Peter John Kreeft (b. 1938/1939) is a professor of philosophy at Boston College and The King's College, and author of numerous books as well as a popular writer on Christian theology, and specifically Roman Catholic 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. He joined the Philosophy faculty of the Department of Philosophy of Boston College in 1965. In 1994 he was a signer of the document Evangelicals and Catholics Together.
Originally a Calvinist, Kreeft converted to the Catholic Church while in college. The "central and deciding" factor for his conversion was "the Church's claim to be the one Church historically founded by Christ."
