Thomas Jones was born in 1756 at Aberwheeler in Denbighshire, but was educated at Caerwys and Holywell in Flintshire.
Jones worked with Charles to devise the "Rules and Design of the … Welsh Methodists" (1801) and both edited the Welsh-language periodical, Y Drysorfa' while the publication was still in its quarterly form.
Thomas Jones made significant contribution in content and style to Welsh theology.
He was a strong opponent of Arminianism, which was prominent among the Wesleyans, and translated The Christian in Complete Amor (1655–1662) by Williams Gurnal into Welsh under the title The Cristian in Full Armor (1796–1820).
Jones printed a substantial part of his work on a press which he set up at his home in Ruthin in 1804.
