The fullest reference book available on the subject of Christianity, it's history and antecedents, and all it's forms.
From Greek Orthodox to evangelical and ancient philosophers to those of the last century, this one book includes entries on all the people and events down the ages that have made Christianity all it is today.
Saints and theologians, clergy and laity, thinkers and doers all have their place here; as do the many and various doctrines of the different elements of the church, and the often tragic events that have sprung out of those differences.
