231. In this freedom from the bondage of tradition Jesus was not alone. John the Baptist's message had been as simple and unsupported by appeal to the elders. Jesus and John both revived the method of the older prophets, and it is in large measure due to this that the people distinguished them clearly from their ordinary teachers, and held them both to be prophets. One thing involved in this authoritative method was a frank appeal to the conscience of men. So completely had the scribes substituted memory of tradition for appeal to the simple sense of right, that they were utterly dazed when Jesus undertook to settle questions of Sabbath observance and ceremonial cleanliness by asking his hearers to use their religious common sense, and consider whether a man is not much better than a sheep, or whether a man is not defiled rather by what comes out of his mouth than by what enters into it (Matt. xii. 12; Mark vii. 15). Jesus was for his generation the great discoverer of the conscience, and for all time the champion of its dignity against finespun theory and traditional practice. All his teaching has this quality in greater or less degree. It appears when by means of the parable of the Good Samaritan he makes the lawyer answer his own question (Luke x. 25-37), when he bids the multitude in Jerusalem "judge not according to the appearance, but judge righteous judgment" (John vii. 24), when he asks his inquisitors in the temple whose image and superscription the coin they used in common business bears (Mark xii. 16). His whole work in Galilee was proof of his confidence that in earnest souls the conscience would be his ally, and that he could impress himself on them far more indelibly than any sign from heaven could enforce his claim.
