No sacrifice would be acceptable to God which was not salted or seasoned with divine fire, which represented the communication between God and man that was opened through Jesus Christ alone. The holy fire which was to be put upon the censer was kept burning perpetually. And while the people of God were without, earnestly praying, the incense kindled by the holy fire was to arise before God mingled with their prayers. This incense was an emblem of the mediation of Christ. (Con 80.2) MC VC
