases is a significant moment for our nation,” Cordileone said. “I pray the Court will affirm the fact that the institution of marriage, which is as old as humanity and written in our very nature, is the union of one man and one woman. Marriage is the foundation of a just society, as it protects the most vulnerable among us, children. It is the only institution that unites children with their mothers and fathers together. We pray for the Court, that its deliberations may be guided by truth and justice so as to uphold marriage’s true meaning and purpose.”
