“the Reformed Christian has never believed that America is a Christian nation and that, accordingly, our social institutions and formations, though blemished here and there, are fundamentally in accord with God's will. But neither has she agreed with those Christians who hold that our social institutions and formations are fundamentally corrupt and that the duty of the Christian is to withdraw. Normative discrimination is what she has always regarded as the appropriate stance, coupled with the attempt, once the discrimination has been made, to change what is wrong when that proves possible, to keep discontent alive when change proves not possible, and always to be grateful for what is good. In short, to act redemptively. While praying the prayer, "Thy kingdom come," to join God's cause of struggling against all that resists and falls short of God's will and longing for creation, thus to acknowledge the rightful, and ultimately effective, rule of Jesus Christ over every square inch of creation.”
