If Melchizedek literally had no father or mother, then the only person he could have been was God Himself; He is the only person with no beginning (I Tim.6:16; Ps.90:2). But this is vetoed by Heb.7:4: "Consider how great this man was", and also by the fact that he was seen by men (which God cannot be) and offered sacrifices to God. If he is called a man, then he must have had literal parents.
Ikiwa Melkizedeki kwa maneno halisi hakuwa na Baba wala mama, basi mtu pekee anaweza kuwa ni Mungu mwenyewe; ni mtu wa pekee asiye na mwanzo (1 Tim. 6: 16; Zab.90: 2). Lakini taarifa hii haikubaliani na Ebra 7: 4:"Angalieni jinsi mtu huyo alivyokuwa mkuu"na vile vile kwa ukweli wa kwamba watu walimuona (ambapo Mungu hawezi kuonwa) na alimtolea dhabihu Mungu. Ikiwa ameitwa mtu huyo, basi huyo ilimpasa kuwa na wazazi halisi.
