The unauthorised publication of a correspondence which had passed between him and John Jackson on the Arian tendency of Samuel Clarke's "Scripture Doctrine of the Trinity" drew from Waterland "A Vindication of Christ's Divinity", Cambridge, 1719, in which he attacked not only Clarke, but Daniel Whitby. Whitby replied, and Waterland published an "Answer" to his reply, Cambridge, 1720. The "Eight Sermons in Defence of the Divinity of our Lord Jesus Christ", his Moyer Lectures in St Paul's Cathedral, published at Cambridge in 1720, were reprinted at Oxford in 1815.
