Translations and commentaries
His translation of the Satires of Horace made him known as a scholar, but his liberalism led to his suspension. He then went to London, where he became known to Baron Petre, who enabled him to proceed with a new translation of the Bible for English Roman Catholics, which he carried on as far as the Book of Second Chronicles and the Prayer of Manasseh which was published in 2 volumes (1792–1797). A translation of Psalms was published in 1807.
This was followed by Critical Remarks on the Hebrew Scriptures (1800), in which he largely anticipated the German school of Higher Criticism. The result of this publication was Geddes's suspension from all ecclesiastical functions. Arguing for the mythic character of the Pentateuch, he cast doubt not on those books' veracity but their historicity, seeing in the Fall for example "the mythic account of the painful condition of human life," rather than a historical chronicle.
He died without recanting, but received absolution at the hands of a French priest, though public mass for his soul was forbidden by the ecclesiastical powers.
He is buried next to the south-east corner of St. Mary's Church in Paddington, London.
