Crossings Church announced Sunday it is moving forward in talks to open a satellite campus at First Christian Church’s iconic dome building in Oklahoma City, which has been under threat of demolition.

First Christian Church, with its distinctive white egg-shaped dome, was one of the city’s biggest churches when it opened at NW 36 and Walker Avenue in 1956, led by the popular pastor Bill Alexander. The property was put up for sale two years ago with a dwindling congregation still worshiping there.

The Rev. John Malget, senior pastor of First Christian Church, said the congregation voted Sunday morning to allow the church's board of directors to proceed with negotiations to sell the church to Crossings.

He said the church’s Sunday attendance fluctuates from 40 to 70 each week and about 100 people attended Easter services on Sunday.
