The cosmic story presented by modern science reveals an evolutionary nature of the universe and origin of life forms including humans. The Catholic Church has repeatedly expressed that theory of evolution is not incompatible with faith, but how to respond to the challenges posed by such an acceptance has not been clearly stated. So the pastors and faithful tend to either completely ignore evolution while explaining their faith or provide an ambiguous answer. The author endorses that one can be a believer and accept evolution and attempts to answer the questions that arise in the minds of the faithful regarding the impact of evolution on Catholic faith. This book, drawing inspiration from the Catholic theological tradition and modern Christian theologians, explains the divine action in creation, the meaning of original sin and incarnation and the belief in resurrection of body in a way that is congruent with established scientific thought. This book is a good resource for pastors, lay leaders and faithful who are interested to live and explain their faith in this age of science.
