Ritual in matters of dress had rapidly been growing. Pope Celestine, who occupied the Roman See from 423 till 432, found it necessary to write a sharp letter to the Bishops of Vienne and Narbonne for 'devoting themselves rather to superstitious observances in dress than to purity of heart and faith.' Certain monks, it appears, had attained to episcopal rank, but had retained their ascetic costume. Some of Celestine's sentences are very striking in this connection; and although they refer primarily to outdoor costume, we cannot but think that, in a later age, when the regulations governing the ritual uses of vestments had been formulated, and the vestments themselves had been elaborated to their ultimate form, the force of his words would have been somewhat modified. 'By dressing in a cloak [_pallium_],' he says, 'and by girding themselves with a girdle, they think to fulfil the truth of Scripture, not in the spirit, but in the letter. For if these precepts were given to the end that they should be obeyed in this wise, why do they not likewise that which follows, and carry burning lights in their hands as well as their pastoral staves? We should be distinguished from the common people, or from all others, by our learning, not by our dress; by our habit of life, not by our clothing; by the purity of our minds, not by the cut of our garments. For if we begin to introduce novelties, we shall trample under foot the usage which our fathers have handed down to us, and give place to vain superstitions.' The fullest information on the subject of vestments during this period comes from Spain, in the oft-quoted acts of the fourth council of Toledo, which sat under the presidency of St Isidore of Seville in the year 633. Of the canons which were drawn up at this council that which is of the highest importance in this inquiry is the twenty-eighth, although it is not directly connected with vestment-usage. It provides for the case of a cleric who had been unjustly degraded from his order, and ordains that such a one, if he be found innocent in a subsequent synod, 'cannot be reinstated in his former position unless he regain his lost dignities before the altar, at the hands of a bishop. If he be a bishop, he must receive the _orarium_,[15] ring, and staff; if a priest, the _orarium_ and _planeta_; if a deacon, the _orarium_ and _alba_; if a subdeacon, the paten and chalice, and similarly for the other orders—they must receive, on their restoration, whatever they received on their ordination.'[16] On the principle which is all but universal, that the clergy of the higher orders added the insignia of the lower orders to those of their own, we are enabled by the help of this act to draw up a table of the vestments recognised in Spain, which shows at a glance the manner in which they were distributed among the different orders of clergy:
