QUOTE : If Pulcheria were able to pose as the human embodiment of the Theotokos, in so doing she would be blurring the line between Christianity and the rituals of imperial cult, which had existed since pagan times.<br /><br />This would also raise the disturbing question, whether it was the bishop or the imperial family who had the right to define the nature of Christian piety and liturgical practice. A law of Theodosius II promulgated in 425, for example, reassures those who fail to participate in some public ceremony related to civic cult in order to attend a church service because 'due reverence is paid to the emperor when God is worshipped'. This law reveals that Christian liturgy had now taken precedence over the old civic cult, but it also shows a blurring between the person of the emperor and the person of Christ. One can see why a bishop of Constantinople might have resisted this. Nestorius may have suspected that Theodosius was using Pulcheria to draw the Church even more tightly under the control of the imperial family.
