It was Forms of Prayer and Administration of the Sacraments and Catechism of the Christian Faith, translated from English by Bishop John Carsewell of the Isles.
The Book of Common Order, originally titled The Forme of Prayers, is a liturgical book by John Knox written for use in the Reformed denomination. The text was composed in Geneva in 1556 and was adopted by the Church of Scotland in 1562. In 1567, Séon Carsuel (John Carswell) translated the book into Scottish Gaelic under the title Foirm na n-Urrnuidheadh. His translation became the first Gaelic text to be printed in Scotland. In 1996 the Church of Scotland produced “Leabhar Sheirbheisean”, a Gaelic supplement to the Book of Common Order.
