The United Methodist Lectionary calls this Sunday Palm/Passion Sunday and offers two different sets of readings. I gather from Wiki that, in Roman Catholicism, until 1954, the name of the sixth Sunday of Lent was "Palm Sunday". In 1955, the name became, for 15 years only, "Second Sunday of the Passion or Palm Sunday". In 1970, it became "Palm Sunday of the Passion of the Lord". The sixth Sunday of Lent has thus never officially been given the exact name "Passion Sunday" and the term "Palm Sunday" is given first place in its present official name.
My practice has become to celebrate Palm Sunday in our morning services, and Passion Sunday at our evening service which marks the beginning of our Holy Week services
Palm Sunday ReadingsMark 11:1-11
As they approached Jerusalem and came to Bethphage and Bethany at the Mount of Olives, Jesus sent two of his disciples, 2 saying to them, “Go to the village ahead of you, and just as you enter it, you will find a colt tied there, which no one has ever ridden. Untie it and bring it here. 3 If anyone asks you, ‘Why are you doing this?’ say, ‘The Lord needs it and will send it back here shortly.’”
4 They went and found a colt outside in the street, tied at a doorway. As they untied it, 5 some people standing there asked, “What are you doing, untying that colt?” 6 They answered as Jesus had told them to, and the people let them go. 7 When they brought the colt to Jesus and threw their cloaks over it, he sat on it. 8 Many people spread their cloaks on the road, while others spread branches they had cut in the fields. 9 Those who went ahead and those who followed shouted,
“Blessed is he who comes in the name of the Lord!”
10 “Blessed is the coming kingdom of our father David!”
“Hosanna in the highest heaven!”
11 Jesus entered Jerusalem and went into the temple courts. He looked around at everything, but since it was already late, he went out to Bethany with the Twelve.
Psalm 118:1-2, 19-29
Give thanks to the Lord, for he is good;
his love endures forever.
2 Let Israel say:
“His love endures forever.”
19 Open for me the gates of the righteous;
I will enter and give thanks to the Lord.
20 This is the gate of the Lord
through which the righteous may enter.
21 I will give you thanks, for you answered me;
you have become my salvation.
22 The stone the builders rejected
has become the cornerstone;
23 the Lord has done this,
and it is marvelous in our eyes.
24 The Lord has done it this very day;
let us rejoice today and be glad.
25 Lord, save us!
Lord, grant us success!
26 Blessed is he who comes in the name of the Lord.
From the house of the Lord we bless you.
27 The Lord is God,
and he has made his light shine on us.
With boughs in hand, join in the festal procession
up to the horns of the altar.
28 You are my God, and I will praise you;
you are my God, and I will exalt you.
29 Give thanks to the Lord, for he is good;
his love endures forever.
Passion Sunday Readings
The Sovereign Lord has given me a well-instructed tongue,
to know the word that sustains the weary.
He wakens me morning by morning,
wakens my ear to listen like one being instructed.
5 The Sovereign Lord has opened my ears;
I have not been rebellious,
I have not turned away.
6 I offered my back to those who beat me,
my cheeks to those who pulled out my beard;
I did not hide my face
from mocking and spitting.
7 Because the Sovereign Lord helps me,
I will not be disgraced.
Therefore have I set my face like flint,
and I know I will not be put to shame.
8 He who vindicates me is near.
Who then will bring charges against me?
Let us face each other!
Who is my accuser?
Let him confront me!
9 It is the Sovereign Lord who helps me.
Who will condemn me?
They will all wear out like a garment;
the moths will eat them up.
Be merciful to me, Lord, for I am in distress;
my eyes grow weak with sorrow,
my soul and body with grief.
10 My life is consumed by anguish
and my years by groaning;
my strength fails because of my affliction,
and my bones grow weak.
11 Because of all my enemies,
I am the utter contempt of my neighbors
and an object of dread to my closest friends—
those who see me on the street flee from me.
12 I am forgotten as though I were dead;
I have become like broken pottery.
13 For I hear many whispering,
“Terror on every side!”
They conspire against me
and plot to take my life.
14 But I trust in you, Lord;
I say, “You are my God.”
15 My times are in your hands;
deliver me from the hands of my enemies,
from those who pursue me.
16 Let your face shine on your servant;
save me in your unfailing love.
5 In your relationships with one another, have the same mindset as Christ Jesus:
6 Who, being in very nature God,
did not consider equality with God something to be used to his own advantage;
7 rather, he made himself nothing
by taking the very nature of a servant,
being made in human likeness.
8 And being found in appearance as a man,
he humbled himself
by becoming obedient to death—
even death on a cross!
9 Therefore God exalted him to the highest place
and gave him the name that is above every name,
10 that at the name of Jesus every knee should bow,
in heaven and on earth and under the earth,
11 and every tongue acknowledge that Jesus Christ is Lord,
to the glory of God the Father.
