in church-history, a religious order of Christians, reformed from the Bernardins by pope Celestine V. Their rules are divided into three parts; the first, of the provincial chapters, and the elections of superiors; the second contains the regular obervances; and the third, the visitation and correction of the monks.

The Celestins rise two hours after midnight to say matins: they eat no flesh at any time, except when they are sick: they fast every Wednesday and Friday to the feast of the exaltation of the holy cross; and from that feast to Easter, every day.
