(Saint) Pope (April 12) (4th century) A Roman, who succeeded Saint Mark (A.D. 337), and on an appeal from the East justified Saint Athanasius against his Arian accusers. He celebrated a Council in Rome (A.D. 341) and the more important one at Sardica (Sofia), regarded as an Appendix to that of Nicaea. Throughout his Pontificate, Saint Julius upheld the Orthodox doctrine concerning the Most Holy Trinity, and asserted with vigour the supreme authority of the See of Rome, as well in the East as in the West. He died A.D. 352.
