"Whom are the 10 Commandments written to?" ... They were written to the Jews and are part of the Mosaic law.
They were
not just written to
the Jews (those who were from Judea), they were written to all mankind as I will again reveal. They were also not part of the Mosaic Law as the Mosaic Law was not included on the stone 10 Commandments AND the 10 Commandments were in existence
prior to the Mt. Sinai event, which is where the Mosaic Law of Ordinances was first given.
The massive group of people that came out of Egypt in the Exodus, said to be around 600,000 men, not counting women and children - so likely closer to
a million, were not one single blood line race of people, nor were they all, at the time, worshipers of
the God of the Bible. They were
not all Jews.
They were a mixed multitude.
Exodus 12:38
Not only were the 10 Commandments already given
prior to the dramatic events at Mt. Sinai, proven by the events that took place prior to their arrival to the mountain in chapter 16 of Exodus, (which is just
one proof that they were
not only given to Israel)
Exodus 16:4-5
Exodus 16:22-23
...but when the Commandments were finally presented by the voice of God from the mountain top of Sinai, Moses made a very revealing admission at that time.
First Moses makes note of the many
strangers (not Israel) that are present within this massive number of people he is addressing.
Deuteronomy 29:11
Then Moses speaks specifically to the blood children of Israel, emphasizing their fathers Abraham, Isaac and Jacob, telling them that God is establishing them as a people unto Himself, that He may be their God; and in a massively illuminating declaration that
powerfully corrects modern church doctrine, Moses tells them this:
"Neither with you (Israel)
only do I make this covenant and this oath; But
with him that standeth here with us this day (all strangers present) before the Lord our God,
and also with him that is not here with us this day: (all who will pledge themselves to God Almighty 'til the end of time)"
Deuteronomy 29:14-15
Anybody who studies these passages honestly, and considers Scripture
as a whole (those who actually study the entire Bible cover-to-cover), cannot possibly, in good conscience, come to the conclusion that the Bible agrees with the modern church teaching that
the 10 Commandments are only for an ancient people that are no longer relevant to Christians today.
It's right there in Scripture and no honest and diligent student of the Bible can deny it. There are also plenty of proof texts in the NT to make it undeniable that
sin (the breaking of the 10 Commandments
1 John 3:4) is still a valid consideration for Christians, which proves that the 10 Commandments are still valid as they define sin and the very righteousness of God.
