Eucharistic meditation

Just as at one time circumcision, in so far as it had to do with effecting the remission of sins, took the place of baptism, and the Red Sea presented a likeness and figure of the same, so the paschal lamb lamb, whose flesh was eaten by the people and by whose blood the posts of the houses were marked, preceded in the figure of of the sacrament of the body of Christ. …

Finally we eat the flesh of the lamb when by taking His true body in the sacrament we are incorporated with Christ through faith and love. Elsewhere what is eaten is incorporated. Now when the body of Christ is eaten, not what is eaten but he who eats is incorporated with Him whom He eats. On this account Christ wished to be eaten by us, that He might incorporate us with Him. This is the sacrament of the body of Christ and the substance of the sacrament of the body of Christ.
