In these uncongenial days in which we find ourselves, "religion" is routinely tarred and feathered and set on fire. I understand why, at least in some instances. Nevertheless, I don't think it need be. It is still useful to be able to speak of religion rightly construed. Especially if religion is defined, as it has been in the past, in a fine way.
Louis Berkhof does well in his
Introductory Volume to Systematic Theology (pushlished as
Systematic Theology:
New Combined Edition, Kindle, Location 2197). The following definition of "religion" is taken from the chapter titled "Religion," which chapter comes within a larger section called "Principia of Dogmatics":
Religion consists in a real, living and conscious relationship between a man and his God, determined by the self-revelation of God, and expressing itself in a life of worship, fellowship, and service.
As I said, Berkhof does well. If we mean this when we speak of "religion," we shall also do well. And there shall be no need of lambasting religion rightly construed.
