I am intrigued by the character Melchizedek, named only in Genesis 14, Psalm 110, and the letter to the Hebrews, chapters 5, 6, and 7. Melchizedek is a type of Jesus. Jesus is his anti-type.
Typology is the study of person, events, or symbols that foreshadow things to come. In the Bible, a “type” often refers to an Old Testament figure who “typifies” or finds its fulfillment in Christ. For example, in Romans 5.14 NAS Paul called Adam a “type of Him [Jesus] who was to come.” In this example Adam is the “type” and Jesus is the “antitype.”
To further illustrate, Noah’s ark and the flood is a “type” for which baptism is the “antitype.” See 1st Peter 3.20-21.
