People of substance may sin without being exposed for their stolen pleasure; but servants and the poorer sort of women have seldom an opportunity of concealing a big belly, or at least the consequences of it.
Christ didn't waste his time trying to change the social order. Christ spent all his time fighting sin. Therefore it behooves the witnesses of Christ to say that we do not have to abolish capitalism and establish socialism or communism, that sin can flourish under those systems as well. Christianity is not opposed to any social order, but to sin.
Sin has always been an ugly word, but it has been made so in a new sense over the last half-century. It has been made not only ugly but pass?. People are no longer sinful, they are only immature or underprivileged or frightened or, more particularly, sick.
