Whether the matter of this sacrament need be consecrated by a bishop?

❌ Objection 1 : It would seem that the matter of this sacrament need not be consecrated by a bishop. Because the consecration of the Eucharistic elements surpasses that of the matter in this sacrament. But a priest can consecrate the matter in the Eucharist. Therefore he can do so in this sacrament also.

❌ Objection 2 : Further, in material works the higher art never prepares the matter for the lower, because the art which applies the matter is more excellent than that which prepares it, as stated in Phys. ii, text. 25. Now a bishop is above a priest. Therefore he does not prepare the matter of a sacrament which is applied by a priest. But a priest dispenses this sacrament, as we shall state further on (Question [31]). Therefore the consecration of the matter does not belong to a bishop.
