The term 'Church CENTER' is composed of two words, 'NAVE' and 'CENTER'. NAVE is a four-letter word which refers to the central part of a church, typically in the shape of a cross. It is usually the longest part of the church and is where the congregation sits. The CENTER of the church is the area around the altar, which is the focal point of the church. This is where the priest or minister stands to lead the service.
