The Catholic Church, also known as the Roman Catholic Church, is the world's largest Christian church, with more than one billion members. Led by the Pope, it defines its mission as spreading the Gospel of Jesus Christ, administering the sacraments and exercising charity.

The Catholic Church is among the oldest institutions in the world and has played a prominent role in the history of Western civilisation. It teaches that it is the one true Church founded by Jesus Christ, that its bishops are the successors of Christ's apostles and that the Pope is the sole successor to Saint Peter.

Catholic doctrine maintains that the Church is infallible when it dogmatically teaches a doctrine of faith or morals. Catholic worship is centred on the Eucharist in which the Church teaches that bread and wine become the body and blood of Christ.

The Church holds the Blessed Virgin Mary in special regard. Catholic beliefs concerning Mary include her Immaculate Conception without original sin, her Motherhood of God and her bodily Assumption into Heaven at the end of her earthly life.

Stephen John Fry (born 24 August 1957) is an English actor, screenwriter, author, playwright, journalist, poet, comedian, television presenter, film director, and a director of Norwich City Football Club.

After a troubled childhood and adolescence, during which he was expelled from a number of schools and eventually spent three months in prison for credit card fraud, he was able to secure a place at Queens' College, Cambridge, where he studied English Literature.

He first came to public attention in the 1981 Cambridge Footlights Revue presentation "The Cellar Tapes", which also included Hugh Laurie, Emma Thompson and Tony Slattery. With Hugh Laurie, as the comedy double act Fry and Laurie, he co-wrote and co-starred in A Bit of Fry & Laurie, and took the role of Jeeves (with Laurie playing Wooster) in Jeeves and Wooster.

As an actor, Fry played the lead in the film Wilde, was Melchett in the BBC television series Blackadder, starred as the title character Peter Kingdom in the ITV series Kingdom, has a recurring guest role as Dr. Gordon Wyatt on the Fox crime series Bones and appeared as rogue TV host Gordon Deitrich in the dystopian thriller V For Vendetta. He has also written and presented several documentary series including the 2008 television series Stephen Fry in America, which saw him travelling across all 50 US states. Since 2003 he has been the host of the quiz show QI.

Christopher Eric Hitchens (13 April 1949 – 15 December 2011) was an English American author and journalist whose career spanned more than four decades. Hitchens, often referred to colloquially as "Hitch", was a columnist and literary critic for New Statesman, The Atlantic, The Nation, The Daily Mirror, The Times Literary Supplement and Vanity Fair. He was an author of twelve books and five collections of essays. As a staple of talk shows and lecture circuits, he was a prominent public intellectual, and his confrontational style of debate made him both a lauded and controversial figure.

Hitchens was known for his admiration of George Orwell, Thomas Paine and Thomas Jefferson, as well as for his excoriating critiques of various public figures including Mother Teresa, Bill Clinton, Henry Kissinger and Diana, Princess of Wales. Although he supported the Falklands War, his key split from the established political left began in 1989 after what he called the "tepid reaction" of the Western left to the Rushdie Affair. The September 11 attacks strengthened his internationalist embrace of an interventionist foreign policy, and his vociferous criticism of what he called "fascism with an Islamic face." His numerous editorials in support of the Iraq War caused some to label him a neoconservative, although Hitchens insisted he was not "a conservative of any kind", and his friend Ian McEwan describes him as representing the anti-totalitarian left.

Peter John Kreeft (born 1937) is a professor of philosophy at Boston College and The King's College. He is the author of numerous books as well as a popular writer of Christian philosophy, theology and apologetics. He also formulated, together with Ronald K. Tacelli, SJ, "Twenty Arguments for the Existence of God".

Kreeft took his A.B. at Calvin College (1959), and an M.A. at Fordham University (1961). In the same university he completed his doctoral studies in 1965. He briefly did post graduate studies at Yale University.

Kreeft has received several honors for achievements in philosophical reasoning. They include the following: Woodrow Wilson, Yale-Sterling Fellowship, Newman Alumni Scholarship, Danforth Asian Religions Fellowship, and Weathersfield Homeland Foundation Fellowship.

He joined the Philosophy faculty of the Department of Philosophy of Boston College in 1965. His intellectual reputation stems from his strengths in debating and summarizing the philosophical arguments of the major Western philosophers. He has debated several academics in issues related to God's existence. Shortly after he began teaching at Boston College he was challenged to a debate on the existence of God between himself and Paul Breines, an atheist history professor, which was attended by a majority of undergraduate students. Kreeft later used many of the arguments in this debate to create the Handbook of Christian Apologetics with then undergraduate student Ronald K. Tacelli, S.J..
