The group last month passed a resolution supportive of gay unions, and will hold a news conference Thursday. The same-sex marriage debate is expected to be a fierce one this year, and advocates on both sides of the issue are already planning events.

Opponents too are planning events, including a prayer day this Sunday opposing gay marriage.
