What is planned for Easter Sunday? Why is this important? What psychological value does it offer?

From the text:

An interdenominational Easter Sunrise Service will be held in Marines Park on Sunday, April 17th. All citizens of Fort Repose, of whatever faith, are invited to attend. Signed,

 Rev. John Carlin, First Methodist Church Rev. M. F. Kenny, Church of St. Paul's Rev. Fred Born, Timucuan Baptist Church Rev. Noble Watts, Afro-Repose Baptist Church

The church service offers hope and gives people something to believe in. Those who have faith will have the ability to share their faith.
