The Church includes a number of monastic orders, i.e. monastery and nunnery institutions where keen believers take vows and live in fellowship and service to each other and the wider world, through prayer, scholarship and active charitable works or any combination of such devotions. One of the most major among these orders are the Benedictines (after St Benedict). How far back does the order's foundation date?
Almost 3/4 of the Christian era, to around 529 CE
To around the middle of the mediaeval period, roughly contemporary with Britain's Domesday Book &/or Magna Carta
To the counter-Reformation in the 16th Century
To the Age of Enlightenment (i.e. about 200-250 years)
