ABSOLUTELY ... NOT SO!!!The idea of Jesus dying on the cross is central to the Christian belief.
This is a prima-facie example of your missing the "truth"!
Hear me clearly!
It is in our Jesus' immaculate Birth ... Jesus The Christ's LIFE ... Christ's becoming sin ...giving up the ghost (the burning away of this sin) / the eternal CONQUERING of DEATH ... THROUGH ... HIS RESURRECTION !!! That remains "central to the Christian belief"!
TODAY ... "The Cross" is a thought -yielding symbolism of the a fore stated.
Therefore, it is not the death of our Messiah (for as stated "death" could not hold Him), rather it is The Rock ... Christ's - God's eternal LIFE on which "we" stand!
