On Monday, America will pause to honor the life of Dr. Martin Luther King, Jr., who would have been 82 years old on Jan. 15.
King's legacy of peace and purpose stands in contrast to the senseless violence brought by Jared Loughner, the suspected Tucson, Ariz., shooter.
Both subjects came up at church services attended by President Barack Obama and Attorney General Eric Holder Sunday.
The Obamas have only attended church in Washington, D.C., four times, preferring the privacy of the Camp David chapel. On Sunday, they chose to attend the Metropolitan African Methodist Episcopal Church which is located only six blocks from the White House.
During his sermon, Rev. Marie Braxton praised President Obama's speech delivered last week in Tucson during a memorial service. He also paid tribute to Martin Luther King.
First Lady Michelle Obama also received special recognition during the church service. The congregation took the time to sing "Happy Birthday" to her. She turned 47 on Monday.
At the Ebenezer Baptist Church in Atlanta, Ga., U.S. Attorney General Eric Holder spoke about Tucson and King.
"Last week a senseless rampage in Tucson, Arizona, reminded us that more than 40 years after Dr. King's own tragic death, our long struggle to end suffering, to eradicate violence and to promote peace -- that struggle goes on," Holder said.
In Houston, Texas, young people in more than 45 bands and youth groups marched in an annual parade to honor King.
Also, in Tucson, young and old alike gathered to stand against violence in what they called "The Walk for Peace."
