THEOSISJohn Chrysostom
What existed initially? The tiara, or what does Scripture refer to it as? What follows the tiara, as if it serves as a mediator? Thus, the tiara represents the image of a vestment. Given that the bishop is the leader of the faithful, it is fitting for him, as the foremost among them, to wear the emblem of authority upon his head. The diminishment of authority is unacceptable; he who holds the emblem of authority is subject to the law. The law, in turn, stipulates that the head of the bishop should remain covered, ensuring that the congregation understands it has leadership.

Consequently, within the Church, during the ordination of bishops, the Gospel of Christ is placed upon their head, so that the one being ordained recognizes that he is receiving the true mantle of the Gospel—and acknowledges that while he is the head of all, he operates in accordance with these divine laws—that in exercising authority over all, he exists within the confines of the law—that in requiring accountability from others in all matters, he too is accountable to the law and must adhere to it. Thus, one illustrious figure from ancient times, Ignatius, who was both a priest and martyr, expressed in a letter to a fellow priest, "Let nothing be done without your consent, but also let nothing be done apart from the will of God." The placement of the Gospel upon the bishop signifies his subjection to authority. This is why Paul mentions that a woman should have a covering on her head, which symbolizes authority. Therefore, the tiara embodies this concept of authority. Upon the tiara rested a golden plate inscribed with the name of God, illustrating that the authority of God is identified by His name.
