Pragmatism in the Church

I am not as moved now as I used to be by the tyranny of the urgent and by the need to respond to every trendy view that blows across the cultural sea in America. Well past midlife, I have a deep confidence that the best way to be lastingly relevant is to stand on rock-solid, durable old truths, rather than jumping from one pragmatic bandwagon to another. - John Piper (26/04/1998)

It's alarming that the church today sometime undiscerningly jump onto so-called "christian" movements just because the majority is raving about it and because statistics show it raking in the numbers.

Since when has the numbers game been in play in the case of religion? Is not quality more important than quantity?
