Early Christian Documents

Having read all of Shem Tov's Matthew and realizing that it was written in the rear of a book not made for public viewing and possible was his own personal translation, it strikes an awareness
within one to consider primacy of ancient documents. There are many arguments for Greek primacy of the Christian New Testament book of Hebrews. I have to wonder though...why would an apostle write a letter to a congregation of Hebrews in the Greek language? Ever thought that thought? If you have then you are not alone. Truth can stand the crucible of fire. It is better to have a refined truth than to be sold deceptiveness. If something is a translation then it's a translation. So be it. It is not going to be discredited if it is a translation. If we felt that way we would not appreciate the Bible being given to us in the English language. Just some thoughts.
