Though the World Council of Churches' consensus document Baptism, Eucharist, and Ministry is a work of enormous significance, it may strike one as bland. Gordon Lathrop, a Lutheran theologian, presents much the same material in two books (the first published in 1993) that are lively, provocative and challenging.
There is a good chance that you are a cyborg. A cyborg is a cybernated organism—which is anyone whose normal biological systems are enhanced or extended by technological mechanisms, especially electronic and communication devices. The word "cybernetics" comes from the Greek word for "steersman" (kubernetes) and describes one who is in control, who is both flexible and agile in response to a given environment and who can tame it to certain ends. To the extent that we exercise such control through technological devices, our lives have become cybernated. If you have a hearing aid, a pacemaker or an artificial limb, if you use a computer or telephone or drive a car, you are a cyborg.
