Unlocking the Meaning of Isaiah 53: Who is the Suffering Servant? by Jonathan McLatchie

The following is a link to McLatchie's excellent article that succinctly gathers together the Old Testament evidence that the angel of God's presence, the angel of the LORD (malak YHVH), the arm of the LORD, the messenger/angel of the Covenant, the angel in whom God's name resides (etc.) are all one person, namely the pre-incarnate Messiah/Christ.

I myself have written or linked to and/or reproduced other people's work that demonstrate the same thing on this Blog. But this article by McLatchie is an excellent summation of that data. I highly recommend it.
