This quote is scary because it sounds like it was written about today's society. If Luther saw this occurring in age, just imagine how appalled he'd be today.
"Most married people do not desire children; in fact, they dislike them and hold that it is better to live without them because they are poor and do not have the wherewithal to support a family. This is true particularly of those who are given to idleness and laziness and flee from the sweat and labor of married life. But the purpose of marriage is not pleasure and ease but the procreation and education of children and the support of a family. This is truly an immense burden, full of great cares and labors. But that is why God created you: to be a husband or a wife and to learn to bear these molestations. People who do not like children are swine, dunces, and blockheads, not worthy to be called men and women, because they despise the blessing of God, the Creator and Author of marriage."
Martin Luther, as quoted in What Luther Says: A Practical In-Home Anthology for the Active Christian
