The responsibility of the church in the new age is the same as its responsibility in every age. It is to testify that this world is lost in sin; that the span of human life--no, all the length of human history--is an infinitesimal island in the awful depths of eternity; that there is a mysterious, holy, living God, Creator of all, Upholder of all, infinitely beyond all; that he has revealed himself to us in his Word and offered us communion with himself through Jesus Christ the Lord; that there is no other salvation, for individuals or for nations, save this, but that this salvation is full and free, and that whoever possesses it has for himself and for all others to whom he may be the instrument of bringing it a treasure compared with which all the kingdoms of the earth--no, all the wonders of the starry heavens--area as the dust of the street.
"An unpopular message it is--an impractical message, we are told. But it is the message of the Christian church. Neglect it, and you will have destruction; heed it, and you will have life." (From Selected Shorter Writings, edited by D.G. Hart, 376)
Reminds me of several things. First, that the purpose of the church is not to save children from AIDS or to end all poverty, or any other earth-oriented cause, however noble. It will do those things, but as a reflection of its real purpose, not as its actual purpose. That's where the social gospel goes wrong: it sees the church's task as the accomplishment of all good ends here and now. In reality, the church's goal must always be to make Christ known and to show how very deep our need for Him is. All those other things will come as part of that, but they are not it, and can never replace it. When they do, the church falters.
I'm also reminded of just how much I want to read some of J. Gresham Machen's writing; every time I run into it, I appreciate the things he has to say. Add one more to the already very long reading list. It keeps growing...
