A personal favourite of Queen Anne, Offspring Blackall is generally remembered for engaging in religious polemics with John Toland and Benjamin Hoadly†. Yet his career was also politically significant if only because his controversial elevation to the episcopate ignited a ministerial crisis. Once he became a bishop he found himself one of a Tory minority in an episcopate dominated by Whig bishops and was condemned as a Jacobite by Gilbert Burnet, bishop of Salisbury. Blackall had a puritan heritage through his maternal grandfather, Charles Offspring (Ofspring). His father, a propertied and armigerous City alderman, was originally from Oxfordshire but had settled in Dalston.
By 1693 Blackall had come to the attention of Henry Compton, bishop of London. At a time when churchmen were increasingly anxious about the effects of the Act of Toleration, a sermon by Blackall against religious sectarianism was particularly well received.
In 1707 Anne made a private promise of preferment to Blackall and William Dawes, the future bishop of Chester, another Tory cleric. When news leaked of her intentions, her ministers, desperate to shore up their parliamentary support by appeasing the Whig Junto, were appalled; the Junto Whigs were furious. John Somers, Baron Somers, demanded that Thomas Tenison, of Canterbury, block Blackall’s appointment. Tenison (despite boasting that he would speak ‘freely’ to the queen), prevaricated in the face of the queen’s obduracy.
The liberties of all Europe, the safety of your majesty’s person and of these kingdoms, the future preservation of the protestant religion, the strength of your government, and the glory of your reign, depend upon the success of next sessions of Parliament, & indeed upon every sessions of Parliament while this war lasts. … This being truly the case, what colour of reason can incline your majesty to discourage and dissatisfy those whose principles and interest lead them on with so much warmth and zeal to carry you through the difficulties of this war, and have already given you so many unquestionable proofs of their preferring your majesty’s interest and the support of your government, above all others? And what appearance will it have, what reflection will it not cause in the world, that all these weighty things together, cannot stand in the balance with this single point, whether Dr Blackall, at this time, be made a bishop or a dean or a prebend.

However, by October the opening of additional patronage opportunities for churchmen had calmed the situation. Edmund Gibson†, (later bishop of London) confided in William Wake, bishop of Lincoln and the future archbishop of Canterbury, that he believed it ‘agreed, on the Whig side, that Dr Blackhall’s going to Exeter shall break no squares.’
On 6 Jan. 1708 Anne made a formal announcement of Blackall’s nomination as bishop of Exeter.
Taking his seat four months after the start of the winter 1707 parliamentary session, Blackall attended for only ten days before the session closed on 1 Apr. 1708. There was no effort to enlist his support in the April 1708 Exeter by-election but the situation had changed by the time of the general election a month later. John Poulett, Earl Poulett, assuming that intervention by the bishop would swing the Exeter electorate, asked Harley to pressurize Blackall into supporting the Poulett candidate, Tory merchant Nicholas Wood‡. Wood was elected but Blackall’s role in the election is unclear. Blackall’s intervention was also sought by George Granville, later Baron Lansdown, who wanted the bishop’s assistance in electing Henry St John, the future Viscount Bolingbroke, for Lostwithiel against the interest of his local rival Charles Bodvile Robartes, 2nd earl of Radnor.
In May 1708 a printed list of party affiliation unsurprisingly marked Blackall as a Tory. He arrived ten days after the start of business for the November 1708 session and attended one quarter of the sittings. On 31 Jan. 1709 he preached a dour sermon before the House of Lords on the sins of the fathers being visited on their children.
The session ended on 21 Apr. 1709 and Blackall became immersed in a vicious dispute with Benjamin Hoadly†, the future bishop of Winchest, that sparked debate in Parliament about the concept of popular sovereignty and the constitutional role of the Lords. The altercation arose from Blackall’s sermon at St James on 8 Mar. 1709 (the anniversary of Anne’s accession) in which he took as his text the defining biblical sanction for absolute authority (Rom. 13:4).
Although listed as attending the Lords on 25 Jan. 1710 (his only attendance that session), it seems likely that, as Ralph Bridges later wrote he had been at Exeter all winter and had received private instructions from the queen to stay away from the House. Indeed, when the House divided on the question of guilt of Henry Sacheverell on 25 Mar., it was noted that Blackall was in the country.
On 5 Feb. 1711 he registered his dissent against the repeal of the General Naturalization Act. The following day, after the queen’s levée, Blackall and William Nicolson, bishop of Carlisle dined in Kensington where there was ‘Tory discourse’.
On 29 Nov. 1711 (in advance of the new session that opened on 7 Dec.) Blackall excused his inability to attend Parliament by reference to an outbreak of smallpox in the region and once more registered his proxy in favour of Dawes.
Blackall’s unswerving loyalty to the Oxford ministry was noted in spring 1713 in a party listing compiled by Jonathan Swift. His poor attendance, nevertheless, limited his usefulness to the ministry. On 14 Feb. he responded to a command to ‘hasten to London’ with an excuse about the delays caused by poor weather and an insistence that his inability to make anything other than short journeys would delay his arrival until the end of the month. His attendance record was so poor that he felt obliged to remind Oxford that he had indeed attended the previous session.
In May 1714 Daniel Finch, 2nd earl of Nottingham, forecast that Blackall would support the schism bill. On 11 June, in the division on extending the schism bill to Ireland, Blackall’s proxy was used by Dawes to carry the vote by 75 to 74. Four days later, in the main division on the bill, Blackall’s proxy was again used in support of the measure.
On 2 Sept. 1716, while on visitation in Cornwall, Blackall fell from his horse and suffered a serious injury. Gangrene set in and he died on 29 Nov. 1716.
