Darkness at the crucifixion: metaphor or real history?
Quoting from link ~~~~"Phlegon was a Greek historian who wrote an extensive chronology aroundAD137: "In the fourth year of the 202nd Olympiad (i.e.,AD33) there was ‘the greatest eclipse of the sun’ and that ‘it became night in the sixth hour of the day [i.e., noon] so that stars even appeared in the heavens. There was a great earthquake in Bithynia, and many things were overturned in Nicaea.’7
Phlegon provides powerful confirmation of the Gospel accounts. He identifies the year and the exact time of day. In addition, he writes of an earthquake accompanying the darkness, which is specifically recorded in Matthew’s Gospel (
Matthew 27:51). However, like Thallus, he fallaciously attempts to interpret the darkness as a direct effect of a solar eclipse.
Africanus composed a five volume
History of the World aroundAD221. He was also a pagan convert to Christianity. His historical scholarship so impressed Roman Emperor Alexander Severus that Africanus was entrusted with the official responsibility of building the Emperor’s library at the Pantheon in Rome. Africanus writes:
"On the whole world there pressed a most fearful darkness; and the rocks were rent by an earthquake, and many places in Judea and other districts were thrown down. This darkness Thallus, in the third book of his
History, calls, as appears to me without reason, an eclipse of the sun. For the Hebrews celebrate the passover on the 14th day according to the moon, and the passion of our Savior falls on the day before the passover; but an eclipse of the sun takes place only when the moon comes under the sun. And it cannot happen at any other time but in the interval between the first day of the new moon and the last of the old, that is, at their junction: how then should an eclipse be supposed to happen when the moon is almost diametrically opposite the sun? Let opinion pass however; let it carry the majority with it; and let this portent of the world be deemed an eclipse of the sun, like others a portent only to the eye. Phlegon records that, in the time of Tiberius Caesar, at full moon, there was a full eclipse of the sun from the sixth hour to the ninth—manifestly that one of which we speak. But what has an eclipse in common with an earthquake, the rending rocks, and the resurrection of the dead, and so great a perturbation throughout the universe? Surely no such event as this is recorded for a long period.8 "
Africanus rightly argues that a solar eclipse could not have occurred during the lunar cycle of the Passover, as
this diagram shows. He also questions the link between an eclipse, an earthquake, and the miraculous events recorded in Matthew’s Gospel. Eclipses do not set off earthquakes and bodily resurrections. We also know that eclipses only last for several minutes, not three hours. For Africanus, naturalistic explanations for the darkness at the crucifixion were grossly insufficient, as he showed by applying real science. ~~~~~End of quote from link
Looks to me that when our Creator took our sins upon Himself on the cross in experiencing that separation from the Father, it was also seen in His creation by that unexplained darkness.
Jesus suffered much as God Our Redeemer out of love for us in giving Himself as a ransom for many.
John 15:13 Greater love hath no man than this, that a man lay down his life for his friends.
May we see the love of God for us in that He is willing to take us all the way Home as the Good Shepherd He is in helping us to abide in His words in following Him as His disciples in loving others as ourselves by the same grace of God we are saved by... by faith in Jesus Christ.
Romans 8:31 What shall we then say to these things? If God be for us, who can be against us? 32 He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things?
33 Who shall lay any thing to the charge of God's elect? It is God that justifieth. 34 Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us.
35 Who shall separate us from the love of Christ? shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword? 36 As it is written, For thy sake we are killed all the day long; we are accounted as sheep for the slaughter. 37 Nay, in all these things we are more than conquerors through him that loved us. 38 For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, 39 Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.
