Intercession of the Saints is an ancient doctrine of the Orthodox Church. It teaches that the saints in heaven pray for the children of God on earth.
As Christians, we pray to the saints, asking for their prayers, that they may intercede on our behalf, for “The effective, fervent prayer of a righteous man avails much” (James 5:16, NKJV). Just as we ask our friends on earth to pray for us, so do we ask our holy friends in heaven!
