Hospitality of Abraham
In Part 1, I discussed how the Trinity is not seen in its fullness in Genesis, and the Old Testament in general ( as God is revealed to us fully, only by the incarnation of Christ - God becoming man ). All manifestations of the deity in the Old Testament are of the Son - and the Hospitality of Abraham is a prime example of this.
God appearing to Abraham :
Then the Lord appeared to him at the oak of Mamre, as he was sitting in the tent door during the noon hour. So he lifted his eyes and looked, and behold, three men stood before him; and when he saw them, he ran from the tent door to meet them, and bowed himself to the ground and said 'O Lord, if I have now found grace in Your sight, do not pass by Your servant...' ( Genesis 18 )
This passage, consisting of three men appearing to Abraham, does not show a mere representation and symbolism of the Trinity, but rather shows us a clear manifestation of the very Word of God - Christ (accompanied by two angels). Abraham identifies one of the men as 'Lord', and this is not a phrase which would have been used as an address of respect. Even if it had been, surely he would have used the plural 'lords' to address the three men. So, it is a recognition that one of the men is far greater than the other two, and has ultimate authority. In verse 22, we see that two of the men depart, and 'Abraham stood yet before the Lord'. In addition, the grammar of the passage emphasises that Abraham is only addressing one of the three men.
This passage shows Abraham's personal experience with the Son of God, Who is accompanied by two angels. Christ is portrayed as the Lord, and God of all. 'The invisible Father, who was worshipped in the Old Testament times under the Name 'Yahweh' always reveals Himself in His dealings with humanity through His Logos. All Old Testament theophanies of Yahweh are in fact manifestations of the prereincarnate Son, for the Father always reveals Himself through the Son.' ( Fr Lawrence R. Farley )
'Your father Abraham rejoiced to see my day, and he saw it and was glad.... Most assuredly, I say to you, before Abraham was, I am' ( John 8:56-58 )
