Over the years I have come to suspect it most likely was in Hebrew, at least the Gospels and Revelation.
The most compelling impetus to my leaning in this direction is the fact that Hebrew was the language of the Temple in Jerusalem, ergo anyone speaking in another language about anything concerning Yahweh, God, would be looked upon as a
blasphemer.
Although it is said the lingua franca at the time of our Savior's advent was Aramaic, it would have been frowned upon to use that languaage in teaching anyting to dow with Ultimate Truth from God, Yahweh.
It really is not terribly important at all levels, but it is in undetanding much of what references are made to the Old Testament.
One amazingly informative example is how when the Old Testament prophets are quoted, each time the word, Lord, in reference to God is use, it is taken from Yahweh. I find that interesting, and lovely at the same time.
RAbbinical teaaching states Yahweh should not be said out loud, instead they say you should say HaShem which means the name.
From what I have deriv ed from their own writings, the name Yahweh is to wonderful not to be proclaimed around the world to all nations. Not necessarily as YIahweh, but as it means Self-existing, it is like saying the I Am, am being transitive as only one who is Self-Existing may use in honesty, forno creature can say I Am, a creature may say I am created.
Therfor Yahweh is not some mysterous name too holy to be pronounced, it is His Fame. We will know His true name come the Kingdom when He returns to the peoplles and nations a pure tongue so we may all call on Him by one name Zephaniah. Please, do not get me going.
Know that all who are led by the Holy Spirit do not deeply concern themselves with linguistics, and they have no need to do so, it is just apersonal passion of my own. God bless you Dan Daniel......God is judge from the Hebrew...
JaumeJ, is it your understanding that the nt was originally written in Hebrew?
