What is an Evangelical?
Evangelical (Greek euangelos, good tidings; gospel)
This term was originally claimed as a right by all Protestants, in that their beliefs were derived entirely from the Bible. In the course of time, however, its use and meaning have varied greatly. It has been especially applied to the school which insists on the utter depravity of unregenerate human nature, necessity for conversion, justification of sinners by faith, free offer of the gospel to all mankind, and the divine inspiration, authority, and sufficiency of Holy Scripture (reserving the right of individual believers to interpret scriptural passages according to their judgment). In the Anglican Communion, holders of such beliefs are usually known as 'Low Church'. In Germany the word applies to Lutherans, or to the United Church as combining Lutheran and Reformed churches, but it is also sometimes assumed by the pietistic party within the Protestant Church.
Evangelist (a bringer of good tidings, preacher of the gospel),
In the New Testament, an evangelist was an official of the Christian Church, whose chief duties seem to have been those of a missionary and pioneer. The evangelist is not permanently connected with any local field of work, or employed in the regular ministry; his work is of an itinerant rather than a local nature. Thus Philip of Caesarea and Timothy of Ephesus are called evangelists. The term was also used in post-apostolic times for those who read and explained the written gospels in public worship; but it is more often used today in its earlier sense and has been transferred to the writers of the four gospels.
