Luke omits in his version of the Olivet Discourse from Mark and Matthew the coming of false Christs who do signs and wonders

 For there shall arise false Christs, and false prophets, and shall shew great signs [σημεῖα] and wonders [τέρατα]; insomuch that, if it were possible, they shall deceive the very elect. 

-- Matthew 24:24

For false Christs and false prophets shall rise, and shall shew signs and wonders, to seduce, if it were possible, even the elect.  

-- Mark 13:22

As detailed below, Luke positively values the signs and wonders of the apostolic age. He certainly doesn't want a Jesus who throws shade on them, especially since it is really "the holy child Jesus" by whose name the signs and wonders are done.

And I will shew wonders in heaven above, and signs in the earth beneath; blood, and fire, and vapour of smoke:  

-- Acts 2:19

Ye men of Israel, hear these words; Jesus of Nazareth, a man approved of God among you by miracles [δυνάμεσιν] and wonders and signs, which God did by him in the midst of you, as ye yourselves also know: 

-- Acts 2:22

And fear came upon every soul: and many wonders and signs were done by the apostles.  

-- Acts 2:43

And now, Lord, behold their threatenings: and grant unto thy servants, that with all boldness they may speak thy word, By stretching forth thine hand to heal; and that signs and wonders may be done by the name of thy holy child Jesus.

-- Acts 4:29f.

And by the hands of the apostles were many signs and wonders wrought among the people; (and they were all with one accord in Solomon's porch.  

-- Acts 5:12

And Stephen, full of faith and power, did great wonders and miracles [signs] among the people. 

-- Acts 6:8

He brought them out, after that he had shewed wonders and signs in the land of Egypt, and in the Red sea, and in the wilderness forty years.  

-- Acts 7:36

Long time therefore abode they speaking boldly in the Lord, which gave testimony unto the word of his grace, and granted signs and wonders to be done by their hands. 

-- Acts 14:3

Then all the multitude kept silence, and gave audience to Barnabas and Paul, declaring what miracles [signs] and wonders God had wrought among the Gentiles by them.  

-- Acts 15:12

Luke's freedom in eliding entirely the "false Christs" line at a minimum shows that the apocalyptic tradition narrated in Matthew 24, Mark 13, and Luke 21 is not yet fixed in the evangelists' own time as they struggled to reimagine and repurpose the (failed) apocalyptic material of the earlier time of the historical Jesus which lies behind it.

It has long been recognized that this apocalyptic material is a series of independent units more or less successfully woven together into a "composite discourse", but it is a "tangled skein", some elements of which might be editorial by the evangelists, some pre-existing apocalyptic either Jewish or Jewish Christian, some authentically dominical, et cetera. So Vincent Taylor, The Gospel According to St. Mark, London 2nd edition, 1966, 1977, pp. 498ff., who considers Matthew a later version of Mark, but Luke, who has "little linguistic agreement with Mk.", to be a stand alone witness presenting material from "independent" sources who must be reckoned with for the development of apocalyptic but often is not.

As Taylor recognizes, Mark's vocabulary in 13:21f. has the "later ring" of "primitive Christianity" about it. It is an apocalyptic outlook now "strange to the mind of Jesus". So it would not be odd then for Luke to exclude it, concerned as he self-consciously is to lay out his history more accurately than have other evangelists.

What we have in these apocalyptic narratives, including Luke's, is revisionism at work.

The "false Christs" idea reflects later developments, a later Christianity on the way from a Judaism which had its own false prophets, to a later Pauline world populated also by a false gospel (II Cor. 11:4; Gal. 1:6), false apostles (II Cor. 11:13), false angels (II Cor. 11:14), the son of perdition (II Thes. 2:3), and ultimately the Antichrist(s) of I and II John.

The historical Jesus, imagining the imminent end of the world in his own lifetime, would never have imagined such developments by definition.

But Luke himself hasn't thought of such things, of course, nor about the implications for either his Gospel or his Apostle (Acts, primarily about Paul). Luke's aim is to present the signs and wonders characteristic of the early and middle Pauline period as proof of his Gospel.

What is also often not considered enough is that the false Christs language of Matthew 24 and Mark 13 might actually be explicit anti-Pauline propaganda, in which case this calumny might represent the particular trigger, among other deficiencies, which motivated Luke to compose his definitive two-volume work in defense of the real Jesus and his hero Paul as he understands them, in order that his patron Theophilus "may know the certainty of those things" in which he was instructed (Luke 1:4).

Paul claimed his gospel was not mediated by flesh and blood, but he must have heard something at Stephen's stoning

But I certify you, brethren, that the gospel which was preached of me is not after man. For I neither received it of man, neither was I taught it, but by the revelation of Jesus Christ. ... But when it pleased God, who separated me from my mother's womb, and called me by his grace, To reveal his Son in me, that I might preach him among the heathen; immediately I conferred not with flesh and blood: Neither went I up to Jerusalem to them which were apostles before me; but I went into Arabia, and returned again unto Damascus. Then after three years I went up to Jerusalem to see Peter, and abode with him fifteen days. But other of the apostles saw I none, save James the Lord's brother.

-- Galatians 1:11f., 15ff.

Before this conversion, Luke puts Paul in Jerusalem keeping the coats of those who stoned Stephen for his long proclamation of the gospel and corresponding indictment of Israel:

Then they cried out with a loud voice, and stopped their ears, and ran upon him with one accord, And cast him out of the city, and stoned him: and the witnesses laid down their clothes at a young man's feet, whose name was Saul. And they stoned Stephen, calling upon God, and saying, Lord Jesus, receive my spirit. And he kneeled down, and cried with a loud voice, Lord, lay not this sin to their charge. And when he had said this, he fell asleep. And Saul was consenting unto his death.

 

-- Acts 7:57ff.

How do you consent to something the details of which you are not aware?

The popular understanding about Jesus was that he was a prophet, and perhaps the coming prophet like unto Moses

Moses Aaron and Hur by John Everett Millais

-- Mark 8:27f.

And there came a fear on all: and they glorified God, saying, That a great prophet is risen up among us; and, That God hath visited his people. ... Now when the Pharisee which had bidden him saw it, he spake within himself, saying, This man, if he were a prophet, would have known who and what manner of woman this is that toucheth him: for she is a sinner.

-- Luke 7:16, 39

Now Herod the tetrarch heard of all that was done by him: and he was perplexed, because that it was said of some, that John was risen from the dead; And of some, that Elias had appeared; and of others, that one of the old prophets was risen again. ... And it came to pass, as he was alone praying, his disciples were with him: and he asked them, saying, Whom say the people that I am? They answering said, John the Baptist; but some say, Elias; and others say, that one of the old prophets is risen again.

-- Luke 9:7f., 18f.

Nevertheless I must walk to day, and to morrow, and the day following: for it cannot be that a prophet perish out of Jerusalem.

-- Luke 13:33

And he said unto them, What things? And they said unto him, Concerning Jesus of Nazareth, which was a prophet mighty in deed and word before God and all the people:

-- Luke 24:18f.

And this is the record of John, when the Jews sent priests and Levites from Jerusalem to ask him, Who art thou? And he confessed, and denied not; but confessed, I am not the Christ. And they asked him, What then? Art thou Elias? And he saith, I am not. Art thou that prophet? And he answered, No. ... And they asked him, and said unto him, Why baptizest thou then, if thou be not that Christ, nor Elias, neither that prophet?

-- John 1:19ff, 25.

The woman saith unto him, Sir, I perceive that thou art a prophet.

-- John 4:19

-- John 6:14f.

Many of the people therefore, when they heard this saying, said, Of a truth this is the Prophet. ... They [the Pharisees] answered and said unto him [Nicodemus], Art thou also of Galilee? Search, and look: for out of Galilee ariseth no prophet.

-- John 7:40, 52

They say unto the blind man again, What sayest thou of him, that he hath opened thine eyes? He said, He is a prophet.

-- John 9:17

For Moses truly said unto the fathers, A prophet shall the Lord your God raise up unto you of your brethren, like unto me; him shall ye hear in all things whatsoever he shall say unto you.

-- Deuteronomy 18:15, 17f.

And Joshua the son of Nun was full of the spirit of wisdom; for Moses had laid his hands upon him: and the children of Israel hearkened unto him, and did as the LORD commanded Moses. And there arose not a prophet since in Israel like unto Moses, whom the LORD knew face to face,

-- Deuteronomy 34:9f.

Paul The Stoner: Do Not Associate With Sexual Sinners In Your Midst

Saul watched their coats (Acts 7:58)

 

 

 

It isn't my responsibility to judge outsiders, but it certainly is your responsibility to judge those inside the church who are sinning. God will judge those on the outside; but as the Scriptures say, "You must remove the evil person from among you."

-- 1 Corinthians 5:12f.

This is what Paul is quoting:

[I]f it is true and certain that such an abominable thing has been done in Israel, then you shall bring forth to your gates that man or woman who has done this evil thing, and you shall stone that man or woman to death with stones. On the evidence of two witnesses or of three witnesses he that is to die shall be put to death; a person shall not be put to death on the evidence of one witness. The hand of the witnesses shall be first against him to put him to death, and afterward the hand of all the people. So you shall purge the evil from the midst of you.

-- Deuteronomy 17:4ff.

Evidently Paul was unmoved by this, if he knew it at all:

"Teacher, this woman has been caught in the act of adultery. Now in the law Moses commanded us to stone such. What do you say about her?" This they said to test him, that they might have some charge to bring against him. Jesus bent down and wrote with his finger on the ground. And as they continued to ask him, he stood up and said to them, "Let him who is without sin among you be the first to throw a stone at her."

-- John 8:4ff.
