Fr. Brian Harrison, O.S.
The Rev. Brian W. Harrison, O.S., M.A., S.T.D., a priest of the Society of the Oblates of Wisdom, is an Associate Professor of Theology in the Pontifical Catholic University of Puerto Rico in Ponce, P.R.. He is also parochial vicar of the parish of Saint Joseph the Worker in the city of Ponce, and a 'Defender of the Bond' for the island's marriage tribunals.
He was born in Australia and, after being raised as a Presbyterian, converted to the Catholic faith in 1972. In 1979 he began studies for the priesthood in the major seminary of Sydney, and after completing his Licentiate in Theology at Rome's Angelicum university was ordained as a priest in Saint Peter's Basilica in 1985 by His Holiness Pope John Paul II. In 1997 he gained his doctorate in Systematic Theology, summa cum laude, from the Pontifical Athenæum of the Holy Cross in Rome.
Fr. Harrison, who has lived in Puerto Rico since 1989, is well-known as a speaker and writer. He is the author of two books and over 120 articles in Catholic magazines and journals in the U.S.A., Australia, Britain, France, Spain and Puerto Rico. His special interest in theological and liturgical matters, in keeping with the charism of the Oblates of Wisdom, is upholding a 'hermeneutic of continuity' between the teachings of Vatican Council II and the bimillennial heritage of Catholic Tradition.
