Chubb made his first appearance as an author in the Arian controversy. A dispute having arisen about William Whiston's argument in favour of the supremacy of the one God and Father, he wrote an essay, "The Supremacy of the Father Asserted", which Whiston pronounced worthy of publication, and it was printed in 1715. Another of his published tracts, "The Previous Question with Regard to Religion", went through four editions, three in 1725. His tracts were collected in a quarto volume in 1730 and attracted wide notice. (A second, two-volume edition in 1754 included 35 tracts.) Chubb was encouraged to write further tracts. A disciple of Samuel Clarke, he gradually moved from Arianism into a modified Deism.
