James Buckley is the author of this famous article, 'Rumination on Modern Theology'. The four theological sources in Christianity have been used by the author in a effective manner to convey his message, regarding the concept of modern theology. Furthermore, the author also addresses the challenges and needs that were addressed in Magna Carta by Ken Surin's. Apart from adressing these challenges and needs, the author also presents us with some new challenges and needs that should be addressed, as well (Buckley, 2010, p. 21).
