From BeDuhn:
comparison with Matthew to establish the text of Q, all of these
problems evaporate at a stroke. Q would open with the Sermon
on the Mount/Plain material. ... The evidence of the
Evangelion, therefore, points to a Q that more consistently takes the
familiar form of a sayings collection than does the text of Q reconstructed
on the basis of Luke.
Correct, and not only is the overlap with *Ev more of a sayings document, but those sayings are highly Marcionite in nature!

Here is much of the sayings from Q. Yellow = Marcionite in character, Blue = neutral, Red = non-Marcionite.
The Beatitudes
Jesus said: 'Blessed are the poor in spirit, for theirs is the kingdom of heaven. Blessed are those who mourn, for they shall be comforted. Blessed are the meek, for they shall inherit the earth.Blessed are those who hunger and thirst for righteousness, for they shall be filled. Blessed are the merciful, for they shall obtain mercy. Blessed are the pure in heart, for they shall see God. Blessed are the peacemakers, for they shall be called sons of God. Blessed are those who are persecuted for righteousness' sake, for theirs is the kingdom of heaven. Blessed are you when they revile and persecute you, and say all kinds of evil against you falsely for my sake. Rejoice and be exceedingly glad, for great is your reward in heaven, for so they persecuted the prophets who were before you.'
5.3-12
6.27-36
Love your enemies
Jesus said: 'You have heard that it was said, You shall love your neighbor and hate your enemy. But I say to you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who spitefully use you and persecute you, that you may be sons of your Father in heaven; for He makes His sun rise on the evil and on the good, and sends rain on the just and on the unjust. For if you love those who love you, what reward have you? Do not even the tax collectors do the same? And if you greet your brethren only, what do you do more than others? Do not even the tax collectors do so? Therefore you shall be perfect, just as your Father in heaven is perfect.'
5.43-48
6.37-42
Judging others
Jesus said: 'Judge not, that you be not judged. For with what judgment you judge, you will be judged; and with the measure you use, it will be measured back to you. And why do you look at the speck in your brother's eye, but do not consider the plank in your own eye? Or how can you say to your brother, "Let me remove the speck from your eye"; and look, a plank is in your own eye? Hypocrite! First remove the plank from your own eye, and then you will see clearly to remove the speck from your brother's eye.'
7.1-5
6.43-45
The tree and its fruits
Jesus said: 'Even so, every good tree bears good fruit, but a bad tree bears bad fruit. A good tree cannot bear bad fruit, nor can a bad tree bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. Therefore by their fruits you will know them.'
7.17-20
6.47-49
The wise and foolish builders
Jesus said: 'Therefore whoever hears these sayings of mine, and does them, I will liken him to a wise man who built his house on the rock: and the rain descended, the floods came, and the winds blew and beat on that house; and it did not fall, for it was founded on the rock. But everyone who hears these sayings of mine, and does not do them, will be like a foolish man who built his house on the sand: and the rain descended, the floods came, and the winds blew and beat on that house; and it fell. And great was its fall.'
10.13-15
Woe on unrepentant cities
Jesus said: 'Woe to you, Chorazin! Woe to you, Bethsaida! For if the mighty works which were done in you had been done in Tyre and Sidon, they would have repented long ago in sackcloth and ashes. But I say to you, it will be more tolerable for Tyre and Sidon in the day of judgment than for you.
And you, Capernaum, who are exalted to heaven, will be brought down to Hades; for if the mighty works which were done in you had been done in Sodom, it would have remained until this day.'
11.21-23
He who receives you receives me
10.16
'He who receives you receives me, and he who receives me receives Him who sent me.'
10.40
10.21-22
Hidden things revealed to children
Jesus said: 'I thank You, Father, Lord of heaven and earth, that You have hidden these things from the wise and prudent and have revealed them to babes. Even so, Father, for so it seemed good in Your sight. All things have been delivered to me by my Father, and no one knows the Son except the Father. Nor does anyone know the Father except the Son, and the one to whom the Son wills to reveal Him.'
11.25-27
10.23-24
Then he turned to his disciples and said: 'But blessed are your eyes for they see, and your ears for they hear; for assuredly, I say to you that many prophets and righteous men desired to see what you see, and did not see it, and to hear what you hear, and did not hear it.'
13.16-17
11.2-4
The Lord's prayer
Jesus' disciples asked him how to pray, and he said to them: 'In this manner, therefore, pray: Our Father in heaven, hallowed be Your name. Your kingdom come. Your will be done on earth as it is in heaven. Give us this day our daily bread, and forgive us our debts, as we forgive our debtors. And do not lead us into temptation, but deliver us from the evil one.'
6.9-13a
11.9-13
Ask, seek, knock
Jesus said: 'Ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you. For everyone who asks receives, and he who seeks finds, and to him who knocks it will be opened. Or what man is there among you who, if his son asks for bread, will give him a stone? Or if he asks for a fish, will he give him a serpent? If you then, being evil, know how to give good gifts to your children, how much more will your Father who is in heaven give good things to those who ask Him!'
11.39-40
Woe to the Pharisees
Jesus said: 'Woe to you, scribes and Pharisees, hypocrites! For you cleanse the outside of the cup and dish, but inside they are full of extortion and self-indulgence. Blind Pharisee, first cleanse the inside of the cup and dish, that the outside of them may be clean also.'
23.25-26
11.43
'You love the best places at feasts, the best seats in the synagogues, greetings in the marketplaces, and to be called by men, "Rabbi, rabbi".'
23.6-7
11.46
'You bind heavy burdens, hard to bear, and lay them on men's shoulders; but you yourselves will not move them with one of their fingers.'
23.4
11.47-48
'Woe to you, scribes and Pharisees, hypocrites! Because you build the tombs of the prophets and adorn the monuments of the righteous...'
23.29
11.49-51
'...God sends you prophets, wise men, and scribes: but some of them you will kill and crucify, and some of them you will scourge in your synagogues and persecute from city to city, that on you may come all the righteous blood shed on the earth, from the blood of righteous Abel to the blood of Zechariah, son of Berechiah, whom you murdered between the temple and the altar. Assuredly, I say to you, all these things will come upon this generation.'
23.34-36
12.2-9
Warnings and encouragement
Jesus said: 'Do not fear. For there is nothing covered that will not be revealed, and hidden that will not be known. Whatever I tell you in the dark, speak in the light; and what you hear in the ear, preach on the housetops.'
And do not fear those who kill the body but cannot kill the soul. But rather fear Him who is able to destroy both soul and body in hell. Are not two sparrows sold for a copper coin? And not one of them falls to the ground apart from your Father's will. But the very hairs of your head are all numbered. Do not fear therefore; you are of more value than many sparrows.
Therefore whoever confesses me before men, him I will also confess before my Father Who is in heaven. But whoever denies me before men, him I will also deny before my Father Who is in heaven.'
10.26-33
Holy Spirit
12.10
'Anyone who speaks a word against the Son of Man, it will be forgiven him; but whoever speaks against the Holy Spirit, it will not be forgiven him, either in this age or in the age to come.'
12.32
Spirit of your Father
12.11-12
'And when they deliver you up, do not worry about how or what you should speak. For it will be given to you in that hour what you should speak; for it is not you who speak, but the Spirit of your Father who speaks in you.'
10.19-20
Do not worry
12.22-31
And he said to the disciples: 'Therefore I say to you, do not worry about your life, what you will eat or what you will drink; nor about your body, what you will put on. Is not life more than food and the body more than clothing? Look at the birds of the air, for they neither sow nor reap nor gather into barns; yet your heavenly Father feeds them. Are you not of more value than they? Which of you by worrying can add one cubit to his stature? So why do you worry about clothing? Consider the lilies of the field, how they grow: they neither toil nor spin; and yet I say to you that even Solomon in all his glory was not arrayed like one of these. Now if God so clothes the grass of the field, which today is, and tomorrow is thrown into the oven, will He not much more clothe you, O you of little faith? Therefore do not worry, saying, "What shall we eat?" or "What shall we drink?" or "What shall we wear?" For after all these things the Gentiles seek. For your heavenly Father knows that you need all these things. But seek first the kingdom of God and His righteousness, and all these things shall be added to you.'
6.25-33
Treasure in heaven
12.33-34
'Do not lay up for yourselves treasures on earth, where moth and rust destroy and where thieves break in and steal; but lay up for yourselves treasures in heaven, where neither moth nor rust destroys and where thieves do not break in and steal. For where your treasure is, there your heart will be also.'
6.19-21
12.39-40,
42-46
The coming of the Son of Man
Jesus said: 'Know this, that if the master of the house had known what hour the thief would come, he would have watched and not allowed his house to be broken into. "Therefore you also be ready, for the Son of Man is coming at an hour you do not expect.
Who then is a faithful and wise servant, whom his master made ruler over his household, to give them food in due season? Blessed is that servant whom his master, when he comes, will find so doing. Assuredly, I say to you that he will make him ruler over all his goods. But if that evil servant says in his heart, "My master is delaying his coming," and begins to beat his fellow servants, and to eat and drink with the drunkards, the master of that servant will come on a day when he is not looking for him and at an hour that he is not aware of, and will cut him in two and appoint him his portion with the hypocrites. There shall be weeping and gnashing of teeth.'
24.43-51
Peace but the sword
12.51-53
'Do not think that I came to bring peace on earth? I did not come to bring peace but a sword. For I have come to set a man against his father, a daughter against her mother, and a daughter-in-law against her mother-in-law; and a man's enemies will be those of his own household.'
10.34-36
Signs of the times
12.54-56
They asked him for a sign, and Jesus said: 'When it is evening you say, "It will be fair weather, for the sky is red", and in the morning, "It will be foul weather today, for the sky is red and threatening." Hypocrites! You know how to discern the face of the sky, but you cannot discern the signs of the times!'
16.2-3
Agree with adversary
12.57-59
'Agree with your adversary quickly, while you are on the way with him, lest your adversary deliver you to the judge, the judge hand you over to the officer, and you be thrown into prison. Assuredly, I say to you, you will by no means get out of there till you have paid the last penny.'
5.25-26
13.20-21
The kingdom of God
Jesus said: "The kingdom of heaven is like leaven, which a woman took and hid in three measures of meal till it was all leavened."
13.33
Narrow gate
13.24
Jesus said: 'Enter by the narrow gate; for wide is the gate and broad is the way that leads to destruction, and there are many who go in by it. Because narrow is the gate and difficult is the way which leads to life, and there are few who find it.'
7.13-14
Master of the house
13.25
Jesus said: 'When once the master of the house has risen up and shut the door, and you begin to stand outside and knock at the door, saying, "Lord, Lord, open to us," and he will answer and say to you, "Assuredly, I say to you, I do not know you."
25.10b-12
Lawlessness
13.26-27
'Many will say to me in that day, `Lord, lord, have we not prophesied in your name, cast out demons in your name, and done many wonders in your name?'
And then I will declare to them, 'I never knew you; depart from me, you who practice lawlessness!'
7.22-23

Poor Jerusalem
Jesus said: 'O Jerusalem, Jerusalem, the one who kills the prophets and stones those who are sent to her! How often I wanted to gather your children together, as a hen gathers her brood under her wings, but you were not willing! See! Your house is left to you desolate; and assuredly, I say to you, you shall not see me until the time comes when you say, "Blessed is he who comes in the name of the Lord!"'
23.37-39
14.16-23
Parable of the great banquet
Jesus said: 'The kingdom of heaven is like a certain king who arranged a marriage for his son, and sent out his servants to call those who were invited to the wedding; and they were not willing to come. Again, he sent out other servants, saying, "Tell those who are invited, '"See, I have prepared my dinner; my oxen and fatted cattle are killed, and all things are ready. Come to the wedding."'
But they made light of it and went their ways, one to his own farm, another to his business. And the rest seized his servants, treated them spitefully, and killed them. But when the king heard about it, he was furious. And he sent out his armies, destroyed those murderers, and burned up their city. Then he said to his servants, "The wedding is ready, but those who were invited were not worthy. Therefore go into the highways, and as many as you find, invite to the wedding."
So those servants went out into the highways and gathered together all whom they found, both bad and good. And the wedding hall was filled with guests.'
22.1-10
14.26-27
Carrying one's cross
Jesus said: 'He who loves father or mother more than me is not worthy of me. And he who loves son or daughter more than me is not worthy of me. And he who does not take his cross and follow after me is not worthy of me.'
10.37-38
15.4-7
Parable of the lost sheep
Jesus said: 'What do you think? If a man has a hundred sheep, and one of them goes astray, does he not leave the ninety-nine and go to the mountains to seek the one that is straying? And if he should find it, assuredly, I say to you, he rejoices more over that sheep than over the ninety-nine that did not go astray. Even so it is not the will of your Father who is in heaven that one of these little ones should perish.'
18.12-14
16.13
Not serving two masters
Jesus said: 'No one can serve two masters; for either he will hate the one and love the other, or else he will be loyal to the one and despise the other. You cannot serve God and mammon.'
6.24
16.16
The law in the kingdom of God

18.21-22
17.5-6
Jesus said to them: 'I say to you, if you have faith as a mustard seed, you will say to this mountain, "Move from here to there," and it will move; and nothing will be impossible for you.'
17.20
17.23-24
The coming of the Son of Man
Jesus said: 'Therefore if they say to you, "Look, the Son of Man is in the desert!" do not go out; or "Look, he is in the inner rooms!" do not believe it. For as the lightning comes from the east and flashes to the west, so also will the coming of the Son of Man be.'
24.26-27
17.26-27
'But as the days of Noah were, so also will the coming of the Son of Man be. For as in the days before the flood, they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark, and did not know until the flood came and took them all away, so also will the coming of the Son of Man be.'
24.37-39

24.40-41
Carcass
17.37
Jesus said: 'For wherever the carcass is, there the eagles will be gathered together.'
One possible explanation for this is that Marcion created an expansion of Mark to which he added many sayings and teachings. Then someone else expanded on that to produce proto-Luke. Both Matthew and canonical Luke are derived from proto-Luke, which is derived from Marcion's Gospel, which was derived from "Mark" (or proto-Mark).
