President Obama's traditional Father's Day proclamation was anything but traditional as he  saluted gay fathers in his annual declaration - a move that is believed to be a first in presidential history.

"Nurturing families come in many forms, and children may be raised by a father and mother, a single father, two fathers, a step-father, a grandfather, or caring guardian," the President declared. "For the character they build, the doors they open, and the love they provide over our lifetimes, all our fathers deserve our unending appreciation and admiration."

As the Washington Post noted, it may be the first time that gay fathers have been included in a presidential Father's Day proclamation.

"George W. Bush's final proclamation in 2008 noted the "extraordinary effort of the nation's fathers, stepfathers, grandfathers, and guardians," wrote Alec MacGillis of the Post. "And the furthest Obama's proclamation last year went in giving a nod to nontraditional fathering was to 'honor those surrogate fathers who raise, mentor, or care for someone else's child.''

The move has been heralded in pro-gay websites and blogs. "Obama includes gay dads in proclamation," proclaimed Advocate.com.  GLTNewsnow.com said President Obama was being "all inclusive."

"Glad you recognize that fathers, including gay fathers, not only carry enormous responsibilities, but often serve as mentors, tutors, and leaders within our neighborhoods and communities," wrote Michael Jones, an editor at Change.org.

The proclamation has not been well-received among Christian conservatives.

"The only two fathers in a home should be God and dad," said Michael Linton, pastor of Hope Fellowship in Humble, TX. "Unfortunately, it's an even more blatant (if possible) acceptance and endorsement of the homosexual lifestyle than we have previously seen from him."

"It should go without saying that same-sex parents are completely and totally unbiblical," Pastor Linton said. "But here we have the president endorsing a non-biblical, non-traditional, mostly unaccepted lifestyle by proclamation."

Southern Baptist pastor Mark Wood said conservatives should be upset. "Rightfully so, our country is slipping," he told FOX News Radio. "Even churches are tolerating the unthinkable. This is a prime example of loss of a standard - Bible."

But not all conservatives are taking issue with the president's proclamation -- including Mark Williams, a spokesman for Tea Party Express. "Any child fortunate enough to have two parents who love him or her, is blessed, especially in today's world," he said.
