Bethani is a Welsh-speaking church. Since Reverend W. Nantlais Williams, who came under the influence of the Holy Spirit in November 1904, was minister, evangelical truths have provided the foundations for its existence, with Christ at its centre. This is reflected in the ministry today.
Two services are held every Sunday, at 10:15am and 5:30pm (2:30pm during the winter) and there is a prayer meeting and Bible class on 10am on Tuesdays.
