Readers of this blog probably already know the definition of an "evangelical Christian," but in case not, Justyn Terry, Dean and President of Trinity School for Ministry in Ambridge, PA, offers an excellent, clarifying understanding:
The word "evangelical" is used in many different ways these days, and there is much debate about its meaning. My preference is for J.I. Packer's six distinctives of evangelicalism, which are endorsed by John Stott and Alister McGrath, all three of whom are prominent evangelical Anglicans.
1. The supreme authority of Scripture for knowledge of God and as guide to Christian living.
2. The majesty of Jesus Christ as incarnate God and Lord, and the saviour of sinful humanity.
3. The lordship of the Holy Spirit.
4. The need for personal conversion.
5. The priority of evangelism for both individual Christians and for the Church as a whole.
6. The importance of Christian community for spiritual nourishment, fellowship and growth.
For an exposition of these points, see Alister E. McGrath, Evangelicalism and the Future of Christianity, Inter-Varsity Press, 1995, ch. 2, "Evangelical Distinctives").
