Tragedy in Charleston, S.C., brought about a spirit of unity in Houston as clergy from several faith groups joined together Saturday to remember nine men and women who were slain Wednesday during Bible study at Emanuel African Methodist Episcopal Church. M.J. Kahn, president of the Islamic Society of Greater Houston, said the massacre of religious worshippers in South Carolina affects everyone, regardless of their creed. Bishop Michael Rinehart of the Evangelical Lutheran Church in America said he has more questions than answers about what happened and, at first, had no great desire to speak at the vigil. The congregation clapped along, with members standing up and shouting "Amen" as the spirit hit them. Civic leaders also offered their thoughts and prayers about the massacre and the need for people of faith to stand together.
