This episode about Justus made it difficult to identify this Toletan deacon from the times of Helladius (bishop of Toledo from 615 to 633) with the successor of Helladius, bishop Justus to whom Ildefonsus devotes a laudatory chapter further in the text. Some scholars see in this episode evidence of the episcopal schism in Toledo. Others proposed that the deacon Justus was promoted to the episcopal see elsewhere, not in Toledo.
