For this sixth Sunday of Easter, I would like to continue with the first letter of St. Peter, which is our second reading for this weekend. Peter says, “Always be ready to give an explanation to anyone who asks you for a reason for your hope.” In many ways, this is the master text for theologians and apologists up and down the centuries to the present day. Something that is distinctive to biblical Christianity is that, from the beginning, it has been very interested in doctrine and expressing doctrine clearly and articulately.
