It is well, as St. Paul said, for every man to be fully assured in his own mind.[399] A doubting conscience enfeebles a man’s spiritual vigour for work. The Essenes found a remedy for morbidness in strictness as to meats and minute directions for the employment of time. St. Paul taught that an unhealthy casuistry would be best counteracted by doing all things unto the Lord. “He that eateth eateth unto the Lord, for he giveth God thanks; and he that eateth not, unto the Lord he eateth not, and giveth God thanks. For none of us liveth to himself, and none dieth to himself. For whether we live, we live unto the Lord; or whether we die, we die unto the Lord.”[400] The author of the Epistle to the Hebrews considers that it betokens a littleness of soul to strengthen conscience by regulations as to various kinds of food. The noble thing[401] is that the heart—that is, the conscience—be stablished by thankfulness,[402] which will produce a strong, placid, courageous, and healthy moral perception. The moral code of the New Testament is direct and simple. It is entirely free from all casuistical crotchets and distinctions without a difference. Those who busy themselves[403] about such matters have never gained anything by it. Do the Essenes repudiate the altar the sacrifice of which may not be eaten? Do they teach that the only sacrifice for sin is the daily meal? This is a fatal error. “We _have_” says the Apostle, “an altar of which the worshippers are not permitted to eat.”[404] All these expressions are metaphorical. By the altar we must understand the atoning sacrifice of Christ; by “those who serve the tabernacle” are meant believers in that sacrifice, prefigured, however, by the priests and worshippers under the old covenant; and by “eating of the altar” is meant participation in the sacredness that pertains to the death and atonement of Christ. The purpose of the writer is to teach the entire separateness of Christ’s atonement. It is true that Christians eat the body and drink the blood of Christ.[405] But the words of our Lord and of St. Paul[406] refer to the passover, whereas our author speaks of the sin-offering. In the former the lamb was eaten;[407] in the latter the carcases of the beasts whose blood was brought by the worshipper through his representative,[408] the high-priest, into the holiest place on the day of atonement, were carried forth without the camp and burned in the fire.[409] Both sacrifices, the passover and the sin-offering, were typical. The former typified our participation in Christ’s death, the latter the separateness of Christ’s death. Many expositors see a reference in the Apostle’s words to the Lord’s Table, and some of them infer from the word “altar” that the Eucharist is a continual offering of a propitiatory sacrifice to God. It is not too much to say that this latter doctrine is the precise error which the Apostle is here combating.
