Grandson and namesake of a prominent citizen of Carmarthen who represented Carmarthen Boroughs in the 1614 Parliament, William Thomas rose to prominence in the Restoration Church largely through the patronage of the duke of York. During the Interregnum he had kept a school at Laugharne to support his growing family.
Thomas was passed over for promotion to the see of Bangor in 1665 by Sheldon, much to the disappointment of Clarendon who thought Thomas ‘a very worthy and good man’ whose elevation would have been ‘a very good compliment to the duke of York’.
During his parliamentary career Thomas attended six of nine possible sessions but of those only two (the brief sessions in spring 1679 and March 1681) for more than half of all sittings. When unable to attend the House in November 1678, he registered his proxy in favour of John Fell, of Oxford (vacated on 2 Dec.) and, in 1685, it was given by Sancroft, to William Lloyd, of Norwich (vacated at the end of the session). Thomas took his seat at a time of rising concerns about Catholicism that would soon be exploited by Titus Oates and his revelations of a popish plot. Given his own wholehearted protestantism and his dependence on the patronage of York, this presented him with a considerable political dilemma. In the summer of 1678 he organized the publication of his Apology. The ostensible focus of the work was to establish the error of nonconformist separation from the Church of England, and Thomas was anxious to make it clear that he had not altered the text from that which he had composed in the 1650s. Nevertheless, the timing of publication suggests another purpose and a close reading, suggested a clear anti-Catholic subtext. One of the reasons advanced for condemning nonconformist separation from the Church related to the encouragement it gave to Catholics who belonged to a church ‘disfigured by the scars and gashes of schism’. The whole tenor of the work was to reiterate orthodox Anglican political theology and to establish that the Anglican Church was the true church.
On 15 Nov. 1678, during the final session of the Cavalier Parliament, Thomas voted in favour of the Test. Allegations that the lawyer, Edward Whitaker, had attacked the entire episcopal bench as ‘papists’ prompted him to make an impassioned speech to the House on 14 Dec. 1678. Thomas defended the integrity of the bench against Whitaker’s ‘great service of the Church of Rome’, asserting the bishops’ commitment to protestantism and their willingness to die for their faith. He emphasized the seriousness of such aspersions, pointing out that in ancient Rome,
detraction was capital. Reputation is a civil life, which to all ingenuous spirits, to those of our function especially of our station in the Church is, at least ought to be more tender and precious than a natural. … We cannot possibly discover how far an infamy dispersed multiplies, how swiftly it flies, how indelibly it sticks. I say indelibly having frequently observed in the world that a multitude of men who have been prompt and keen to entertain the unjustest aspersion, have afterwards been regardless of the justest vindication.
The House, he continued, should make an example of the man not out of ‘any fierce vindictive design’ but ‘that others may be deterred from the like calumny’.
Thomas took his seat for the first Exclusion Parliament on 24 Mar. 1679 and was thereafter present for all but one of the remaining days in the session, 84 per cent of the whole. On 10 May 1679 he voted against the appointment of a joint committee of both Houses to consider a method of proceeding against the impeached lords. He arrived for the second Exclusion Parliament on 22 Oct. 1680 and was then present on all but four days until 20 Nov., opposing the exclusion bill on 15 November. He was then absent until 21 Mar. 1681, thereafter attending every day until the end of the session on 28 March.
In 1683 Thomas was translated to Worcester as its bishop, where he intended to use his power as visitor to the chapter to tackle irregularities in the cathedral liturgy. Whilst he feared such a step had the potential to upset the corporation, he insisted that he preferred to obey the instructions of his metropolitan than to court popularity in the city.
With the accession of James II to the throne, Thomas was forced to choose between his loyalty and his conscience. He was present on the first day of the new king’s Parliament on 19 May 1685 and attended intermittently until the adjournment on 2 July, approximately half the possible sitting days to that date. On 6 Nov., conscious that Parliament was about to reassemble, he wrote to Sancroft to excuse himself from attendance, his physician having ‘vehemently dissuaded’ him.
Thomas was already frail. When the Convention assembled on 22 Jan. 1689, he was too sick to attend. He remained in his diocese, absorbed with pastoral business. Two days before his death, he is said to have declared that ‘I think I could burn at a stake before I took this new oath’ to William and Mary.
William Thomas died on 25 June 1689. He requested a ‘frugal’ burial, the usual mourning expenses for rings and scarves being exchanged for clothing for the poor of Worcester. He left modest legacies to his family and believing it ‘a more prudential act’ to encourage industry and integrity than to relieve poverty, he left the residue of his estate towards apprenticeships for poor boys from Worcester and south Wales who could repeat the Anglican catechism. At his death an inventory at Hartlebury Castle valued his property at a little over £600.
