From the Apennine Peninsula let us turn back to the Pyrenean, where the pulsation of historic life among the Jews, though gradually becoming weaker, still was stronger than in the other countries in which they were dispersed. The two branches of intellectual activity which formerly, in their palmy days, had exercised every mind--the severe study of the Talmud and the airy pursuit of the poetic muse-- had lost their predominance in the Spanish Jewries. The systematic study of the Scriptures also was no longer properly cultivated. The literary activity of this period was almost exclusively directed towards combating the intrusiveness of the church, repelling its attacks on Judaism, and withstanding its proselytizing zeal. Faithful and strong-minded Jewish thinkers held it a duty to proclaim their convictions aloud, and to admonish waverers and strengthen them. The more the preaching monks, especially apostates of the stamp of Paul de Santa Maria, Geronimo de Santa Fé, and Pedro de la Caballeria, exerted themselves to prove that the Christian Trinity was the true God of Israel, taught and typified in the Bible and the Talmud, and the more the church stretched forth its tentacles towards the Jews, straining every nerve to fold them in its fatal embrace, the more necessary was it for the synagogue to watch over its sacred trust, and guard its holy of holies from idolatrous desecration. It was especially necessary that the weaker-minded should be spared confusion in religious and doctrinal matters. Hence Jewish preachers devoted themselves more than ever to expounding the doctrine of the unity of God in their pulpits. They pointed out the essential and irreconcilable difference between the Jewish and the Christian conception of the Deity, and characterized their identification as false and impious. The time resembled that other epoch in Jewish history when Hellenized Jews tried to induce their brethren to deny God, and were supported by the secular arm. Some preachers, in their zeal, went to extremes. Instead of relying exclusively on the convincing demonstrations in the Bible text, or on the attractive illustrations of the Agada, they resorted to the armory of scholasticism, employing the formulæ of philosophy and, in the presence of the Torah, and by the side of the Hebrew prophets and the Talmudical sages, quoted Plato, Aristotle, and Averroes.
