Hegesippus appealed principally to tradition as embodied in the teaching which had been handed down through the succession of bishops, thus providing for Eusebius information about the earliest bishops that otherwise would have been lost.
Hegesippos se odvolával zejména na tradici zakotvenou v nauce, která byla předávána skrze posloupnost biskupů, čímž Eusebiovi poskytl informace o prvních biskupech, které by jinak byly ztraceny.
