From the GA website - The Committee on Civil Union and Marriage Issues voted Tuesday (34-18-2) to recommend to the full Assembly changing the definition of marriage in the Directory for Worship from “a woman and a man” to “two people.”
Heeding the advice of the Advisory Committee on the Constitution, the committee agreed to replace “couple” with “two people” because, according to Advisory Committee on the Constitution representative Catherine McDonald, “couple” in some languages “automatically translates as husband and wife.”
The committee also recommended approving an Authoritative Interpretation that gives ministers of the Word and Sacrament and commissioned lay pastors discretion over which marriage services they'll perform. Sessions may refuse the use of church property for wedding ceremonies of which they don’t approve.
An Authoritative Interpretation requires no approval by presbyteries and does not amend the church’s constitution. If it’s approved this week in plenary session, it becomes effective immediately.
