There is a great debate among Christians regarding whether or not they have to adhere to the shadows of reality referenced by the Old Testament.
The following New Testament verses Illustrate the answer.
Col 2:16 ¶ Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days:
Col 2:17 Which are a shadow of things to come; but the body is of Christ.
Heb 8:5 Who serve unto the example and shadow of heavenly things, as Moses was admonished of God when he was about to make the tabernacle: for, See, saith he, that thou make all things according to the pattern shewed to thee in the mount.
Heb 10:1 ¶ For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
Paul knew the Law better than any of us.
With regard to this topic, He compared the shadow in the Old Testament to the reality in the New Testament in the following verses–
De 25:4 Thou shalt not muzzle the ox when he treadeth out the corn.
1Co 9:9 For it is written in the law of Moses, Thou shalt not muzzle the mouth of the ox that treadeth out the corn. Doth God take care for oxen?
Heb 8:13 In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away.
Another illustration would be circumcision. This was the predominate sign of Israel’s covenant with God. Would Paul dare to assault this Old Testament precept of Jewish life and identity?
Yes.
1Co 7:19 Circumcision is nothing, and uncircumcision is nothing, but the keeping of the commandments of God.
Paul could not have said anything more offensive to natural physical Jews.
Now, does this include the exaltation of the physical nation of Israel in favor of spiritual Israel?
Yes.
Ro 9:6 ¶ Not as though the word of God hath taken none effect. For they are not all Israel, which are of Israel:
Ro 2:28 For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh 29 But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.
Is the capitulation to the natural/outward Israel concept in violation to the know/written word of God?
Yes.
