Bangalore. Thus he became a professor in Sacred Scripture at St. Peter's Pontifical Institute. After a short period of probation, he was sent to Rome for his higher studies from 1980 to 1984, from where he received his licentiate in sacred scripture (LSS) from the Biblical Institute, Rome, run by the Jesuits. Then he came back to the seminary and taught sacred scripture for the seminarians. Again, from 1991 to 1994, he went to Paris, France, for his doctoral studies in the Catholic University, Paris (STD); he graduated "Summa Cum Laude". He had also received earlier a diploma in Biblical studies at the Hebrew University, Jerusalem.
