VATICAN CITY -- Pope Benedict XVI on Friday denounced the "powerful political and cultural currents" that are working to "alter the legal definition of marriage" in the United States.
The pope's condemnation of same-sex marriage came in an address to a delegation of bishops from Minnesota, North Dakota and South Dakota, headed by Archbishop John Nienstedt of St. Paul and Minneapolis.
Maryland legalized gay marriage March 1 and Minnesota will be one of five states to vote on the issue in the coming months. Minnesota's bishops are campaigning for a constitutional amendment to ban same-sex marriage.
Benedict stressed that "sexual difference cannot be dismissed as irrelevant to the definition of marriage," and called on the church to continue its "reasoned defense of marriage."
The pope also echoed bishops' concerns over their battle with the Obama administration on the contraception mandate. "Threats to freedom of conscience, religion and worship" in the United States, he said, "need to be addressed urgently."
