Augustine of Hippo

It is not the Old Testament that is done away with in Christ but the concealing veil, so that it may be understood through Christ. That is, as it were, laid bare, which without Christ is hidden and obscure. The same apostle adds immediately: "When you shall turn to Christ, the veil shall be taken away." He does not say: "The law or the Old Testament will be taken away." It is not the case, therefore, that by the grace of the Lord that which was covered has been abolished as useless; rather the covering has been removed which concealed useful truth. This is what happens to those who earnestly and piously, not proudly and wickedly, seek the sense of the Scriptures. To them is carefully demonstrated the order of events, the reasons for words and deeds and the agreement of the Old Testament with the New, so that not a point remains where there is not complete harmony; and such secret truths are conveyed in figures. When they are brought to light by interpretation, they compel those who wished to condemn rather than to learn.
