The Lord's Supper stands, however, in the same relation, analogically, to Christ's sacrifice, as the Jews' sacrificial feasts did to their sacrifices (compare Mal 1:7, "altar ... table of the Lord"), and the heathen idol feasts to their idolatrous sacrifices (Is 65:11). The heathen sacrifices were offered to idol nonentities, behind which Satan lurked. The Jews' sacrifice was but a shadow of the substance which was to come. Our one sacrifice of Christ is the only substantial reality; therefore, while the partaker of the Jew's sacrificial feast partook rather "of the altar" (1Co 10:18) than of God manifested fully, and the heathen idol-feaster had fellowship really with demons, the communicant in the Lord's Supper has in it a real communion of, or fellowship in, the body of Christ once sacrificed, and now exalted as the Head of redeemed humanity.
