After graduating from Heythrop, he went to doctoral studies in Rome at the
Pontifical Gregorian University. In 1963, he graduated from Rome and returned to Heythrop to teach
Fundamental theology. He would teach at the college on other subjects such as
scripture,
patristics,
ecclesiology and
pastoral theology, until his retirement in 1999. Murray could understand Latin, Greek, Hebrew and Aramaic, more than a couple of European languages, but he specialised in Syriac. He wrote two books that utilised his knowledge of theology and numerous languages:
Symbols of Church and Kingdom. A Study in Early Syriac Tradition (Cambridge, 1975) and
The Cosmic Covenant (London, 1992). ==Bibliography==
