The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Sunday, 2020-08-30:
jer 20:7-9
You duped me, O LORD, and I let myself be duped;
you were too strong for me, and you triumphed.
All the day I am an object of laughter;
everyone mocks me.
Whenever I speak, I must cry out,
violence and outrage is my message;
the word of the LORD has brought me
derision and reproach all the day.
I say to myself, I will not mention him,
I will speak in his name no more.
But then it becomes like fire burning in my heart,
imprisoned in my bones;
I grow weary holding it in, I cannot endure it.
ps 63:2, 3-4, 5-6, 8-9
R/ (2b)
My soul is thirsting for you, O Lord my God.
O God, you are my God whom I seek;
for you my flesh pines and my soul thirsts
like the earth, parched, lifeless and without water.
R/
My soul is thirsting for you, O Lord my God.
Thus have I gazed toward you in the sanctuary
to see your power and your glory,
For your kindness is a greater good than life;
my lips shall glorify you.
R/
My soul is thirsting for you, O Lord my God.
Thus will I bless you while I live;
lifting up my hands, I will call upon your name.
As with the riches of a banquet shall my soul be satisfied,
and with exultant lips my mouth shall praise you.
R/
My soul is thirsting for you, O Lord my God.
You are my help,
and in the shadow of your wings I shout for joy.
My soul clings fast to you;
your right hand upholds me.
R/
My soul is thirsting for you, O Lord my God.
rom 12:1-2
I urge you, brothers and sisters, by the mercies of God,
to offer your bodies as a living sacrifice,
holy and pleasing to God, your spiritual worship.
Do not conform yourselves to this age
but be transformed by the renewal of your mind,
that you may discern what is the will of God,
what is good and pleasing and perfect.
mt 16:21-27
Jesus began to show his disciples
that he must go to Jerusalem and suffer greatly
from the elders, the chief priests, and the scribes,
and be killed and on the third day be raised.
Then Peter took Jesus aside and began to rebuke him,
"God forbid, Lord! No such thing shall ever happen to you."
He turned and said to Peter,
"Get behind me, Satan! You are an obstacle to me.
You are thinking not as God does, but as human beings do."
Then Jesus said to his disciples,
"Whoever wishes to come after me must deny himself,
take up his cross, and follow me.
For whoever wishes to save his life will lose it,
but whoever loses his life for my sake will find it.
What profit would there be for one to gain the whole world
and forfeit his life?
Or what can one give in exchange for his life?
For the Son of Man will come with his angels in his Father’s glory,
and then he will repay all according to his conduct."
