Responsorial Psalm Ps 50:1 and 8, 16bc-17, 20-21

R. (14a) Offer to God a sacrifice of praise.
God the LORD has spoken and summoned the earth,
from the rising of the sun to its setting.
“Not for your sacrifices do I rebuke you,
for your burnt offerings are before me always.”
R. Offer to God a sacrifice of praise.
“Why do you recite my statutes,
and profess my covenant with your mouth
Though you hate discipline
and cast my words behind you?”
R. Offer to God a sacrifice of praise.
“You sit speaking against your brother;
against your mother’s son you spread rumors.
When you do these things, shall I be deaf to it?
Or do you think that I am like yourself?
I will correct you by drawing them up before your eyes.”
R. Offer to God a sacrifice of praise.

Alleluia Jn 14:6

R. Alleluia, alleluia.
I am the way and the truth and the life, says the Lord;
no one comes to the Father except through me.
R. Alleluia, alleluia.

Gospel Mk 8:11-13

The Pharisees came forward and began to argue with Jesus,
seeking from him a sign from heaven to test him.
He sighed from the depth of his spirit and said,
“Why does this generation seek a sign?
Amen, I say to you, no sign will be given to this generation.”
Then he left them, got into the boat again,
and went off to the other shore.
