INTERCESSION. Entreaty in favor of another person; hence mediation. In biblical language, "there is only one mediator between God and mankind, himself a man, Christ Jesus, who sacrificed himself as a ransom for them all" (I Timothy 2:5-6). The Blessed Virgin, Mediatrix of all graces, the angels, saints in heaven, souls in purgatory, and the faithful on earth intercede for mankind by their merits and prayers.
