"The greatest evil of our social life is that we know too little of the unseen realities," said Rabbi Harry Levi yesterday in his lecture on "Judaism and Law" at the seventh meeting of the series of addresses on the general subject of "Religion and Law," under the auspices of first-year law students.

"The greatest evil of our civilization," continued Rabbi Levi, "is our two kinds of law,--church and state. We ought only to have one. Years ago, when the church and the state were one, there was but a single law. This law, whether you call it ecclesiastical or secular does not matter, covered all cases and its great advantage lay in that its provisions were enforced by both the temporal and spiritual power. Now that these are separate, the secular law no longer receives the sanction of the spiritual; men say that, since the law is man-made, it can be man-broken. The separation of the church and state has involved a loss of the reverence of law."

Rabbi Levi, explaining that there could be no "static religion", denied the existence of an orthodox religion.

"There is no church," said Rabbi Levi, "that has today the same laws it had in the Middle Ages."
