Pope Saint Hyginus was pope from about 138 to about 140. He was born in Athens, Greece at an unknown date. During his papacy, he determined the different prerogatives of the clergy, and defined the grades of the ecclesiastical hierarchy. Hyginus instituted godparents at baptism to assist the newly born during their Christian life. He also decreed that all churches be consecrated. He is said to have died a martyr under the persecution of Roman Emperor Marcus Aurelius, though no records verify this. The chronology of these bishops of Rome cannot be determined with any degree of exactitude by the help of the authorities at our disposal today.1
