Scott's successor was John Burt, a friend of King and labor leader Cesar Chavez.
Staff member Anne Breck Peterson remembers the excitement in the stately church during the Vietnam era when antiwar songs jumped from the radio to Sunday's Rock Mass. Regas' stand against the Vietnam War drove some congregants away, she said: "George almost lost his job." But it also drew newcomers to the parish.
That pattern continues at All Saints today, with the church's controversial stands driving out some and drawing in others.
The activism attracted 22-year-old Stephanie Armitage, a teacher from Upland. "That's what I like about it," she said. "I think it is doing what the church should be doing."
But what Raymond Kreisel saw as "overt politicization and radicalization" in 2002 and 2003 led the Glendora resident and his wife, Amy, to leave All Saints.
Kreisel, 38, said he and his wife loved the church when they became active in 1995. They were married there in 1997, and the first of their two children, Liam, now 4, was baptized at All Saints.
Kreisel praised the church's "wonderful sense of community" and its architecture. In that hushed, incense-scented church, with the light streaming through the windows, "you feel like you're back in a mid-sized, 300-year-old church in England," he said.
But when Bacon began preaching against the coming war in Iraq, Kreisel, who then believed the war was justified, began to feel hectored.
"We were made to feel that if we weren't sharing his views, we weren't participating fully in the church," he said. "They weren't saying, 'Don't come to church.' But walls were being built, and we were in the out group."
For Amy Kreisel, the final straw was an e-mail from another member of the church's God, Mommy and Me group, asking if any of the other mothers wanted to start an "arrest co-op" to provide baby-sitting for children whose mothers might be arrested protesting the war.
The Kreisels felt that the church leadership was unresponsive to their letters and e-mails of concern. The couple stopped putting money in the collection plate, then found another Episcopal church to join.
But others say All Saints is tolerant of dissent, from whatever political or theological direction.
"You don't have to sign on to one particular orthodoxy at All Saints," said Senior Warden Long. "I don't know anyone who agrees with everything that is said at All Saints. That's what makes it such a great place to be. We agree to disagree."
Eddie Gibbs, 67, an Anglican priest and professor at Fuller Theological Seminary in Pasadena, said that "All Saints has a reputation for pushing the boundaries and seeking to say what it means for a church to be faithful to the Gospel in our present cultural context. They don't flinch at addressing pressing social issues.
"Other churches and Christian leaders may disagree with their positions and conclusions, but at least they are addressing the right questions," said Gibbs, adding that he is probably more conservative than many at All Saints.
People of faith should be asking themselves whether the Iraq war is justified, he said. All Saints provided an open forum for that discussion, he added, and "they shouldn't be penalized for that."
The church has launched initiatives for peace and justice and against poverty, political oppression in Central America, and AIDS. In 1989, All Saints declared itself a "a prayerfully pro-choice church."
All Saints has had female priests since 1978, and Lorentho Wooden became its first African American cleric in 1987.
Peterson said the staff talked about taking a stance on gays and lesbians "for about six years" before Regas announced in 1990 that he planned to start blessing "same-sex covenants" and preached a landmark sermon, "God, Sex, and Justice."
The first such blessing at All Saints in 1991 drew angry crowds to the doors of the church. It was an early example of the divisions over homosexuality that have riven both the Episcopal Church in the United States and the worldwide Anglican Communion to which it belongs.
Peterson remembers that the louder the anti-gay forces became, the more other people -- gay and straight -- approached the church, saying they sought an inclusive house of worship. And some congregants probably quietly moved elsewhere as well, church officials say.
Long said All Saints has allowed him to meet people who are intellectually curious, compassionate and deeply spiritual. And, he said, "it's just plain fun to be around the people in this parish."
He said he feels that All Saints has changed him for the better. He thinks he is less snobbish than he once was, less cliquish. Like many others at the church, the 60-year-old attorney speaks of his "faith journey."
"For the first time in my life," Long said, " I feel very comfortable with how I put my faith into action, and speak my faith to others, and live it and walk it."
