POPE #140
Pope John XVII
The 140th Pope of the Catholic Church
John XVII
Pope John XVII had one of the shortest pontificates of the Middle Ages, reigning for less than five months. Although little documentation survives from his time as pope, his election came during an important transition after the death of the great scholar-pope Sylvester II and the political upheaval following the death of Emperor Otto III.
Unlike many earlier popes of the tenth century, John XVII’s pontificate was relatively peaceful. No major political crises, antipopes, or violent revolts are associated with his brief reign. Instead, he quietly maintained the ordinary life of the Church until his death later that same year.
“Watch ye, stand fast in the faith, do manfully, and be strengthened.”
