"May the intercession of blessed Sabbas the Abbot commend us unto Thee, we beseech Thee, O Lord: so that what we cannot acquire by any merits of ours, we may obtain by his patronage. Through our Lord." - Roman Catholic Daily Missal, 1962
“St. Sabbas was a hermit, born at Mutalaska near Caesarea in Cappadocia, 439; died in his laura 5 December, 532. He entered a Basilian monastery aat the age of eight, came to Jerusalem in 456, lived five years in a cavern as a disciple of St. Euthymius, and, after spending some time in various monasteries, founded (483) the Laura Mar Sabe (restored in 1840) in the gorges of the Cedron, southeast of Jerusalem. Because some of his monks opposed his rule and demanded a priest as their abbot, Patriarch Salustius of Jerusalem ordained him in 491 and appointed archimandrite of all the monasteries in Palestine in 494. The opposition continued and he withdrew to the new laura which he had built near Thekoa. A strenuous opponent of the Monophysites and the Origenists he tried to influence the emperors against them by calling personally on Emperor Anastasius at Constantinople in 511 and on Justinian in 531. His authorship of “Typicon S. Sabæ” (Venice, 1545), a regulation for Divine worship throughout the year as well as his authorship of a monastic rule bearing the same title (Kurtz in “Byzant, Zeitschrift”, III, Leipzig, 1894, 167-70), is doubtful. After him was named the Basilica of St. Sabbas with its former monastery on the Aventine at Rome. His feast is on 5 December.” 1914 Catholic Encyclopedia
