In prayer, one comes to know one’s self, one’s creatureliness and misery, and at the same time God’s immense love. If one turns the eyes of the spirit to the Heart of Christ, the soul contemplates the Word incarnate, divinity united to humanity. In this Heart of mercy, one comes to the knowledge of God and his infinite love for humanity. The cell of self-knowledge is found within the heart: the human heart and the Heart of God as revealed in Jesus Christ.

“Blessed are the merciful, for they shall obtain mercy. — Matthew 5:7

The Old Testament repeatedly describes God as merciful, and Israel is called to imitate God’s mercy. Mercy involves an inward identification with those in need and an outward action of kindness and generosity toward them. In this beatitude Jesus emphasizes the reciprocal nature of mercy—a theme Matthew develops throughout his Gospel. God will show his mercy to us to the extent that we are merciful to others.

My notes: Italics and bold added by me.  The mercy we receive is the mercy we give and the reverse, the mercy we give is the mercy we receive.

Go and learn what this means, ‘I desire mercy, and not sacrifice.’ For I came not to call the righteous, but sinners.”  (Matthew 9:13)

For I desire mercy and not sacrifice,
the knowledge of God, rather than burnt offerings. (Hosea 6:6)

“This passage originally denounced Israelites who were trying to cover up their grave sins with external acts of piety such as sacrifice. Since sacrifice was supposed to express covenant love and faithfulness, Hosea said that God desires “mercy,” not (empty) sacrifices. The Greek word for mercy here is eleos, which in the Septuagint often represents the Hebrew word hesed, meaning loyal, steadfast covenant love. Jesus uses this quotation from Hosea to challenge the Pharisees not to allow external practices such as their table fellowship regulations to replace the steadfast love that must be shown to God and all his people, including sinners and tax collectors who have fallen away (23:23). Embodying Israel’s mission to be light to the whole world (5:14), Jesus did not come to call the righteous but sinners.”

My Notes: Divine Mercy Sunday 2016. God is our Father, and mercy is not just the forgiveness of our sins, but “loyal, steadfast covenant love”. So loyal and steadfast need to describe how we love both God and our family, friends and neighbors.

You are my God; have mercy on me, O Lord,
for to you do I cry all the day. (Psalm 86:2-3)

1. No greater gift could God have given to men than in making His Word, by which He created all things, their Head, and joining them to Him as His members: that the Son of God might become also the Son of man, one God with the Father, one Man with men; so that when we speak to God in prayer for mercy, we do not separate the Son from Him; and when the Body of the Son prays, it separates not its Head from itself: and it is one Saviour of His Body, our Lord Jesus Christ, the Son of God, who both prays for us, and prays in us, and is prayed to by us.

My Notes: Our prayer to the Father for mercy is the one same prayer of Jesus to the Father for the same mercy. Jesus prays with us, we have the same prayer: mercy.

… as we forgive those who trespass against us

Now—and this is daunting—this outpouring of mercy cannot penetrate our hearts as long as we have not forgiven those who have trespassed against us. Love, like the Body of Christ, is indivisible; we cannot love the God we cannot see if we do not love the brother or sister we do see (See 1 John 4:20). In refusing to forgive our brothers and sisters, our hearts are closed and their hardness makes them impervious to the Father’s merciful love; but in confessing our sins, our hearts are opened to his grace.

My Notes:
Our prayer to receive mercy from Our Father in Heaven is bound together with our prayer in which we give mercy to our brothers and sisters here on earth.

“Jesus, I trust in you!”. This is the simple prayer that Sr Faustina taught us, and which we can have on our lips at every moment of our lives. How often, as a worker, a student and then as a priest and bishop, in the difficult periods of the history of Poland, I also repeated this simple and profound aspiration and experience its efficacy and power.

Mercy is one of the most wonderful attributes of the Creator and of the Redeemer; the Church lives to bring humanity to this inexhaustible wellspring, of which she is depository and dispenser.

Lord Jesus Christ, Son of the living God, have mercy on me a sinner.

We can pray for and should pray for mercy, but what is mercy?

“Mercy. God’s loving care for all creatures, especially human beings, which invites us, in turn, to empathize with and alleviate the misery of others.”
Gerald O’Collins and Edward G. Farrugia, A Concise Dictionary of Theology (New York; Mahwah, NJ: Paulist Press, 2013), page 152.

We can also learn from Jesus as He teaches about this: “Go and learn what this means, ‘I desire mercy, and not sacrifice.’ For I came not to call the righteous, but sinners.” (Matthew 9:12-13) For Jesus wants us to have loving care for Him, by us showing and giving loving care for our brothers and sisters. This care/mercy for others is accomplished in the corporal works of mercy (feeding the hungry…) and also praying for others. We should both pray for ourselves and others to receive mercy.

Lord Jesus Christ, Son of the living God, have mercy on my family.
