 Owing to the enactment being delayed by the Suspensory Act 1914, seventeen parishes (including Sarn) were balloted by the Welsh Church Commissioners to ask whether they wanted to remain part of the Church of England or join the Church in Wales.This was because their parish boundaries crossed the border between England and Wales.Holy Trinity Church's parishioners voted 595–289 to remain part of the Church of England despite the church being located within Wales.
