Reading 1 Joel 2:12-18

Even now, says the LORD,
return to me with your whole heart,
with fasting, and weeping, and mourning;
Rend your hearts, not your garments,
and return to the LORD, your God.
For gracious and merciful is he,
slow to anger, rich in kindness,
and relenting in punishment.
Perhaps he will again relent
and leave behind him a blessing,
Offerings and libations
for the LORD, your God.

Blow the trumpet in Zion!
proclaim a fast,
call an assembly;
Gather the people,
notify the congregation;
Assemble the elders,
gather the children
and the infants at the breast;
Let the bridegroom quit his room
and the bride her chamber.
Between the porch and the altar
let the priests, the ministers of the LORD, weep,
And say, “Spare, O LORD, your people,
and make not your heritage a reproach,
with the nations ruling over them!
Why should they say among the peoples,
‘Where is their God?'”

Then the LORD was stirred to concern for his land
and took pity on his people.

Responsorial Psalm Psalm 51:3-4, 5-6ab, 12-13, 14 and 17

R. (see 3a)  Be merciful, O Lord, for we have sinned.
Have mercy on me, O God, in your goodness;
in the greatness of your compassion wipe out my offense.
Thoroughly wash me from my guilt
and of my sin cleanse me.
R. Be merciful, O Lord, for we have sinned.
For I acknowledge my offense,
and my sin is before me always:
“Against you only have I sinned,
and done what is evil in your sight.”
R. Be merciful, O Lord, for we have sinned.
A clean heart create for me, O God,
and a steadfast spirit renew within me.
Cast me not out from your presence,
and your Holy Spirit take not from me.
R. Be merciful, O Lord, for we have sinned.
Give me back the joy of your salvation,
and a willing spirit sustain in me.
O Lord, open my lips,
and my mouth shall proclaim your praise.
R. Be merciful, O Lord, for we have sinned.

Reading 2 2 Corinthians 5:20—6:2

Brothers and sisters:
We are ambassadors for Christ,
as if God were appealing through us.
We implore you on behalf of Christ,
be reconciled to God.
For our sake he made him to be sin who did not know sin,
so that we might become the righteousness of God in him.

Working together, then,
we appeal to you not to receive the grace of God in vain.
For he says:

In an acceptable time I heard you,
and on the day of salvation I helped you.

Behold,…
