eaten, neither shall you carry forth of the flesh thereof out of the house": because, to wit, on account of their haste, they could not send any gifts of it.
The stress they suffered while in Egypt was denoted by the wild lettuces. The figurative reason is evident, because the sacrifice of the paschal lamb signified the sacrifice of Christ according to 1 Cor. 5:7: "Christ our pasch is sacrificed." The blood of the lamb, which ensured deliverance from the destroyer, by being sprinkled on the ransoms, signified faith in Christ's Passion, in the hearts and on the lips of the faithful, by which same Passion we are delivered from sin and death, according to 1 Pet. 1:18: "You were . . . redeemed . . . with the precious blood . . . of a lamb unspotted." The partaking of its flesh signified the eating of Christ's body in the Sacrament; and the flesh was roasted at the fire to signify Christ's Passion or charity. And it was eaten with unleavened bread to signify the blameless life of the faithful who partake of Christ's body, according to 1 Cor. 5:8: "Let us feast . . . with the unleavened bread of sincerity and truth." The wild lettuces were added to denote repentance for sins, which is required of those who receive the body of Christ. Their loins were girt in sign of chastity: and the shoes of their feet are the examples of our dead ancestors. The staves they were to hold in their hands denoted pastoral authority: and it was commanded that the paschal lamb should be eaten in one house, i.e. in a catholic church, and not in the conventicles of heretics.
Reply Obj. 3: Some of the sacraments of the New Law had corresponding figurative sacraments in the Old Law. For Baptism, which is the sacrament of Faith, corresponds to circumcision. Hence it is written (Col. 2:11, 12): "You are circumcised . . . in the circumcision of" Our Lord Jesus "Christ: buried with Him in Baptism." In the New Law the sacrament of the Eucharist corresponds to the banquet of the paschal lamb. The sacrament of Penance in the New Law corresponds to all the purifications of the Old Law. The sacrament of Orders corresponds to the consecration of the pontiff and of the priests. To the sacrament of Confirmation, which is the sacrament of the fulness of grace, there would be no corresponding sacrament of the Old Law, because the time of fulness had not yet come, since "the Law brought no man [Vulg.: 'nothing'] to perfection" (Heb. 7:19). The same applies to the sacrament of Extreme Unction, which is an immediate preparation for entrance into glory, to which the way was not yet opened out in the Old Law, since the price had not yet been paid. Matrimony did indeed exist under the Old Law, as a function of nature, but not as the sacrament of the union of Christ with the Church, for that union was not as yet brought about. Hence under the Old Law it was allowable to give a bill of divorce, which is contrary to the nature of the sacrament.
Reply Obj. 4: As already stated, the purifications of the Old Law were ordained for the removal of impediments to the divine worship: which worship is twofold; viz. spiritual, consisting in devotion of the mind to God; and corporal, consisting in sacrifices, oblations, and so forth. Now men are hindered in the spiritual worship by sins, whereby men were said to be polluted, for instance, by idolatry, murder, adultery, or incest. From such pollutions men were purified by certain sacrifices, offered either for the whole community in general, or also for the sins of individuals; not that those carnal sacrifices had of themselves the power of expiating sin; but that they signified that expiation of sins which was to be effected by Christ, and of which those of old became partakers by protesting their faith in the Redeemer, while taking part in the figurative sacrifices.
