Early Christian Beliefs About Luke the Evangelist
Early Christians often remembered Luke as Paul’s companion, the writer of a Gospel, and the author of Acts. Irenaeus, Caius, and Clement give the clearest early witness to that view. They also connect Luke with the title “beloved physician,” echoing Colossians 4:14. The evidence is strong for Luke’s role, but it is limited on other details about his life.

Origen, Commentary on John Background
...ding of the first fruits last, and may say that Acts and the letters of the Apostles came after the Gospels, and that this destroys our argument that the Gospel is the first fruits of all Scripture. To this we must reply that it is the conviction of those who are wise in Christ, who have profited from those epistles that are current, and who see them to be vouched for by the testimonies laid down in the Law and the Prophets, that the apostolic writings are wise and worthy of belief, and that they have great authority. But they are not on the same level as, "Thus says the Lord Almighty," 2 Corinthians 6:18. Consider Paul’s words on this point. When he declares that, "Every Scripture is inspired by God and profitable," 2 Timothy 3:16, does he include his own writings? Or does he not include such sayings as, "I say, and not the Lord," 1 Corinthians 7:12, and, "So I ordain in all the churches," 1 Corinthians 7:17, and, "What things I suffered at Antioch, at Iconium, at Lystra," 2 Timothy 3:11, and similar things which he writes by his own authority, and which do not quite have the character of words flowing from divine inspiration? Must we also show that the old Scripture is not Gos

Why did early Christians call Luke the beloved physician?
The sources explicitly call Luke the "beloved physician" and use medical language when speaking about him. The Bible passages tied to this title are Luke passages about physicians and healing, though those verses are background rather than direct biographical statements about Luke.

-
Irenaeus, Against Heresies: Book III Supporting witness
And again he says, in the Epistle to the Colossians: “Luke, the beloved physician, greets you.” But surely if Luke, who always preached in company with Paul, and is called by him “the beloved,” and with him performed the work of an evangelist, and was entrusted to hand down to us a Gospel, learned nothing different from him (Paul), as has been pointed out from his words, how can these men, who were never attached to Paul, boast that they have learned hidden and unspeakable mysteries?
Did early Christians treat Luke as an evangelist?
A few sources explicitly identify Luke as an evangelist and as a Gospel witness, though this theme is less developed than the claims about authorship and his connection to Paul. The Bible cards mainly support the evangelist theme indirectly through Luke’s own orderly account and ministry language.

Tertullian, Against Marcion Background
...o would be unwilling for us to trouble ourselves about food for our life, or clothing for our body, Luke 12:22-28, except Him who has already provided these things for man? Therefore, while He gives them to us, He forbids all anxiety about them, because such anxiety is an insult to His generosity. He has fitted life itself to be better than food. He has formed the substance of the body so that it is more than clothing. His ravens also neither sow nor reap, nor gather into storehouses, and yet they are fed by Him. His lilies and grass also do not toil or spin, and yet they are clothed by Him. Solomon too was supreme in glory, and yet he was not dressed like the lowly flower. Besides, nothing could be more abrupt than that one God should be giving His bounty, while the other tells us to take no thought about such a kind distribution, and does this in order to speak against His generosity. Whether indeed he means to belittle the Creator by not wanting such trifles to be thought about, things for which neither the crows nor the lilies labor, because they come of themselves to hand on account of their very worthlessness, will appear a little further on. Meanwhile, how is it that He r

Origen, Commentary on John Background
...atthew, we could hardly avoid examining these passages and recording the observations made on them. Luke, like Mark, remembers the passage, “The voice of one crying in the wilderness,” but he presents it in this way: Luke 3:2, “The word of God came to John, the son of Zacharias, in the wilderness. And he came into all the region around the Jordan preaching the baptism of repentance for the remission of sins; as it is written in the book of the words of Isaiah the prophet, The voice of one crying in the wilderness, Prepare the way of the Lord, make His paths straight.” Luke, however, adds the continuation of the prophecy: “Every valley shall be filled, and every mountain and hill shall be brought low, and the crooked shall become straight, and the rough ways smooth, and all flesh shall see the salvation of God.” He writes, like Mark, “Make His ways straight,” shortening, as we saw before, the text, “Make straight the ways of our God.” In the phrase, “And all the crooked shall become straight,” he leaves out the word “all,” and changes the word “straight” from plural to singular. Also, instead of the phrase, “The rough land into a plain,” he gives, “The rough ways into smooth ways

...y two parables, one at the close of the Gospel before us, Matthew 25:14-30, and one from the Gospel according to Luke, Luke 19:12-27. And not to prolong the discussion by quoting the exact words, since anyone who wishes can take it from Scripture himself, we will say that the parable according to Matthew declares, "For it is as when a man going into another country called his own servants, and delivered to them his own goods, and to one he gave five talents, and to another two, and to another one talent," Matthew 25:14-15. Then they took action with regard to what had been entrusted to them. And after a long time the lord of those servants comes, and it is written in these very words that he also makes a reckoning with them, Matthew 25:19. And compare the words, "And when he began to make a reckoning," Matthew 18:24, and consider that he called the going of the householder into another country the time at which we are at home in the body but absent from the Lord, 2 Corinthians 5:6. But his advent, when after a long time the lord of those servants comes, Matthew 25:19, is the time of the consummation in the judgment. For after a long time the lord of those servants comes and make

Luke 7:29 And all the people who heard, and the publicans, justified God, because they had been baptized with the baptism of John. Luke 7:30 But the Pharisees and the scribes wronged the purpose of God in themselves, because they were not baptized by him. Matthew 11:12a And from the days of John the Baptist until now, the kingdom of heaven is snatched away by violence. Luke 16:16 The law and the prophets were until John. After that, the kingdom of God is preached, and all press to enter it. Matthew 11:12b And those who exert themselves snatch it away. Matthew 11:13 All the prophets and the law until John prophesied. Matthew 11:14 And if you are willing, then receive it, that he is Elijah, who is to come. Matthew 11:15 Whoever has ears that hear, let him hear. Luke 16:17 It is easier for heaven and earth to perish than for one point of the law to pass away. Luke 7:31 To whom then shall I liken the people of this generation, and to whom are they like?

Irenaeus, Against Heresies: Book III Background
It is not possible for the Gospels to be more or fewer in number than they are. Since there are four zones of the world we live in and four principal winds, while the Church is spread throughout the whole world, and the "pillar and ground" of the Church is the Gospel and the spirit of life; it's fitting that it should have four pillars, breathing out immortality on every side and renewing humans. From this fact, it's clear that the Word, the Creator of all, He who sits upon the cherubim and contains all things, He who was revealed to humanity, has given us the Gospel in four aspects, but connected by one Spirit. As David says when pleading for His manifestation, “You that sit between the cherubim, shine forth.” For the cherubim were also four-faced, and their faces were images of the arrangement of the Son of God. As Scripture says, “The first living creature was like a lion,” symbolizing His powerful work, His leadership, and royal power; the second living creature was like a calf, signifying His sacrificial and priestly order; the third had, as it were, the face of a man—clearly describing His coming as a human; the fourth was like a flying eagle, pointing out the gift of the Spi

...f them were advanced in age. While he was serving as priest before God in the order of his service, according to the custom of the priesthood, it was his turn to burn incense. So he entered the temple of the Lord. And the whole gathering of the people was praying outside at the time of the incense. Then the angel of the Lord appeared to Zacharias, standing at the right side of the altar of incense. When Zacharias saw him, he was troubled, and fear fell upon him. But the angel said to him, "Do not be troubled, Zacharias, because your prayer has been heard, and your wife Elizabeth will bear you a son, and you shall call his name John. You will have joy and gladness, and many will rejoice at his birth. For he will be great before the Lord. He will not drink wine or strong drink, and he will be filled with the Holy Spirit while he is in his mother's womb. He will turn back many of the children of Israel to the Lord their God. And he will go before Him in the spirit and power of Elijah the prophet, to turn back the heart of the fathers to the sons, and those who do not obey to the knowledge of the righteous, and to prepare for the Lord a perfect people." And Zacharias said to the ang

Tatian, The Diatessaron Background
He spoke a parable because he was nearing Jerusalem, and they supposed that at that time the kingdom of God was about to appear. He said to them, “A man, a son of a great family, went into a far country to receive a kingdom and return. He called his ten servants, gave them ten shares, and said to them, ‘Trade until the time of my coming.’ But the people of his city hated him and sent messengers after him, saying, ‘We do not want this man to reign over us.’ “When he had received a kingdom and returned, he ordered the servants to whom he had given the money to be called to him, so that he might know what each of them had gained by trading. The first came and said, ‘My lord, your share has gained ten shares.’ The king said to him, ‘You good and faithful servant, since you have been found faithful in a little, be set over ten districts.’ The second came and said, ‘My lord, your portion has gained five portions.’ He said to him also, ‘And you shall be set over five districts.’ “Another came and said, ‘My lord, here is your portion, which I kept laid away in a napkin. I feared you, because you are a hard man. You take what you did not leave, and seek what you did not give, and reap what
