BANGOR – The Unitarian Universalist Society of Bangor has called a Boulder, Colo., woman to be the Park Street church’s new minister.

The Rev. Mary Rebecca Gunn will replace interim pastor the Rev. J. Bradbury Mitchell of Brunswick, who is scheduled to deliver his final sermon on June 22. Gunn is to begin her ministerial duties on Aug. 1.

The congregation announced Gunn’s appointment in a press release issued earlier this month.

Gunn, 60, was one of three applicants for the position. She replaces the Rev. Elaine Peresluha, who served as the congregation’s minister from 2000 to 2006.

“She was really drawn to our congregation,” Gail Werrbach, a member of the search committee, told the congregation earlier this month.

The committee, she said, was drawn to Gunn’s honesty, genuineness and “deep interest in our spiritual progress.”

On her visit to the area, Gunn preached “Dwelling in Possibility,” suggesting that individuals can have a profound effect on reality by acting on what is possible, according to the press release. She challenged the congregation to consider what they want the church to become.

“The more we put ourselves in a great dream, the more we get back …” the minister said. “What is this congregation’s great dream?”

Gunn had a 20-year career in management and business before earning her master of divinity degree from Starr King School for the Ministry, a Unitarian Universalist seminary in Berkeley, Calif. She earned her undergraduate degree in political science from Utah State University in Logan, Utah, and a master’s degree in business administration from St. Mary’s College of California in Moraga, Calif.

She has served as interim pastor of the Unitarian Universalist Church of Boulder, Colo., and an internship at the First Unitarian Universalist Society of Albany, N.Y., in 2006 where she was ordained.

Unitarian Universalism, with roots in Christian Protestantism, is a theologically liberal denomination characterized by its support of a “free and responsible search for truth and meaning.” Members do not share a creed, but are unified by a shared search for spiritual growth. The sect uses a variety of religious and humanist sources and has a range of beliefs and practices.

The Bangor society, located at 120 Park St., was formed in 1995 with the consolidation of the First Universalist Society and the Independent Congregational Society, Unitarian, located at the corner of Union and First streets in Bangor.

The church has about 150 members and is active in social justice and community affairs. The congregation supports a number of religious affinity groups and provides religious education for adults and children.
