Class Leaders have always been a very significant component of the St. Mark ministry. The record of the Board of Class Leaders from the earliest days of the church documents the dedicated activity of the class leaders to support the spiritual and temporal well-being of the members of the church.

The Board of Class Leaders is made up of class leaders and the assistant class leader. In St. Mark, the pastor has assigned an assistant class leader for every leader. The class leader is a role that is special in Methodism. The role of the class leader is to encourage their class members to be faithful disciples. Class leaders visit with their members during sickness or life crises when the members need support. They are helping for encouraging members to feel connected with the church fellowship. Many people remark how their class leader helped them in their faith development and to stay faithful to the church.
