Despite their disbelief, the Lord preserves those who remain in blindness and keeps them until, as the apostle Paul states, all Gentiles are incorporated into the body of Christ. Once this occurs, Israel will also be included (Rom. 11:25-26). There will then exist one flock and one Shepherd (John 10:16).
The examined parimia, traditionally read on Thursday during the second week of Lent, should also be recited on the Feast of the Purification, for the vision of Isaiah described within it relates to the significance of this feast. The canon for the Purification outlines several connections: 1) In the figure of the Lord of hosts, seated high in the temple, Isaiah beheld the incarnate God, destined to appear in the Jerusalem temple on the fortieth day post His nativity. ‘When Isaiah witnessed the prototype of God elevated on His throne, encircled by angelic hosts, he lamented, “Oh, wretched man, I have seen God incarnate”’ (5th Irmos of the Canon for the Purification). 2) The throne upon which the Lord of hosts was depicted symbolizes the Mother of God cradling the Divine Child. ‘The aged seer, observing the Word held by the hands of the Mother, proclaimed, “Rejoice, O Most Holy One; you, as the throne you bear, are God who reigns in unapproachable light and peace”’ (1 Troparion of the 5th song of the Canon). 3) The tongs with which the seraphim delivered the burning coal to Isaiah represent the hands of the Mother of God, who presented the Divine Child to the elder Simeon, with the light of that coal symbolizing the illumination received by Simeon: ‘Isaiah was purged upon receiving the coal from the seraphim and cried to the Mother of God, “You have enlightened me by presenting to Him who is not born of you, as if with tongs”’ (3 Troparion of the 5th song of the Canon). 4) Isaiah experienced fear at the sight of the Lord of hosts, just as Simeon expressed to the Theotokos: ‘“You carry fire, O Pure One; I tremble to hold the Child God in my arms”’ (2 Troparion of the 5th song of the Canon).
