Came across this pithy quote regarding Christian doctrine…
Tradition without history has homogenized all the stages of development into one statically defined truth; history without tradition has produced a historicism that relativizes the development of Christian doctrine in such a way as to make the distinction between authentic growth and cancerous aberration seem completely arbitrary. (Pelikan, Byzantine Theology-Historical Trends and Doctrinal Themes, New York, 1979, 2nd ed., p. 224)
