John IX bar Shushan was the Syriac Orthodox Patriarch of Antioch (1063—1073)
The Patriarchs of Antioch and the Pope of Alexandria had for many years kept in close touch with one another. More than once their relations were strained, as happened particularly in the time of Patriarchs John IX bar Shushan, and Christodulus, when they fell out over the proper presentation of the Eucharistic oblations, in which the Lyrian Jacobites were in the habit of mingling a little oil and salt (Neale, Patriarchate of Alexandria, II, 214). Christodulus insultingly rejected the practice, and John of Antioch wrote in its defence. In 1169 a new controversy, about the use of auricular confession severed the once friendly relations between the two communions.
