First off, Catholic teaching has always maintained that Jesus did not have to die on the cross to redeem us. Indeed, God is God, He is perfect: Jesus having a pin prick is just as efficacious in redeeming us as Him suffering on the Cross. Heck, God is Omnipotent: He could have just willed it, thought about it, and our sins could have been wiped away.
Read Fr. Serpa’s answer to this question.
Also, read St. Pope John Paul II’s answer to the same question.
The short answer from the two Catholic sources is that Jesus died so He can show His unfathomable love for us, among other things by (1) being one with us in our suffering, and (2) letting us participate in His salvation of men.
But for many, which to be honest included me, this explanation is lacking. An act of love is useless if the act repulses the loved one; indeed, it is less than useless, because it shows that either the lover does not know the beloved, or does not care of the beloved’s wants. As an example, imagine a man mutilating his own body just to prove his love for a woman. Unless the woman is as insane as the man, such an act would only disgust the woman and would most certainly not be a loving act but a monstrous one! And to be honest, Jesus’ act of dying for us on the Cross can really seem like that: not a loving act, but a monstrous one.
I had thought about this before, and the only answer I could think of was that if Jesus’ death on the Cross is a loving act for us, then that means God knew that
we, deep in our hearts, want the consequence of Jesus’ death.
And what is this consequence?
Glory.
We were made to
be the Glory of God (1 Corinthians 11:7), and if that is so, that is one of our deepest desires. And glory is not achieved in comfort, but in struggle.
“The world offers you comfort. But you were not made for comfort. You were made for greatness.” ---- Pope Emeritus Benedict XVI
Indeed, man knew this from the beginning. We have always admired and revered great men and women since ancient times. We love sports and challenges. Glory even rears its ugly head with wars and crime. Indeed, we have parables of men rejecting ideal worlds because they have no struggle in them; the movies
The Matrix and
Star Trek Generations come into mind.
And all of this would not be possible if God just willed sin away. We would have not been able to struggle and be glorious, and thus we would have not been able to fulfill our purpose.
As the Church sings every Easter:
Exult, let them exult, the hosts of heaven,
exult, let Angel ministers of God exult,
let the trumpet of salvation
sound aloud our mighty King’s triumph!
Be glad, let earth be glad,
as glory floods her,
ablaze with light from her eternal King,
let all corners of the earth be glad,
knowing an end to gloom and darkness.
Rejoice, let Mother Church also rejoice,
arrayed with the lightning of his glory,
let this holy building shake with joy,
filled with the mighty voices of the peoples.
…
O wonder of your humble care for us!
O love, O charity beyond all telling,
to ransom a slave you gave away your Son!
O truly necessary sin of Adam,
destroyed completely by the Death of Christ!
O happy fault
that earned so great, so glorious a Redeemer!
