rite, moreover, three liquids were employed: viz. blood, against the corruption of the blood; oil, to denote the healing of the disease; and living waters, to wash away the filth.
The figurative reason was that the Divine and human natures in Christ were denoted by the two sparrows, one of which, in likeness of His human nature, was offered up in an earthen vessel over living waters, because the waters of Baptism are sanctified by Christ's Passion. The other sparrow, in token of His impassible Godhead, remained living, because the Godhead cannot die: hence it flew away, for the Godhead could not be encompassed by the Passion. Now this living sparrow, together with the cedar-wood and scarlet or cochineal, and hyssop, i.e. faith, hope and charity, as stated above (ad 5), was put into the water for the purpose of sprinkling, because we are baptized in the faith of the God-Man. By the waters of Baptism or of his tears man washes his clothes, i.e. his works, and all his hair, i.e. his thoughts. The tip of the right ear of the man to be cleansed is moistened with some the blood and oil, in order to strengthen his hearing against harmful words; and the thumb and toe of his right hand and foot are moistened that his deeds may be holy. Other matters pertaining to this purification, or to that also of any other uncleannesses, call for no special remark, beyond what applies to other sacrifices, whether for sins or for trespasses.
Reply Obj. 8 and 9: Just as the people were initiated by circumcision to the divine worship, so were the ministers by some special purification or consecration: wherefore they are commanded to be separated from other men, as being specially deputed, rather than others, to the ministry of the divine worship. And all that was done touching them in their consecration or institution, was with a view to show that they were in possession of a prerogative of purity, power and dignity. Hence three things were done in the institution of ministers: for first, they were purified; secondly, they were adorned [*'Ornabantur.' Some editions have 'ordinabantur'--'were ordained': the former reading is a reference to Lev. 8:7-9] and consecrated; thirdly, they were employed in the ministry. All in general used to be purified by washing in water, and by certain sacrifices; but the Levites in particular shaved all the hair of their bodies, as stated in Lev. 8 (cf. Num. 8).
