(Latin: intercedo, to interpose)
The going between two parties in order to plead before one on behalf of the other. In ecclesiastical usage the office of Mediator belongs primarily to Jesus Christ (Timothy 1; Hebrews 7). The Blessed Mother, Mediatrix of all Graces, the angels, the blessed in Heaven, the souls in Purgatory and the faithful on earth can intercede for us sinners by their prayers and merits.
