In 2 Corinthians 3 Paul teaches a short discourse contrasting the glory of the Old Covenant and the glory of the New Covenant, employing the metaphor of the veil that concealed the light of Moses' face. This passage is frequently understood to imply replacement theology the cancellation of the Torah, but a closer look reveals a the role of the Torah in both old and new covenants.
But if the ministry of death, in letters engraved on stones, came with glory, so that the sons of Israel could not look intently at the face of Moses because of the glory of his face, fading as it was, how will the ministry of the Spirit fail to be even more with glory?For if the ministry of condemnation has glory, much more does the ministry of righteousness abound in glory. For indeed what had glory, in this case has no glory because of the glory that surpasses it. For if that which fades away was with glory, much more that which remains is in glory. (2 Corinthians 3:7-11)
