Fourthly, an altar is reconsecrated, if to it or to the conjunction of the table with the under structure so great an enlargement be made as that it loseth its original form, since the form giveth the existence to the thing. Yet it doth not become profaned on account of a trifling enlargement: but in that case the sacred part draweth over to itself the part not sanctified: so long as the conjunction of the top slab and under structure be not greatly changed. Fifthly, an altar, just as a church, is reconsecrated in cases of doubt. Sixthly, a travelling altar, if the stone be removed from the wood in which it is inserted, which in some sort representeth its _seal_, and be replaced again in the same or in other wood, some think should be reconsecrated, but others only reconciled. But although it be often by the command of the bishop transferred from place to place, and carried on a journey (on which account it is called a portable or a travelling altar) yet it is not reconsecrated in consequence of this, nor yet reconciled. 36. But if a consecrated chalice be regilt, is it therefore to be reconsecrated? It seemeth so, since it appeareth to become a new chalice. For he who doth renew the old fashion of a work seemeth to make a new work: and he doth remake, who doth mend a thing already made. And assuredly consecration doth pertain to the outer surface. And hence it is that I have said above that a church, if its walls be stripped of their outer coat, must be reconsecrated. 37. The converse is nevertheless true, that neither on account of whitewashing or painting the walls, nor of any small addition to them, is a church to be reconsecrated; as I have already said. Wherefore, if the shape of the chalice be not changed, it remaineth the same chalice, and is not to be reconsecrated; just as also a church being repaired, since it remaineth the same church, is not to be reconsecrated, as aforesaid. {107} But if the former shape be changed, the case were otherwise, since, as I have said, the shape giveth existence to the thing. Nevertheless, it is decent, as well by reason of its contact with unclean hands as also of the increment of unconsecrated matter, that a chalice, being regilded, should be washed with exorcised water before that the most Holy Body and Blood of the Lord be sacrificed therein. Let us now say something about Reconciliation. 38. Upon this head it is to be noted that the spiritual temple, which is man, is ofttimes polluted. Whence we do read in the twentieth of Leviticus what men be polluted, and how they may not enter the church until they be washed with water and cleansed: as also in the nineteenth of Numbers, 'He that toucheth the dead body of a man shall be unclean .... wherefore he shall purify himself and wash his clothes and bathe himself in water and shall be clean.' And the Prophet saith, 'Thou shalt purge me with hyssop and I shall be clean. [Footnote 405] [Footnote 405: Psalm li (_Miserere mei_), 7.]
