Reading 1, Isaiah 6:1-8

1 In the year of King Uzziah's death I saw the seated on a high and lofty throne; his train filled the sanctuary.

2 Above him stood seraphs, each one with six wings: two to cover its face, two to cover its feet and two for flying;

3 and they were shouting these words to each other: Holy, holy, holy is Sabaoth. His fills the whole earth.

4 The door-posts shook at the sound of their shouting, and the was full of smoke.

5 Then I said: 'Woe is me! I am lost, for I am a of unclean lips and I live among a people of unclean lips, and my eyes have seen the King, Sabaoth.'

6 Then one of the seraphs flew to me, holding in its hand a live coal which it had taken from the altar with a pair of tongs.

7 With this it touched my mouth and said: 'Look, this has touched your lips, your guilt has been removed and your forgiven.'

8 I then heard the voice of the saying: 'Whom shall I send? Who go for us?' And I said, 'Here am I, send me.'

Responsorial Psalm, Psalms 93:1, 1-2, 5

1 Yahweh is king, robed in majesty, robed is and girded with power.

2 The world is indeed set firm, it can never be shaken; your is set firm from of old, from all you exist.

5 Your decrees stand firm, unshakeable, is the beauty of your house, Yahweh, for all to come.

Gospel, Matthew 10:24-33

24 'Disciple is not to teacher, nor slave to master.

25 It is enough for to grow to be like teacher, and slave like master. If they have called the master of the house "Beelzebul", how much more the members of his household?

26 'So do not be afraid of them. Everything now covered up be uncovered, and everything now hidden be made clear.

27 What I say to you in the dark, tell in the daylight; what you hear in whispers, proclaim from the housetops.

28 'Do not be afraid of those who kill the body but cannot kill the soul; fear him rather who can destroy both body and in hell.

29 Can you not buy two sparrows for a penny? And yet not one falls to the ground without your Father knowing.

30 Why, every hair on your head has been counted.

31 So there is no need to be afraid; you are worth more than many sparrows.

32 'So if anyone declares himself for me in the presence of human beings, I declare myself for him in the presence of my Father in heaven.

33 But the one who disowns me in the presence of human beings, I disown in the presence of my Father in heaven.
