barn."--_Against Heresies_, b. iv. chap. viii. sects. 2, 3. The case of the priests on the Sabbath he thus presents:-- "And the priests in the temple profaned the Sabbath, and were blameless. Wherefore, then, were they blameless? Because when in the temple they were not engaged in secular affairs, but in the service of the Lord, fulfilling the law, but not going beyond it, as that man did, who of his own accord carried dry wood into the camp of God, and was justly stoned to death." Book iv. chap. viii. sect. 3. Of the necessity of keeping the ten commandments, he speaks thus:-- "Now, that the law did beforehand teach mankind the necessity of following Christ, he does himself make manifest, when he replied as follows to him who asked him what he should do that he might inherit eternal life: 'If thou wilt enter into life, keep the commandments.' But upon the other asking, 'which?' again the Lord replied: 'Do not commit adultery, do not kill, do not steal, do not bear false witness, honor father and mother, and thou shalt love thy neighbor as thyself,'--setting as an ascending series before those who wished to follow him, the precepts of the law, as the entrance into life; and what he then said to one, he said to all. But when the former said, 'All these have I done' (and most likely he had not kept them, for in that case the Lord would not have said to him, 'Keep the commandments'), the Lord, exposing his covetousness, said to him, 'If thou wilt be perfect, go, sell all that thou hast, and distribute to the poor; and come follow me,' promising to those who would act thus, the portion belonging to the apostles.... But he taught that they should obey the commandments which God enjoined from the beginning, and do away with their former covetousness by good works, and follow after Christ." Book iv. chap. xii. sect. 5. Irenæus certainly teaches a very different doctrine from that of Justin Martyr concerning the commandments. He believed that men must keep the commandments, in order to enter eternal life. He says further:-- "And [we must] not only abstain from evil deeds, but even from the desires after them. Now he did not teach us these things as being opposed to the law, but as fulfilling the law, and implanting in us the varied righteousness of the law. That would have been contrary to the law, if he had commanded his disciples to do anything which the law had prohibited." Book iv. chap. xiii. sect. 1. He also makes the observance of the decalogue the test of true piety. Thus he says:--
