A template is the webpage front end functionality of the wordpress content management system framework.
There are thousands of responsive wordpress template designs online to search out and choose from. I know that your Church is a unique part of a larger body and your church has its own personality that reflects its many members and the mission that the Lord has imparted to it. So your webpage needs to be an extension of your churches mission statement. It needs to express the uniqueness of your Church body in both content and visual appearance.
This is why I have prepared a list of Church website templates and WordPress theme resources for you to use to search and investigate for the template that will best fit the Church God is leading you to grow.
