Mar Joseph II Sliba Marouf (or Youssef II Sliba Bet Macruf) was the second incumbent of the Josephite line of Church of the East, a little patriarchate in full communion with the pope active in the areas of Amid and Mardin in the 17th–19th century.
Sliba Marouf was born in 1667[1] in Tel Keppe, Ottoman Empire, received first orders at fourteen,[2] and was consecrated bishop, without the previous consent of Rome, at the age of 24 in 1691 by Joseph I.
[3]: 209 He was chosen by Joseph I as his successor in 1694, but this appointment became effective only when Rome accepted his predecessor's resignation in 1696.
Thus Sliba Marouf was confirmed patriarch by Holy See on June 18, 1696,[3]: 209 with the name of Joseph II.
Early in 1713 he chose a successor Timothy Maroge and died of plague a few months later in 1713[3]: 209 [4]: 52 (or according to other sources in 1712) at the age of 46.
