Now you, my reader, who bear the name of Jew, take your stand upon the Law, and are, so to speak, proud of your God. You know his plan, and are able through your knowledge of the Law truly to appreciate moral values. You can, therefore, confidently look upon yourself as a guide to those who do not know the way, and as a light to those who are groping in the dark. You can instruct those who have no spiritual wisdom: you can teach those who, spiritually speaking, are only just out of the cradle. You have a certain grasp of the basis of true knowledge. You have without doubt very great advantages. But, prepared as you are to instruct others, do you ever teach yourself anything? You preach against stealing, for example, but are you sure of your own honesty? You denounce the practice of adultery, but are you sure of your own purity? You loathe idolatry, but how honest are you towards the property of heathen temples? Everyone knows how proud you are of the Law, but that means a proportionate dishonour to God when men know that you break it! Don’t you know that: ‘the very name of God is cursed among the Gentiles because of the behaviour of Jews?’ There is, you know, a verse of scripture to that effect.
If you’re brought up Jewish, don’t assume that you can lean back in the arms of your religion and take it easy, feeling smug because you’re an insider to God’s revelation, a connoisseur of the best things of God, informed on the latest doctrines! I have a special word of caution for you who are sure that you have it all together yourselves and, because you know God’s revealed Word inside and out, feel qualified to guide others through their blind alleys and dark nights and confused emotions to God. While you are guiding others, who is going to guide you? I’m quite serious. While preaching “Don’t steal!” are you going to rob people blind? Who would suspect you? The same with adultery. The same with idolatry. You can get by with almost anything if you front it with eloquent talk about God and his law. The line from Scripture, “It’s because of you Jews that the outsiders are down on God,” shows it’s an old problem that isn’t going to go away.
