Pope Siricius (384–399) claimed for papal decretals the same binding force as decisions of synods, Pope Innocent I (401–417) said that all major judicial cases should be reserved for the see of Rome, and Pope Boniface I (418–422) declared that the church of Rome stands to "the churches throughout the world as the head to its members" and that bishops everywhere, while holding the one same episcopal office, must "recognise those to whom, for the sake of ecclesiastical discipline, they should be subject".
