Questions still remain on how repealing the policy that banned gays serving openly in the military will be implemented.

The Senate voted Saturday to end the 17-year-old "Don't Ask, Don't Tell" policy and President Barack Obama is expected to sign the legislation, Wednesday.

Once signed, it will be up to the Pentagon to work out the details of how the ban will go into effect.

Still, several conservative Christians worry about the impact the repeal will have on chaplains serving in the military.  Some have predicted a repeal would prompt an exodus of chaplains from the military.

CBN News spoke with retired Army chaplain Gen. Douglas Lee. He's now in charge of screening and placing chaplains for a group of conservative Presbyterian and reformed denominations.  Click play to watch.

Officials with the Southern Baptist denomination have been especially vocal in their opposition to the repeal.

"Homosexual behavior cannot be normalized without rejecting God's moral standards," Richard Land, president of the Southern Baptist Ethics and Religious Liberty Commission, wrote President Obama in a personal letter Friday.

"We are saddened that this institution in which membership is a privilege not a right would break from a tradition of high moral conduct," he added.

Southern Baptist chaplains account for 448 of the country's 3,000 active-duty chaplains.

Military officials maintain that chaplains' First Amendment rights will be protected under the repeal.

"Service members will not be required to change their personal views and religious beliefs. They must, however, continue to respect and co-exist with others who may hold different views," Pentagon officials noted in a Nov. 30 review.
