The scene that follows the announcement ‘holy, holy, holy’ is dramatic: ‘the foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke’. Isaiah’s response is not worship, as we might expect. Instead, he exclaims, ‘Woe is me!’ Seeing the holiness of the Lord makes Isaiah aware of his own lack of holiness, and fearful: ‘a man of unclean lips’ should not (he thinks) behold ‘the King, the Lord of hosts’. God’s glory shows up all that is unworthy about us. Similarly Peter, in the gospel reading from a few weeks ago, responds to the miraculous catch of fish: ‘Depart from me, O Lord, for I am a sinful man’. Beholding the greatness of the Lord brings about a new, and unsettling, revelation of our own lack of sanctity. The response from on high is not judgement, however, but comfort. One of the seraphim brings a burning coal from the altar, touches Isaiah’s lips with it, and announces, ‘Behold…your guilt has been taken away, and your sin forgiven’. Likewise Jesus reassures Peter (in the same words the angel used to put Mary at ease): ‘Do not be afraid.’
Contemplating the holiness of God ought to make us mindful of the ways we have sinned and fallen short of the glory of God. This is not the way into condemnation, though, but the door to forgiveness and new life. For both Isaiah and Peter, the recognition of his own unworthiness marks the beginning of a career (if we may call it that) in the service of God. Isaiah accepts the invitation to take God’s word to the people of Israel, and Peter becomes that rock on which the Church is built. Our own careers of discipleship may be less dramatic, but God nevertheless promises to draw us near and involve us in the real drama—the drama of our redemption and that of the whole world. We need not ask whether we are worthy; we need only allow God to make us so.
