AC 2921 - Why the Evangelists called Jehovah, Lord

AC 2921 [5, 6]

But in the Word of the New Testament,
with the Evangelists and in the Apocalypse,
"Jehovah" is nowhere named;
but instead of "Jehovah" it is said "Lord" . . ..

Among the hidden causes
of their calling Jehovah "the Lord" were the following.
If at that time it had been said
that the Lord was the Jehovah
so often named in the Old Testament,
men would not have accepted it,
for they would not have believed it;
and moreover the Lord did not become
Jehovah as to the Human also
until He had completely united
the Divine Essence to the Human Essence,
and the Human to the Divine.
The full union was accomplished
after the last temptation,
which was that of the cross;
and for this reason,
after the resurrection
the disciples always called Him "the Lord".

You call Me Master and Lord,
and you say well, for I am.
(John 13:13-14, 16)

and these words signify that He was Jehovah God;
for He is here called "Lord" as to good,
and "Master" as to truth.
