I completely disagree; you seem to want to water everything down and dismissing it as insignificant. Without the Crucifixion and the shedding of divine blood, there is no Salvation.
At the Last Supper, just before his crucifixion, Jesus said:
26 While they were eating, Jesus took bread, and when he had given thanks, he broke it and gave it to his disciples, saying, “Take and eat; this is my body.”
27 Then he took a cup, and when he had given thanks, he gave it to them, saying, “Drink from it, all of you. 28 This is my blood of the new covenant, which is poured out for many for the forgiveness of sins." 29
The cross is both a symbol of the Crucifixion and of man's suffering. But everyone associates it primarily with the Crucifixion of Jesus, and with the shedding of divine blood as a means of redemption of sin.
I was raised a Catholic, and was an altar boy for many years. We celebrated the symbolic partaking of divine flesh and blood each time in the Mass. This is known as transubstantiation.
