Armed with a new $400,000 grant and the support of the Episcopal Church, a Berkeley seminary is convening priests from across the country to craft the liturgical rite for same-sex couples to receive religious blessings. The new rite, which will take years to complete, will most likely consist of a series of original prayers, Bible readings and two essays: one on the theological meaning of same-sex blessings, and one advising priests who administer the new rite. If approved, the new blessing would be just the third addition to Episcopal liturgy since 1979.
