at least the early 1960s. He has been particularly critical of the doctrine of papal infallibility; the social teaching of the church regarding homosexuality, abortion, contraception, and the Eucharist; and of the church's reaction to the sex abuse scandal. In 1961, in a phone conversation with William F. Buckley Jr., Wills coined the famous macaronic phrase Mater si, magistra no (literally "mother yes, teacher no"). The phrase, which was a response to the papal encyclical Mater et magistra and a reference to the then-current anti-Castro slogan "Cuba sí, Castro no", signifies a devotion to the faith and tradition of the church, combined with a skeptical attitude towards ecclesiastical–church authority. Wills published a full-length analysis of the contemporary Catholic Church, Bare Ruined Choirs, in 1972 and a full-scale criticism of the historical and contemporary church, Papal Sin: Structures of Deceit, in 2000. He followed up the latter with a sequel, Why I Am a Catholic (2002), as well as with the books What Jesus Meant (2006), What Paul Meant (2006), and What the Gospels Meant (2008). Politics Wills began his career as an early protégé of William F. Buckley Jr. and was associated with conservatism. When he first became involved with National Review he did not know if he was a conservative, calling himself a distributist. Later on, he was self-admittedly conservative, being regarded for a time as the "token conservative" for the National Catholic Reporter. In the early 1980s, after having supported more liberal positions for 20 years, he wrote a book entitled Confessions of a Conservative, in which he described his break from William F. Buckley and the American conservative movement, while continuing to remain in some ways ethically and culturally conservative. However, during the 1960s and 1970s, driven by his coverage of both civil rights and the anti-Vietnam War movements, Wills became increasingly liberal. His biography of president Richard M. Nixon, Nixon Agonistes (1970) landed him on the master list of Nixon political opponents. He supported Barack Obama in the 2008 presidential election, but declared two years later that Obama's presidency had been a "terrible disappointment". In 1995, Wills wrote an article about the Second Amendment for The New York Review of Books. It was originally entitled "Why We Have No Right to Bear Arms", but that was not Wills' conclusion. He neither wrote the title nor approved it prior to the article's publication. Instead, Wills argued that
