ST. LOUIS — At worship services around this region, clergy on Sunday called for recovery and healing after a week that began with an announcement that a grand jury would not indict a white police officer who shot an unarmed black teenager in Ferguson and that then careened through looting, fires, and tense standoffs with the police and National Guard soldiers.

Yet in many of the messages, there were also calls to continue a movement raising questions about race and police behavior that followed the shooting of 18-year-old Michael Brown. That momentum and those concerns, some clergy members said, should not be allowed to fade away or be forgotten.

“I’m tired of living a certain way in our city,” the Rev. Shaun Ellison Jones, the assistant pastor of Mount Zion Baptist Church-Christian Complex here, told the mostly black congregation in a simple room with tile floors. “I’m tired of some unjust laws.”

“As Christians, our church encourages us to be engaged in the life of the city, the life of our community,” Mr. Jones said. He urged congregants to ride a chartered bus to Jefferson City, the state capital, on the first day of the legislative session in January to make their views known.
