The officers of the church are the elders and deacons as selected by the congregation.
   (Acts 6:2-7; I Peter 5:1-5; Phil. 1:1)

The ministers are called by the congregation to service.  They are servants of the church and are not called upon to be the official decision makers, or rulers, of a local congregation. 

So how do you become a Christian?  We want you to become a Christian the New Testament way.  Read the book of Acts which is filled with conversions.
