In Christian monasticism (especially Catholic, Orthodox, Anglican and Methodist), an oblate is a person who is specifically dedicated to God or to God's service.
Oblates are individuals, either laypersons or clergy, normally living in general society, who, while not professed monks or nuns, have individually affiliated themselves with a monastic community of their choice. They make a formal, private promise (annually renewable or for life, depending on the monastery with which they are affiliated) to follow the Rule of the Order in their private life as closely as their individual circumstances and prior commitments permit. Such oblates do not constitute a separate religious order as such, but are considered an extended part of the monastic community, and as such, Benedictine oblates also often have the letters OblSB or ObSB after their names on documents. They are comparable to the tertiaries associated with the various Orders of friars.
The term "oblate" is also used in the official name of some religious institutes as an indication of their sense of dedication.
The word oblate (from the Latin oblatus - someone who has been offered) has had various particular uses at different periods in the history of the Christian church.
The children vowed and given by their parents to the monastic life, in houses under the Rule of St. Benedict, were commonly known by this term during the century and a half after its writing, when the custom was in vogue, and the councils of the Church treated them as monks. This practice continued until the Tenth Council of Toledo in 656 forbade their acceptance before the age of ten and granted them free permission to leave the monastery, if they wished, when they reached the age of puberty. The term puer oblatus (used after that Council) labels an oblate who had not yet reached puberty and thus had a future opportunity to leave the monastery, though puer oblatus can also refer to someone entering an abbey. At a later date the term "oblate" designated such lay men or women as were pensioned off by royal and other patrons upon monasteries or benefices, where they lived as in an almshouse or homes.
