After training for the ministry at the Presbyterian College in Carmarthen and afterwards at Highbury College, London, he spent about eighteen months in Cincinnati, Ohio, where he was ordained to the Christian ministry.

He returned to Wales and in 1850 he was inducted minister at Bwlchnewydd and Gibeon in Carmarthenshire, before succeeding his father as the principal of Bala Independent College in 1855.

His name is closely linked with the attempt to establish a Welsh settlement in Patagonia, Argentina, in the 1860s where Welsh would be the language of religion, government, trade, and education.

The 150th anniversary (28 July 1865) of this Welsh-Argentine settlement in Rawson, Chubut Argentina was celebrated in 2015.
