The Angel of the LORD (malak YHWH) is not merely an angelic messenger but a theophanic manifestation of God the Son before His incarnation. This figure appears to Hagar and she responds, "You are a God of seeing... Truly here I have seen him who looks after me" (Genesis 16:13). He appears in the burning bush and identifies Himself: "I am the God of your father, the God of Abraham, the God of Isaac, and the God of Jacob" (Exodus 3:2, 6). He accepts worship from Joshua (Joshua 5:13-15) -- something no created angel would permit (Revelation 22:9). He appears to Manoah and his wife, and Manoah says, "We shall surely die, for we have seen God" (Judges 13:22). The Angel of the LORD is distinct from the Father (He is sent by the LORD) yet is Himself the LORD -- perfectly consistent with the pre-incarnate Son.
Webster 1828 does not contain a combined entry for "Angel of the Lord."
Under ANGEL, Webster writes: "A spirit, or a spiritual being, employed by God to communicate his will to man." The particular theological significance of "the Angel of the LORD" as a Christophany was well established in Reformed theology by Webster's era but was treated as a doctrinal matter rather than a lexical one.
• Genesis 16:7, 13 — "The angel of the LORD found her... She called the name of the LORD who spoke to her, 'You are a God of seeing.'"
• Exodus 3:2, 6 — "And the angel of the LORD appeared to Him in a flame of fire... 'I am the God of your father.'"
• Joshua 5:13-15 — "The commander of the army of the LORD said to Joshua, 'Take off your sandals from your feet, for the place where you are standing is holy.'"
• Judges 13:18, 22 — "The angel of the LORD said, 'Why do you ask my name, seeing it is wonderful?'... 'We shall surely die, for we have seen God.'"
• Genesis 22:11-12 — "The angel of the LORD called to Him... 'Now I know that you fear God, seeing you have not withheld your son, your only son, from me.'"
The Angel of the LORD has been reduced to a mere angel or dismissed as a literary device.
Liberal scholarship treats the Angel of the LORD as a literary device, a narrative technique by which ancient Israelites described encounters with the divine without violating the prohibition against seeing God directly. This dismisses the theological content of the texts themselves. The Angel speaks as God, is identified as God, receives worship due to God alone, and exercises divine prerogatives. Reducing this figure to a literary convention empties the Old Testament of its Christological witness. The Reformed tradition has rightly recognized these appearances as the pre-incarnate Son making Himself known to His people -- the same Lord who would later take on flesh in the fullness of time.
• "The Angel of the LORD is no ordinary angel -- He speaks as God, receives worship, and is identified as God by those who encounter Him."
• "When the Angel of the LORD tells Abraham 'you have not withheld your son from me,' He identifies Himself as the God to whom Isaac was being offered."
