Given these complexities, many prefer terms like "missionary" or "church planter" to describe those sent to advance the Gospel amongst new peoples and places. However, I believe there is a case to be made for the continued use of the word "apostle" primarily on the basis that it is a biblical term used to describe those in the Bible who were sent out to establish churches and advocate their continual maturing process.
