The violence of "murderous hatred" is most manifest in reaction to Divine Mercy

It is precisely in the Passion, when the mercy of Christ is about to vanquish it, that sin most clearly manifests its violence and its many forms: unbelief, murderous hatred, shunning and mockery by the leaders and the people, Pilate's cowardice and the cruelty of the soldiers, Judas' betrayal - so bitter to Jesus, Peter's denial and the disciples' flight. However, at the very hour of darkness, the hour of the prince of this world, the sacrifice of Christ secretly becomes the source from which the forgiveness of our sins will pour forth inexhaustibly.

-- CCC 1851

The Church is the Mystical Body of Jesus Christ and the source of the mercy of God:

Thus a true filial spirit toward the Church can develop among Christians. It is the normal flowering of the baptismal grace which has begotten us in the womb of the Church and made us members of the Body of Christ. In her motherly care, the Church grants us the mercy of God which prevails over all our sins and is especially at work in the sacrament of reconciliation. With a mother's foresight, she also lavishes on us day after day in her liturgy the nourishment of the Word and Eucharist of the Lord.

-- CCC 2040

The Lord lives out His Passion in the Church and evil continues to show its face in the violence of murderous hatred so evident in these days.

"Jesus Christ, have mercy on us and on the whole world!"
