This summer marks the 50th anniversary of Humanae Vitae, one of the most famous and perspicacious writings from the Catholic Church in the 20th Century. The encyclical reaffirmed the ancient teaching of the church that love, sex, marriage, and family formation were, by nature, inextricably bound together, and that artificial contraception and abortion were destructive of these gifts.

So by the rules of the game today, could I, as commentary editor, find a freelance writer who advertises his wares online and force him to write me an op-ed celebrating Humanae Vitae, and condemning the contraceptive culture we live in? Could my friends at First Things magazine do the same? If a writer refused this First Things commission on the grounds that he disagreed this Catholic teaching, would he be guilty of anti-Catholic discrimination?
