First Reading: 1 Cor 10:14–22
My beloved ones, avoid idolatry.
I am speaking as to sensible people;
judge for yourselves what I am saying.
The cup of blessing that we bless,
is it not a participation in the Blood of Christ?
The bread that we break,
is it not a participation in the Body of Christ?
Because the loaf of bread is one,
we, though many, are one Body,
for we all partake of the one loaf.
Look at Israel according to the flesh;
are not those who eat the sacrifices participants in the altar?
So what am I saying?
That meat sacrificed to idols is anything?
Or that an idol is anything?
No, I mean that what they sacrifice,
they sacrifice to demons, not to God,
and I do not want you to become participants with demons.
You cannot drink the cup of the Lord and also the cup of demons.
You cannot partake of the table of the Lord and of the table of demons.
Or are we provoking the Lord to jealous anger?
Are we stronger than him?
Responsorial Psalm: Ps 116:12-13, 17-18
R./ To you, Lord, I will offer a sacrifice of praise.
How shall I make a return to the Lord
for all the good he has done for me?
The cup of salvation I will take up,
and I will call upon the name of the Lord.
R./ To you, Lord, I will offer a sacrifice of praise.
To you will I offer sacrifice of thanksgiving,
and I will call upon the name of the Lord.
My vows to the Lord I will pay
in the presence of all his people.
R./ To you, Lord, I will offer a sacrifice of praise.
Gospel Reading: Lk 6:43-49
Jesus said to the crowd, "No healthy tree bears bad fruit, no poor tree bears good fruit. And each tree is known by the fruit it bears: you don't gather figs from thorns, or grapes from brambles. Similarly the good person draws good things from the good stored in the heart, and an evil person draws evil things from the evil stored in the heart. For the mouth speaks from the fullness of the heart.
Why do you call me: 'Lord! Lord!' and not do what I say? I will show you what the one who comes to me and listens to my words and acts accordingly, is like. That one is like the builder who dug deep and laid the foundations of his house on rock. The river overflowed and the stream dashed against the house, but could not carry it off because the house had been well built.
But the one who listens and does not act, is like a man who built his house on the ground without a foundation. The flood burst against it, and the house fell at once: and what a terrible disaster that was!"
