"The economy of salvation” is an ancient phrase used by everyone from the Eastern Orthodox theologians of old to pioneer Pentecostal preacher Phoebe Palmer to thinkers across the Christian spectrum today. Technically, it refers to divine stewardship, God’s “household management” (oikonomia), but also to elements of trade: God’s gift, our response.
In our time not “the economy of salvation” but “the economy and salvation” is the hotter topic. Economists and prophets alike debate the place of riches and poverty, social engineering and radical choice, free markets and unfree markets in relation to religion.
Sometimes “the economy of salvation” is heard in discussions of the marketing of religions in a world of choice.
