with regular services in Gaelic are St Columba's Church, Glasgow and Greyfriars Tolbooth & Highland Kirk, Edinburgh. —a shorter Gaelic version of the English-language Book of Common Order—was published in 1996 by the Church of Scotland. The widespread use of English in worship has often been suggested as one of the historic reasons for the decline of Gaelic. The Church of Scotland is supportive today, but has a shortage of Gaelic-speaking ministers.
