the mystery of the crucifixion
Christ’s 2 commandments were to love God and love your neighbor.
In His crucifixion, Jesus fulfilled those 2 commandments and set an example for us all. He accepted a painful, ignominious death on the cross out of obedience (love) of the Father and out of love for fallen, suffering humanity.
The sorrowful mysteries (Jesus’ passion, crucifixion, and death) had to happen before the glorious mysteries could occur.
