I believe in God the Father, Almighty, Maker of heaven and earth And in Jesus Christ, his only begotten Son, our Lord Who was conceived by the Holy Ghost, born of the Virgin Mary Suffered under Pontius Pilate; was crucified, dead and buried; He descended into hell The third day he rose again from the dead He ascended into heaven, and sits at the right hand of God the Father Almighty From thence he shall come to judge the quick and the dead I believe in the Holy Ghost I believe a holy catholic church; the communion of saints The forgiveness of sins The resurrection of the body And the life everlasting. Amen. 
The facts of Christ’s crucifixion are essential to Christian belief. “Now I would remind you, brothers, of the gospel I preached to you, which you received, in which you stand, and by which you are being saved, if you hold fast to the word I preached to you—unless you believed in vain. For I delivered to you as of first importance what I also received: that Christ died for our sins in accordance with the Scriptures, that he was buried…” (1 Corinthians 15:1–4, ESV) I am not aware of any dispute regarding Jesus’ crucifixion. Even those who deny that Jesus was God, who claim that he was historically only a man, and maybe a Rabbi, generally will accept that he was crucified.
Most scholars in the third quest for the historical Jesus consider the crucifixion indisputable, as do Bart Ehrman, John Dominic Crossan and James Dunn. Although scholars agree on the historicity of the crucifixion, they differ on the reason and context for it, e.g. both E. P. Sanders and Paula Fredriksen support the historicity of the crucifixion, but contend that Jesus did not foretell his own crucifixion, and that his prediction of the crucifixion is a Christian story. Géza Vermes also views the crucifixion as a historical event but believes this was due to Jesus’ challenging of Roman authority. On the other hand, Maurice Casey and John P. Meier state that Jesus did predict his death, and this actually strengthened his followers’ belief in his Resurrection.https://www.wikiwand.com/en/Historical_Jesus
As the above quote would indicate, the dispute about the crucifixion surrounds the historical context and, more importantly, the supernatural aspect of Jesus predicting it. Yet Paul states clearly that the death of Christ was “according to the Scriptures.” The Biblical test is the only one that really matters, unless we want to deny the inspiration of Scripture. (That is one of the amazing supernatural aspects to the Word of God. All Scripture is in harmony and few things are stated that are not repeated throughout.)
Peter is one who clearly states that Christ Jesus predicted his death and that the prophets knew of it by the Holy Spirit. “Concerning this salvation, the prophets who prophesied about the grace that was to be yours searched and inquired carefully, inquiring what person or time the Spirit of Christ in them was indicating when he predicted the sufferings of Christ and the subsequent glories. It was revealed to them that they were serving not themselves but you, in the things that have now been announced to you through those who preached the good news to you by the Holy Spirit sent from heaven, things into which angels long to look.” (1 Peter 1:10–12, ESV)
Most would agree that the predictions of the death (and resurrection) of Christ throughout the Old Testament are plentiful. Isaiah 53 is a good example.
“He was despised and rejected by men, a man of sorrows and acquainted with grief; and as one from whom men hide their faces he was despised, and we esteemed him not. Surely he has borne our griefs and carried our sorrows; yet we esteemed him stricken, smitten by God, and afflicted. But he was pierced for our transgressions; he was crushed for our iniquities; upon him was the chastisement that brought us peace, and with his wounds we are healed. All we like sheep have gone astray; we have turned—every one—to his own way; and the Lord has laid on him the iniquity of us all.”Isaiah 53:3–6, ESV
The death of the Savior was predicted even within the curse from the original fall of Adam and Eve.
“The Lord God said to the serpent, “Because you have done this, cursed are you above all livestock and above all beasts of the field; on your belly you shall go, and dust you shall eat all the days of your life. I will put enmity between you and the woman, and between your offspring and her offspring; he shall bruise your head, and you shall bruise his heel.”Genesis 3:14–15, ESV
If you rule out the opinions of those who “search for the Historical Jesus,” I am unaware of any Biblical scholar who denies that Jesus was innocent yet crucified, that his crucifixion was the payment required by God’s justice for the forgiveness of sins, and that this is a real act in history with eternal and historical significance.
“But now the righteousness of God has been manifested apart from the law, although the Law and the Prophets bear witness to it— the righteousness of God through faith in Jesus Christ for all who believe. For there is no distinction: for all have sinned and fall short of the glory of God, and are justified by his grace as a gift, through the redemption that is in Christ Jesus, whom God put forward as a propitiation  by his blood, to be received by faith.”Romans 3:21–25, ESV
Why does the creed include he was dead and buried to crucified? I can suggest two reasons. First, over time, there have developed theories that Jesus did not die, but merely fainted or lost consciousness. Such theories are explanations for the resurrection which being a supernatural event cannot be historical as well.
Thus grew and thus died the theory of the rupture of the heart of Jesus. It is only an evidence that there is no proof inThe ‘Rupture of the Heart’ Theory of the Death of Jesus, The Review of Religions, May 1905, p. 191.
the hands of the Christians that Jesus died on the cross, and like the drowning man they catch at every straw. But the proof is now complete that Jesus did not die upon the cross, and the tomb at Khan Yar is a living witness of this fact, the truth of which would soon be seen by the world.
If you are interested, there are more recent articles that are similar here, here, and here. All of these articles come from the same source. However, they are representative of the overall theory that Jesus did not die on the cross. Yet, each one uses science as a credible proof of their point and they are still speculative at best. The creed takes into account the nature of human sin and it does not allow for theory. Jesus died according to all four gospels and all remaining New Testament writings.
Second, the strongest evidence for the death of Jesus is that he was buried. Mark wrote about the event this way, “And when evening had come, since it was the day of Preparation, that is, the day before the Sabbath, Joseph of Arimathea, a respected member of the council, who was also himself looking for the kingdom of God, took courage and went to Pilate and asked for the body of Jesus. Pilate was surprised to hear that he should have already died. And summoning the centurion, he asked him whether he was already dead. And when he learned from the centurion that he was dead, he granted the corpse to Joseph. And Joseph bought a linen shroud, and taking him down, wrapped him in the linen shroud and laid him in a tomb that had been cut out of the rock. And he rolled a stone against the entrance of the tomb. Mary Magdalene and Mary the mother of Joses saw where he was laid.” (Mark 15:42–47, ESV)
Even before people thought to argue that Jesus did not die, Mark answers their objection. “Pilate was surprised to hear that he should have already died.” Those who were crucified with Jesus had their legs broken to hasten the process. As long as someone on the cross still lived, the Roman guards had to stay so that no one could come and save them. Instead of breaking Jesus legs, they thrust a spear in his side. This too was to speed up his death. Speculation that following all of the physical suffering Jesus experienced before the cross did not significantly effect his death, and that the spear thrust itself did not hasten it is foolishness. If he did not die, then there is no Christianity, and I can’t help but wonder if this is the motivation for the argument.
We must note that the creed is not interested in speculation. It is doctrine, the teaching of the Christian Church from the beginning. It is a concise statement telling us what we must believe to be accounted members of the Way. It is truth physiologically and historically with enough evidence to verify it. Paul makes sure that we know there were many witnesses to the resurrected Jesus, and we are told that the disciple Thomas had his doubts answered by touching his wounds. The problem is not evidence, though. It is interpretation, and interpretation of something always begins with what the interpreter brings of his or her self.
The beginning of any belief system is one’s world view. Modern science is rooted in materialism. Modern education is a matter of indoctrination. All of the ideas of mankind begin either with God or no god. One is truth and the other is not. There are no options in-between, no compromises to be made. I believe…
