Spain paid little attention to the theological controversy over Jansen, though his works and those of his followers were duly condemned by the Inquisition.[584] It is a curious illustration of this indifference that when the great bibliographer, Nicolás Antonio, in defending Prudentius against the attack of Hincmar of Reims, pronounced as good Catholic doctrine the assertion of Prudentius that the blood of Christ was shed only for believers and not for unbelievers, this, which is virtually the same as the fifth of the condemned propositions of Jansen, escaped attention. The book was printed in Rome at the expense of Cardinal Aguirre; the Spanish Inquisition took no note of it in the Indexes of 1707 and 1747 and the passage is retained in the edition of 1788, produced under the auspices of Carlos III.[585] Yet Spain could not keep wholly out of the quarrel, for its Flemish provinces were a hot-bed of Jansenism which could not be eradicated from the University of Louvain. In 1649 Doctor Rescht, as the representative of the University and of its great protector Engelbert Dubois, Archbishop of Malines, came to Madrid, where he printed and circulated a memorial against the bull of Urban VIII and the Archduke Leopold so insulting to both that the Inquisition suppressed it, by a decree of September 13, 1650.[586] This did not cool the ardor of the Flemish followers of Jansen and, in 1656, Alexander VII felt obliged to address Don John of Austria, then Governor of the Low Countries, with an urgent exhortation to suppress the propagation of the condemned errors.[587]
