The Southern Baptist Convention (SBC) has barred its military chaplains from performing, attending or supporting weddings for gay and lesbian couples.

The North American Mission Board (NAMB), an arm of the SBC, released the guidelines last week in response to the Department of Defense's recent decision to recognize such marriages and extend benefits to the spouses of gay servicemembers, the AP reported.

Chaplains are also prohibited from offering “any kind of relationship training or retreat, on or off of a military installation, that would give the appearance of accepting the homosexual lifestyle or sexual wrongdoing.”

The Tennessee-based SBC provides the largest share of active-duty military chaplains.

Doug Carver, a retired Army major general and executive director of NAMB's Evangelism Group, said in an accompanying statement that SBC chaplains “want to uphold the authority and relevancy of Scripture while continuing to serve in a very diverse setting.”

Chaplains are also not to “lead or participate in a worship service” with a chaplain, volunteer or contractor who “personally practices or affirms a homosexual lifestyle or such conduct.”
