recent sermon by Samuel Croxall arguing that to celebrate Charles I's martyrdom was inconsistent with celebrating William III's arrival. In 1734 came four tracts of his attacking the common theory of inspiration, arguing that the resurrection of Christ was no proof of his divine mission and criticising the story of Abraham's sacrifice of Isaac. The whole argument showed increasing scepticism, and the assertion about Abraham led to some controversy. He returned to the question in 1735, in some "Observations" on Thomas Rundle's nomination to the Diocese of Gloucester, Rundle having been accused of disbelieving the story. Three tracts were added that continued the former discussion. In 1738 Chubb published The True Gospel of Jesus Christ asserted, which provoked various attacks, including one from Ebenezer Hewlett. It was followed by The True Gospel of Jesus vindicated, and An Enquiry into the Ground and Foundation of Religion, wherein it is shown that Religion is founded on Nature. He persisted in stating that true Christianity consisted of a belief that morality alone could make men acceptable to God, that repentance for sin would secure God's mercy, and that there would be future retribution. His Enquiry into the Ground and Foundation of Religion (1740) includes a controversy with Henry Stebbing. Chubb argues against interpreting literally the command to give all to the poor, noting that Stebbing himself was a pluralist with two livings, a preachership and an archdeaconry, and due to be chancellor of the Diocese of Salisbury, so that he could hardly interpret the command literally to himself.

In 1743 his Enquiry concerning Redemption is a defence of himself against some sneers by William Warburton. "The Ground and Foundation of Morality considered" (1745) is an attack on Thomas Rutherforth's theory of self-love. The last work that Chubb published himself was Four Dissertations (1746), attacking some Old Testament passages with a freedom that gave wide offence. Views on prayer Joseph Waligore states in a 2012 article, "The Piety of the English Deists", that Chubb discussed prayer more than any other deist. Chubb's longest writing on the subject was a 30-page pamphlet, "An Enquiry Concerning Prayer", where he began by insisting that prayer was a duty God required for achieving a closer relationship with him. The purpose of prayer was to render someone "a suitable and proper
