Born into a poor mining family, Thomas started working as a coal miner at a very young age.
After being injured in a mine accident, he attended Richards Academy in Aberafon, where he started preaching. He went to Pontypool College in 1881, and from there won a scholarship of £30 to go to Bangor University.
After his first year at Bangor, he was awarded a bursary of £50 by Lord Penrhyn. He received his MA degree in Philosophy and Metaphysics at London University in honors.
He served as pastor at Saladine Nook, Huddersfield (1887–93); Myrtle Street Baptist Church, Liverpool (1893–1914); and Sutton (1915–20). In 1903–04 he traveled extensively in Europe and the Holy Land with his wife Deborah.
