Rejoice that whatever the shadows of the Old Testament used to veil beneath the testimonies of prophets has been brought out into the open through the mystery of the Lord's passion. As a result, the various kinds of sacrifices and the different means of purification have come to a halt. Thus, the precept of circumcision, the distinction between foods, the sabbath rest, and the killing of the paschal lamb have ceased, since "the law was given through Moses, but grace and truth came through Jesus Christ."Figures came first so that their fulfillment could follow. When the reality which had been announced finally arrived, there was no longer any need for the services of heralds. Reconciliation of the human race was conducted in such a way that the salvation which comes in Christ should have been available to all generations under the same justification. Delaying this salvation was a calculated move. It had the advantage of causing those things which were believed long before they actually took place to be honored without interruption. When the strength of faith has been established in those things that do not lie open to our vision, heavenly doctrine treats us more leniently.… To help us understand more easily, we benefit from many more prophets and witnesses than former ages.
