That book which contains the prayers and ceremonies to be used by the minister in the administration of the sacraments and sacramentals, especially those included in the Gelasianum, Alcuin’s Appendix to the Gregorianum and the Ordines. The need for such a manual arose in the early Church; the first instance of such a collection is the Liber Ordinum, which dates from the latter half of the 7th century.

Rituals for the secular clergy date only from the 14th century, and these, in a large degree, were compilations of the individual priests: Official diocesan rituals appeared only at the end of the 15th century. They are called , , , , , . The publication of the first official Roman Ritual was ordered by Pope Paul V in the year 1614. This was revised by Pope Benedict XIV in 1742 and re-edited by Pope Leo XIII in 1884.
