Christian philosophy may refer to any development in philosophy that is characterised by coming from a Christian tradition.

There is no record of any writing by Jesus, nor of any systematic philosophy or theology. Several accounts of his life and many of his teachings are recorded in the New Testament, and form the basis for some Christian philosophies, such as Jesusism.

Saul of Tarsus (later Paul the Apostle or St. Paul) was a Jew who persecuted the early Christian church and who helped to facilitate the martyrdom of Saint Stephen, a Greek-speaking Jewish Christian. Saul underwent a dramatic conversion, becoming a Christian leader who wrote a number of epistles, or letters, to early churches in which he taught doctrine and theology. In some ways he functioned in the manner of the popular marketplace philosophers of his day (Cynics, Skeptics, and some Stoics). A number of his speeches and debates with Greek philosophers are recorded in the Biblical Book of Acts, and his epistles became a significant source for later Christian philosophies.

Alister Edgar McGrath (born 23 January 1953) is an Irish Anglican priest, theologian, and Christian apologist, currently Professor of Theology, Ministry, and Education at Kings College London and Head of the Centre for Theology, Religion and Culture. He was previously Professor of Historical Theology at the University of Oxford, and was principal of Wycliffe Hall, Oxford until 2005.

McGrath is noted for his work in historical, systematic, and scientific theology, as well as his writings on apologetics and his opposition to antireligionism. He holds both a DPhil (in molecular biophysics) and an earned Doctor of Divinity degree from the University of Oxford.

McGrath was born in Belfast, Northern Ireland, and grew up in Downpatrick, County Down, where he attended Down High School. In September 1966 he became a pupil at the Methodist College Belfast, where his studies focused on mathematics, physics and chemistry. He went up to Wadham College, Oxford in 1971 and gained first class honours in chemistry in 1975. He began research in molecular biophysics in the Oxford University Department of Biochemistry under the supervision of Professor Sir George Radda, FRS and was elected to an E.P.A. Cephalosporin Research Studentship at Linacre College, Oxford, for the academic year 1975-6, and to a Domus Senior Scholarship at Merton College, Oxford, for the period 1976-8. During these three years, he carried out scientific research while studying for the Oxford University Final Honour School of Theology. He was awarded an Oxford D.Phil. for his research in molecular biophysics (December 1977), and gained first class honours in Theology in June 1978.
