The referred topic has not been examined in educational, popular, or scientific literature yet. St Clement of Rome (who was most likely the third in line of succession to St Peter the Apostle) and themes related to him were also discussed in the official documents of the 19th-century Popes, namely in one brief (In Suprimo, 1839) of Pope Gregory XVI (1831 – 1846) and four encyclicals (Grande Munus, 1880; In Plurimus, 1888; Providentissimus Deus, 1893; Satis Cognitum, 1896) of Pope Leo XIII (1878 – 1903). The personality and work of the referred 1st century AD saint have usually been associated with Sts Constantine-Cyril and Methodius who transferred his relics to Rome in 867/868. However, the aforementioned papal documents bring other aspects of St Clement of Rome into the discussion too.
