Not true.
For this commandment which I command you today is not too difficult for you, nor is it out of reach. "It is not in heaven, that you should say, '(C)Who will go up to heaven for us to get it for us and make us hear it, that we may observe it?' "Nor is it beyond the sea, that you should say, 'Who will cross the sea for us to get it for us and make us hear it, that we may observe it?' "But the word is very near you, in your mouth and in your heart, that you may observe it. (Deu. 30:11-14 NASB)
This is a great text, but I think it is a mistake to apply it to support the keeping of the Law of Moses.
First, we should note that the "what" that is being commanded here is not necessarily
the Law of Moses. It could be the Law of Moses, but it could be, and I suggest that it is indeed, something
else.
This is why it is so critical to look at the
entire Biblical narrative and not come to such a text,
presuming that it is talking about keeping the
Law of Moses in particular. And while I will not give the whole story here, I suggest that the following is the proper interpretation of this famous passage:
1. This passage appears in an overall prophetic treatment by Moses (assuming he is the author of Deuteronomy) of how the covenant narrative will unfold. And in this text, in particular, it is clear that Moses is talking about what will happen at covenant
renewal. So we should apply this text only in a context where we believe that the covenant has been renewed.
2. The Biblical narrative shows us quite clearly that covenant renewal happens at the
Cross.
3. However, based on the teaching of Paul (Romans, Ephesians, Galatians, Colossians),
and the actions of Jesus (such as His declaration, against the Law of Moses, that
all foods are clean), it is clear that the Law of Moses, as a written code, has been
retired at covenant renewal.
4. However, as per Romans 3:31, Romans 2, Romans 10, and Jesus summarizing of the Law of Moses, we know that, while the Law of Moses has come to an end, there is still a "law" that persists. We can talk about what this is, but one thing is clear - it is
not the Law of Moses.
5. The renewal of the covenant, again following many Old Testament texts, involves the ingathering of the
Gentiles. So since the Law of Moses was given to
Jews only (as established by a separate argument), it would be very odd indeed if the covenant renewal text given to us in Deuteronomy 30 is talking about obeying commands that are part of a law - the Law of Moses - that only
Jews are under.
6. So, given that covenant renewal involves the replacement of the Law of Moses with this mysterious new law, we can be quite confident that what Moses is talking about in Deuteronomy 30 is not the Law of Moses, but this mysterious new law, a law that, unlike the Law of Moses,
Gentiles can indeed keep.
