Lay preaching varies in importance between religions and their sects.
For example, the Unitarian Universalist Association reserves the title of "the reverend" for ordained ministers.
[1] The United Methodist Church authorized the role of "certified lay minister" (CLM) at its 2004 General Conference as a non-clergy leadership role, stating that CLMs should not use the title of "pastor"; be addressed as "reverend"; or wear clerical garb (i.e., the robe, stole or collar).
[2] Lay ecclesial ministry is a similar practice in the Catholic Church.
Lay ecclesial ministers serve the church in many ways, assisting priests, but are not ordained.
