Catholicism is a broad term for the body of the Catholic faith, its theologies and doctrines, its liturgical, ethical, spiritual, and behavioral characteristics, as well as a religious people as a whole.

For many the term usually refers to Christians and churches, western and eastern, in full communion with the Holy See, known alternatively as the Catholic Church or as the Roman Catholic Church. However, many others use the term to refer to other churches with historical continuity from the first millennium.

In the sense of indicating historical continuity of faith and practice, the term "catholicism" is at times employed to mark a contrast to Protestantism, which tends to look solely to the Bible as interpreted on the principles of the 16th-century Protestant Reformation as its ultimate standard. It was thus used by the Oxford Movement.

According to Richard McBrien, Catholicism is distinguished from other forms of Christianity in its particular understanding and commitment to tradition, the sacraments, the mediation between God, communion, and the See of Rome. According to Orthodox leaders like Bishop Kallistos Ware, the Orthodox Church has these things as well, though the primacy of the See of Rome is only honorific, showing non-jurisdictional respect for the Bishop of Rome as the "first among equals" and "Patriarch of the West". Catholicism, according to McBrien's paradigm, includes a monastic life, religious institutes, a religious appreciation of the arts, a communal understanding of sin and redemption, and missionary activity.

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..

Michael Coren (born January 15, 1959) is an English-Canadian columnist, author, public speaker, radio host and television talk show host. He hosted the television talk show The Michael Coren Show on the Crossroads Television System from 1999 to 2011 when he moved to the Sun News Network to host an evening talk show, The Arena with Michael Coren. He has also been a long-time radio personality, particularly on CFRB radio.

He has written more than ten books, including biographies of G.K. Chesterton, H. G. Wells, Arthur Conan Doyle, and C. S. Lewis. His latest book, Why Catholics are Right, was published in 2011.

Coren was born in Essex, England. After obtaining a degree in politics from Nottingham University, he moved from the UK to Canada in 1987. For several years, he was a columnist for Frank and then The Globe and Mail, before he began syndicated columns for the Financial Post and Sun Media in 1995. Following his departure from Frank, he became a favourite target of that publication, culminating in a spoof ad contest to "deflower" Michael Coren (a nod to Frank's notorious "Deflower Caroline Mulroney" contest, and a satirical jab at Coren's conservative leanings.) Coren had also been a favorite target of Frank back in the days before he began writing for them. Coren took exception to being labelled a "literary prostitute" during a 1994 interview.

Kenneth Copeland (born December 6, 1936 in Lubbock, Texas) is an American author, public speaker, and televangelist. He is the founder of Kenneth Copeland Ministries, and known for teaching “prosperity message ” which says that believers can become wealthy through tithing, giving offerings and using faith, as well as sound financial practices.

Prior to his conversion to Christianity in November 1962, Copeland was a recording artist on the Imperial Records label, having one Billboard Top 40 hit ("Pledge of Love", which charted in the Top 40 on April 20, 1957, stayed on the charts for eight weeks, and peaked at #12).

Following his religious conversion, Copeland turned the rest of his life over to the gospel and ministry work. In the 1960s, he was a pilot and chauffeur for Oral Roberts. In the fall of 1967, he enrolled in Oral Roberts University in Tulsa, Oklahoma.

Kenneth is married to Gloria Copeland. His children are John Copeland, Kellie Copeland and Terri Pearsons.
