The ushering department is responsible for ushering members of the congregation into designated areas assigned for them. They are usually very alert and strategically placed around the aisles during church services to ensure they attend to the needs of the congregation effectively and efficiently with very minimal disruption to the service.
This is the group that shows kindness in welcoming members and guests to church. The ushers are charged with maintaining orderliness in services and keeping the Church in a decent and presentable condition.
Not forsaking the assembling of ourselves together, as is the manner of some, but exhorting
one another, and so much the more as you see the Day approaching.
Hebrews 10:25 [NKJV]
