Paul said in Colossians 1:19-20 – “For God was pleased to have all his fullness dwell in him, and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross.”
The nails in Jesus’ time were handmade. And so, after a crucifixion, they removed them from the wood to “recycle” and use them again, perhaps in the next execution.
But did you know this? Crucifixion nails supposedly had magical powers to ward off evil, cure diseases and serve as good luck charms. And so before they could be recycled, some were stolen from the cadavers immediately after the execution and even robbed from tombs. (from F. T. Zugibe, The Crucifixion of Jesus: a forensic inquiry).
Imagine then, that there were people walking around with nails used as pendants, things that had pierced the flesh of a human being. And there were people who dared to enter tombs to remove them from corpses to use or sell. And all that to try to gain a little “magic power”!
Thank God, we don’t need magic, amulets, abracadabras, blessed oil, or holy water to feel safe in the world. According to Paul, we are reconciled to God, we are friends with him and he gives us full acceptance, through the cross of Christ. We don’t need anything magical or religious or even political or firearms or increased military to feel cozy – only, as Paul goes on to explain, “that we may stand firm in the faith, well grounded and steadfast, not abandoning the hope that the gospel offers.” (Col 1:23)
On another note: the Jehovah’s Witnesses teach that Christ was impaled on a stake, and that the traditional “cross” is a pagan symbol, introduced by the Catholic church in order to pollute the gospel. Although historically possible that he could have been killed on a stake, what Romans called a Crux Simplex, there is no evidence for it in Jesus’s case. Yes, the crosses were in different shapes – a capital T shape (Crux Commissa) or an X shape (Crux Decussata), the weight of literary and archaeological evidence indicates it was a cross in the traditional shape, not a stick or stake.
For example, an early hymn said “I extended my hands and hallowed my Lord, For the expansion of my hands is His sign, And my extension is the upright cross.” (Odes of Solomon 27). Another Christian of the 2nd century said Jesus was hung just like the Passover lamb was hung, that is, on two crossed spits of wood (Justin Martyr, Dialogue with Trypho 40). Athanasius said in his famous On the Incarnation of Christ ch. 25, that in his crucifixion, Jesus held wide his arms to embrace humanity: “For it is only on the cross that a man does with his hands spread out. Thus it was fitting for the Lord to bear this also and to spread out his hands, that with the one he might draw the ancient people and with the other those from the Gentiles and unite both in himself.”
I offer that, the Jehovah’s Witnesses’ insistence on the “stake” has less to do with history or any theological importance – after all, Jesus’ death, in whatever form, accomplishes the atonement! – but as in many sects, it is a device for “proving” that they are closer to the original, untainted faith.
The same historical data settle the question of whether they crucified them by nailing them or by tying them with rope to the beams. The evidence says that both were possible, and in the case of Yehohanan, who also was crucified in the first century, they nailed his feet but tied his arms with rope. In the case of Jesus, they used nails in his hands.
