That which brought him to prominence in Wales was his letter (under the pseudonym Brutus) in Seren Gomer, March 1824, attacking the Welsh language. Henceforth it was as ‘Brutus’ that he was known. Expelled by the Baptists, he became a member of the Independent church, Capel Newydd, and kept school at Llangian. He was allowed to preach amongst the Independents, but he did not become popular. Later, he moved to Tyddyn-sweep, Maenaddfwyn, near Llannerch-y-medd (Anglesey); but he was not very successful there either, and soon afterwards he moved to Bontnewydd, near Caernarvon, and kept a school there.
In 1828, after being appointed editor of Lleuad yr Oes, a journal published at Aberystwyth, he became a schoolmaster at Llanbadarn-fawr, but when the copyright of the magazine was bought in 1829 by Jeffrey Jones, the Llandovery printer, Brutus moved to Pentre-tŷ-gwyn. When Jeffrey Jones d. in 1830, Yr Efangylydd was launched, as successor to Lleuad yr Oes, by a committee of Independent ministers, with Brutus as editor, and Messrs. D. R. and W. Rees (qq.v.), Llandovery, as printers. Under the editorship of Brutus the new magazine became more political than had been intended, with a tendency towards political and ecclesiastical conservatism, and Brutus was threatened with expulsion from office. To resolve this conflict, Messrs. Rees launched a new journal, Yr Haul, with Brutus as editor, to serve the Established Church, and the Independents launched Y Diwygiwr, with D. Rees (1801-1869) (q.v.) as editor, in 1835. Brutus returned to the Anglican church, at Llywel, and moved to Pwllmadog, near Pentre-bach, between Llandovery and Trecastle. Later, he resided at Bronarthen, near Half-way. To the end of his life he continued to edit Yr Haul very ably, but he would occasionally attend Horeb, the Baptist chapel at Cwm-dŵr. It is remarkable that he never received holy orders in the Church. He d. 16 Jan. 1866, and was buried at Llywel, where there is a tablet to his memory.
He was a prolific writer, and published many religious and theological books, amongst them — Athrawiaeth Bedydd Babanod, 1828; Cwymp Babilon Fawr, 1829; Breinniau Babanod, 1830; Daearyddiaeth Ysgrythyrol, 1835; Allwedd y Cyssegr, 1835 (2nd ed. 1839); Christmasia, 1840 (2nd ed. 1861; 3rd. ed. 1887); Gweithrediadau yr Eglwys Sefydledig, 1841; Gwaedd Uwch Gwlad, 1843; Eliasia, 1844; Darganfyddiadau yn Ninefeh, 1852 (a translation of an English book by A. H. Layard); Brutusiana, 1855, a selection of his writings from Yr Haul, and Cofiant y Diweddar Barch. Thomas Williams, 1861. His importance lies in his work not as a scholar and theologian but rather as a satirist. The chief object of his satire was quackery, in particular the quackery of the worst Nonconformist preachers, the ‘Jacks,’ as they were called. It is these who are reviled in numerous articles, essays, and reviews; in the conversations of Bugeiliaid Epynt (Yr Haul, 1835-66) (Selections by T. Jones, 1950); and in Wil Brydydd y Coed (ibid., Sept. 1863-Dec. 1865), also published separately in 1876 and 1896.
