715. Since Divine good and Divine truth are the most universal principles of everything to do with heaven and the church, this was why Melchizedek, who represented the Lord, brought out bread and wine to Abram, and blessed him. We read of Melchizedek:

Melchizedek, king of Salem, brought out to Abram bread and wine; and he was priest to God most high, and he blessed him, Genesis 14:18-19.

It is clear that Melchizedek represented the Lord from these words in the Psalms of David:

You are a priest for ever after the fashion of Melchizedek, Psalms 110:4, That this was said of the Lord may be seen in Hebrews 5:5-10; 6:20; 7:1, 10-11, 15, 17, 21. The reason why he brought out bread and wine was that these two include everything to do with heaven and the church, and so with blessing, in the same way as bread and wine do in the Holy Supper.
