During the next two hundred years the belief became more and more general, the doctrine more and more popular; still the Church, while it tolerated both, refused to ratify either. All this time we find no particular representation of the favourite dogma in art, for until ratified by the authority of the Church, it could not properly enter into ecclesiastical decoration. We find, however, that the growing belief in the pure Conception and miraculous sanctification of the Virgin multiplied the representations of her coronation and glorification, as the only permitted expression of the popular enthusiasm on this point. For the powerful Order of the Franciscans, who were at this time and for a century afterwards the most ardent champions of the Immaculate Conception, were painted most of the pictures of the Coronation produced during the fourteenth century.
The first papal decree touching the “Immaculate Conception” as an article of faith, was promulgated in the reign of Sixtus IV., who had been a Franciscan friar, and he took the earliest opportunity of giving the solemn sanction of the Church to what had ever been the favourite dogma of his Order; but the celebration of the festival, never actually forbidden, had by this time become so usual, that the papal ordinance merely sanctioned without however rendering it obligatory. An office was composed for the festival, and in 1496 the Sorbonne declared in favour of it Still it remained a point of dispute; still there were dissentient voices, principally among the Dominican theologians; and from 1500 to 1600 we find this controversy occupying the pens of the ecclesiastics, and exciting the interest and the imagination of the people. In Spain the “Immaculate Conception of the Virgin,” owing perhaps to the popularity and power of the Franciscans in that country, had long been “the darling dogma of the Spanish Church.” Villegas, in the “Flos Sanctorum,” while admitting the modern origin of the opinion, and the silence of the Church, contended that, had this great fact been made manifest earlier and in less enlightened times, it might possibly have led to the error of worshipping the Virgin as an actual goddess. (Stirling’s Artists of Spain, p. 905.) To those who are conversant with Spanish theology and art, it may seem that the distinction drawn in theory is not very definite or perceptible in practice.
