In today's first reading, Isaiah 6: 1-2a, 3-9, Isaiah shares a vision he was given of "the Lord seated on a high and lofty throne, with the train of his garment filling the temple. Seraphim were stationed above. they cried out one to the other, 'Holy, holy, holy is the Lord of hours! All the earth is filled with his glory!'" Isaiah tells us that at the sound of the angels praising the Lord, the "frame of the door shook and rage house was filled with smoke." Isaiah is fearful that he is doomed, for, he says: I am a man of unclean lips, living among a people of unclean lips; yearly eyes have seen the King, the Lord of hosts!" An angel flew to him and touched his lips with an ember, saying: "See, now that this has touched your lips, your wickedness is removed, your sin purged." A voice then says ask Isaiah: "'Whom shall I send? Who will go for us?' 'Here I am,' Isaiah said, 'send me!'"
That Scripture passage is about us. We may not, with out naked eyes, see the Lord of hosts, but we do with eyes of faith. We know by faith that God is a holy God and we are men and women inclined to sin. Our lips are unclean when we engage in acts of selfishness, greed and, yes, sometimes wickedness against one another! Yes, too, to the fact that we have been purged of our wickedness, our sins, by the Blood of Jesus poured out for us on the cross and given to us in Holy Communion and in our repentance of our sins on a daily basis when we acknowledge our sinfulness in prayer, in regular confession and at every liturgy! Like with Isaiah, we, too, hear God's voice, asking "Whom shall I send? wobble will for us [the Blessed Trinity]? In word and deed, how do we answer?
