But the spirit of Saint Francis reacted even more after his death. One part of his followers insisted upon the strict rule of having no possessions at all; they treated the other part, which permitted possessions in common, as a set of worldly apostates from the master's ideals, far from the law of the gospel. And as the church authorities decided in favour of the less strict group, the spiritual party, as they called themselves, openly rebelled against the church, while the emperor, being on bad terms with the Pope, granted them his protection. From the book of Revelation they deduced that the official church was the great Babylon and the Pope the antichrist. So even this movement, started by the Bible, ended partly as a non-conformist anti-ecclesiastical undertaking. But the main part of the Franciscans, or Friars, as they are called from the Italian _frari_ (brothers), kept to the straight line of ecclesiastical discipline, and, together with the other order founded nearly at the same time by Saint Dominic the Spaniard for the special purpose of repelling heresy, they became the powerful army of the church directed against all non-conformist movements such as the Waldensians and Albigensians. Both orders made themselves at home at the universities--at this period Bologna and Paris, later Oxford and Cambridge--and soon became very influential. They had rich monasteries and great libraries, and made Bible study their favourite subject. It is a remarkable contrast between Saint Francis, who, having only one book, a New Testament, gives this away in order to help a poor widow, and the great stores of books in the convents of Saint Francis' fraternity. The saint himself did not wish his monks to possess, privately, anything, not even a Psalter, and now they owned huge Bibles and commentaries and read and studied like any scholar of the secular clergy. Saint Francis did not wish scholarship among his brethren; it was to him something worldly, opposed to the true principles of poverty. Now members of his order sat in the chairs of the universities and were among the leading teachers of the church.
