The term "Son of God" (or variations like "God's Son") appears frequently in the four Gospels (Matthew, Mark, Luke, and John). Here's a breakdown of where you can find it:
Matthew:
* 3:17: (At Jesus's baptism) "And a voice from heaven said, 'This is my beloved Son, with whom I am well pleased.'"
* 4:3, 4:6: (Temptation in the wilderness) "If you are the Son of God..." (Satan's challenge)
* 8:29: (Demons) "What have you to do with us, O Son of God? Have you come here to torment us before the time?"
* 14:33: (After Jesus walks on water) "And those in the boat worshiped him, saying, 'Truly you are the Son of God.'"
* 16:16: (Peter's confession) "Simon Peter replied, 'You are the Christ, the Son of the living God.'"
* 26:63: (Jesus's trial before the Sanhedrin) "The high priest said to him, 'I adjure you by the living God, tell us if you are the Christ, the Son of God.'"
* 27:40: (Mocking at the cross) "If you are the Son of God, come down from the cross."
* 27:43: (Mocking at the cross) "He trusts in God; let God deliver him now, if he desires him. For he said, 'I am the Son of God.'"
* 27:54: (Centurion after the earthquake) "When the centurion and those who were with him, keeping watch over Jesus, saw the earthquake and what took place, they were filled with awe and said, 'Truly this was the Son of God!'"
Mark:
* 1:1: "The beginning of the gospel of Jesus Christ, the Son of God." (Some manuscripts omit "Son of God" here)
* 1:11: (At Jesus's baptism) "And a voice came from heaven, 'You are my beloved Son; with you I am well pleased.'"
* 3:11: (Demons) "And whenever the unclean spirits saw him, they fell down before him and cried out, 'You are the Son of God.'"
* 5:7: (Demons) "And crying out with a loud voice, he said, 'What have you to do with me, Jesus, Son of the Most High God? I adjure you by God, do not torment me.'"
* 15:39: (Centurion at the cross) "And when the centurion, who stood facing him, saw that in this way he breathed his last, he said, 'Truly this man was the Son of God!'"
Luke:
* 1:35: (Angel Gabriel to Mary) "And the angel answered her, 'The Holy Spirit will come upon you, and the power of the Most High will overshadow you; therefore the child to be born will be called holy—the Son of God.'"
* 3:22: (At Jesus's baptism) "and the Holy Spirit descended on him in bodily form, like a dove; and a voice came from heaven, 'You are my beloved Son; with you I am well pleased.'"
* 4:3, 4:9: (Temptation in the wilderness) "If you are the Son of God..." (Satan's challenge)
* 4:41: (Demons) "And demons also came out of many, crying, 'You are the Son of God!' But he rebuked them and would not allow them to speak, because they knew that he was the Christ."
* 9:35: (Transfiguration) "And a voice came out of the cloud, saying, 'This is my Son, my Chosen One; listen to him!'"
* 10:22: "All things have been handed over to me by my Father, and no one knows who the Son is except the Father, or who the Father is except the Son and anyone to whom the Son chooses to reveal him."
* 22:70: (Jesus's trial) "And they all said, 'Are you the Son of God, then?' And he said to them, 'You say that I am.'"
John:
John's Gospel emphasizes Jesus's divine nature more explicitly. The phrase "Son of God" and similar terms are very important and appear frequently:
* 1:14: "And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth." (Implies Son of God, although not explicitly stated)
* 1:18: "No one has ever seen God; the only God, who is at the Father's side, he has made him known." (Most translations have "only God" or "only begotten God." Some have "only begotten Son.")
* 1:34: "And I have seen and have borne witness that this is the Son of God." (John the Baptist)
* 3:16: "For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life."
* 3:18: "Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God."
* 5:25: "Truly, truly, I say to you, an hour is coming, and is now here, when the dead will hear the voice of the Son of God, and those who hear will live."
* 5:19-23: (Jesus speaking about his relationship with the Father). While not using the exact phrase "Son of God" repeatedly here, this section is dedicated to explaining the Father-Son relationship and Jesus' authority as the Son.
* 9:35: (Jesus to the healed blind man) "Do you believe in the Son of Man?"
* 10:36: (Jesus) "do you say of him whom the Father consecrated and sent into the world, ‘You are blaspheming,’ because I said, ‘I am the Son of God’?"
* 11:4: (Jesus) "This illness does not lead to death. It is for the glory of God, so that the Son of God may be glorified through it."
* 11:27: (Martha to Jesus) "She said to him, 'Yes, Lord; I believe that you are the Christ, the Son of God, who is coming into the world.'"
* 19:7: (Jews to Pilate) "The Jews answered him, 'We have a law, and according to that law he ought to die because he has made himself the Son of God.'"
* 20:31: "but these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name."
Key Observations:
* Divine Voice: At Jesus's baptism (and the Transfiguration), God the Father identifies Jesus as "my beloved Son."
* Demonic Recognition: Demons frequently recognize Jesus as the "Son of God," often against their will.
* Human Confession: Peter's confession ("You are the Christ, the Son of the living God") is a pivotal moment. The Centurion's declaration at the crucifixion is also significant.
* Jesus's Claims: Jesus himself sometimes refers to himself as the Son of God, though he often uses other titles like "Son of Man." In John's Gospel, especially, Jesus directly claims a unique and intimate relationship with God, implying his divine sonship.
* John's Emphasis: The Gospel of John is the most explicit in presenting Jesus as the divine Son of God, equal to the Father. John's stated purpose in writing is to convince readers that Jesus *is* the Son of God.
* Variations: While "Son of God" is the most common phrasing, you'll also see "God's Son," "the Son," "my Son," "the only Son," and other related phrases that carry the same theological weight.
