Q. The LORD appeared to Abraham in Gen 18. Are the three men the 3 persons of the Trinity? If yes, shouldn’t this be the First Coming of Christ?
A. No, the spokesperson whom Abraham bargained with was the Lord. The other two were angels according to Gen 19:1 “The two angels arrived at Sodom …” This is a case of theophany or a manifestation of God to man, often but not always in human form. Examples include:
* Gen 12:7 The LORD appeared to Abram and said …
* Gen 17:1 When Abram was ninety-nine years old, the LORD appeared to him and said …
* Gen 26:, 242 The LORD appeared to Isaac and said …
* Gen 32:30 So Jacob called the place Peniel, saying, “It is because I saw God face to face …
* Gen 35:9 After Jacob returned from Paddan Aram, God appeared to him again and blessed him.
* Ex 3:2 There the angel of the LORD appeared to him in flames of fire from within a bush.
* Ex 4:5 “This,” said the LORD, “is so that they may believe that the LORD, the God of their fathers–* the God of Abraham, the God of Isaac and the God of Jacob–has appeared to you.”
* Ex 24:9-10 Moses and Aaron, Nadab and Abihu, and the seventy elders of Israel went up and saw the God of Israel.
* 1 Kings 3:5 At Gibeon the LORD appeared to Solomon … 2 Chron 1:7
* 1 Kings 9:2 the LORD appeared to him a second time… 2 Chron 7:12
Some commentators believe the “angel of the Lord” is not an ordinary angel, but the pre-incarnate Christ Himself. The “glory of the Lord” is theophany but not in human form e.g. Lev 9:23; Num 14:10, 16:19, 42, 20:10. So is the “pillar of cloud” e.g. Deut 31:15.
Since Jesus Himself said in Jn 6:46 No one has seen the Father except the one who is from God; only He has seen the Father, some scholars believe the theophanies are in fact Christophanies or pre-incarnate appearances of Christ, not the Father. Technically, the First Coming of Christ refers to His incarnation, not Christophanies in the OT.
