The Petrine privilege per the Code of Canon Law being


  Code of Canon Law Can.  1142 For a just cause, the Roman
  Pontiff can dissolve a non-consummated marriage between baptized
  persons or between a baptized party and a non-baptized party at the
  request of both parties or of one of them, even if the other party is
  unwilling.
No.

Petrine privilege and all the customs around it grew out of the practical administration of the sacraments over time.  There is nothing in the scripture recognized as the canonized New Testament that speaks directly to any of this.  If anything all of this can be said to have grown out of Jesus admonition not to divorce - Matthew 19:1-12.
