A prominent Christian legal group is urging Christians nationwide to pray as the U.S. Supreme Court gets ready to decide the legal definition of marriage, Baptist Press reports. The court will take up two separate cases March 26-27 -- a portion of the federal Defense of Marriage Act and California's Proposition 8 -- and will either affirm the traditional definition of marriage or redefine it to include same-sex couples. Alliance Defending Freedom (ADF), which has been heavily involved in defending the traditional definition of marriage, is in the midst of a "nine weeks of prayer for marriage" initiative that includes weekly downloadable printouts naming attorneys and Supreme Court justices for whom to pray. "They need your prayers like never before," said ADF's president and CEO, Alan Sears. "God's design and purpose for marriage does not change, no matter what today's politicians, activists or courts choose to accept." For more information about the prayer initiative, click here.
