Following his ordination as a priest in 1959, he served in parishes in Whiteinch and Partick in Glasgow before spending more than two decades teaching at Blairs College, near Aberdeen, from 1964 to 1986.
He later served as parish priest in Blairs and Inverurie, and was appointed a Canon of St Mary’s Cathedral in Aberdeen in 1995. Following Archbishop Mario Conti’s move to Glasgow in 2002, he acted as diocesan administrator before being appointed bishop the following year.
An accomplished classical scholar fluent in French, Italian and Spanish, Bishop Moran co-founded Aberdeen’s French-speaking Catholic community.
Outside of his ministry, he was a keen pianist, built and sailed boats, and had a deep appreciation for Doric language and poetry.
During his time as bishop, he was closely involved with the Scottish Catholic International Aid Fund (Sciaf), ecumenical relations, and served as Bishop Promoter for the Apostleship of the Sea, the Church’s ministry to seafarers.
He is survived by his three sisters, including Columban Sister Elizabeth Moran, who also lived at Northcote Lodge Care Home.
The diocese said funeral arrangements would be announced in due course.
