List of points

Doesn't it move you to find the apostle John in his old age devoting the best part of one of his epistles to exhorting us to follow this divine teaching? The love that ought to exist amongst us Christians is born of God who is Love. 'Beloved let us love one another; for charity comes from God, and he who loves is born of God and knows God. He who has no love does not know God, for God is Love.' He focuses on fraternal charity because through Christ we have become children of God: 'See what love the Father has shown towards us, that we should be called children of God, and should be such.'

At the same time as he raps sharply on our consciences to make them sensitive to God's grace, he also insists that we have received a marvellous proof of the Father's love for men, 'By this was made manifest the charity of God for us, that God sent his only begotten Son into the world, so that we might live through him.' It was the Lord who took the initiative by coming out to meet us. He gave us this example so that we might join him in serving others, generously placing our hearts on the ground, as I am fond of saying, so that others may tread softly and find their struggle more pleasant. This is how we should behave because we have been made children of the same Father, that Father who did not hesitate to give us his dearly beloved Son.

Charity is not something we ourselves build up. It invades us along with God's grace, 'because he has loved us first'. We would do well to fill, to saturate ourselves with this most beautiful truth: 'If we are able to love God, it is because we have been loved by God.' You and I are able to lavish affection upon those around us, because we have been born to the Faith, through the Father's love for us. Ask God boldly for this treasure, for the supernatural virtue of charity, so that you may practise it even in the smallest details.

Too often we Christians have not known how to correspond to this gift. At times we have debased it, as if it could be confined to a soulless and cold almsgiving; or we have reduced it to more or less stereotyped good works. This distortion of charity was well expressed once by a sick woman when she commented with sad resignation, 'Yes, they treat me with "charity" here, but my mother used to look after me with affection.' A love that springs from the Heart of Christ could never countenance such distinctions.

In order that you might grasp this truth very clearly, I have preached on countless occasions that we do not have one heart to love God with and another with which to love men. This poor heart of ours, made of flesh, loves with an affection which is human and which, if it is united to Christ's love, is also supernatural. This, and no other, is the charity we have to cultivate in our souls, a charity which will lead us to discover in others the image of Our Lord.

St Leo the Great says that 'the term "neighbour" includes not only those with whom we have ties of friendship or family, but all our fellow men with whom we share a common nature… A single Creator has made us and given us our souls. We all live under the same sky and breathe the same air, and we live through the same days and nights. Although some people are good and others bad, some just and others unjust, God nevertheless is generous and kind towards all.'

We grow up as children of God by practising the new commandment. In the Church we learn to serve and not to be served, and we find we have the strength to love all mankind in a new way, which all will recognise as stemming from the grace of Christ. Our love is not to be confused with sentimentality or mere good fellowship, nor with that somewhat questionable zeal to help others in order to convince ourselves of our superiority. Rather, it means living in peace with our neighbour, venerating the image of God that is found in each and every man and doing all we can to get them in their turn to contemplate that image, so that they may learn how to turn to Christ.

Charity with everyone means, therefore, apostolate with everyone. It means we, on our part, must translate into deeds and truth the great desire of God 'who wishes all men to be saved and to come to the knowledge of truth'.

If we must also love our enemies (here I mean those who regard us as such, for I do not consider myself an enemy of anyone or of anything) we have all the more reason for loving those who are simply distant from us, those whom we find less attractive, those who seem the opposite of you or me on account of their language, culture or upbringing.

What kind of love are we talking about? Sacred Scripture uses the Latin word dilectio, to make us understand clearly that it does not simply mean the feeling of affection. It signifies, rather, a firm determination on the part of the will. Dilectio comes from electio, choice. I would add that, for Christians, loving means 'wanting to love', making up one's mind in Christ to work for the good of souls, without discrimination of any kind; trying to obtain for them, before any other good, the greatest good of all, that of knowing Christ and falling in love with him.

Our Lord spurs us on: 'Do good to those who hate you, pray for those who persecute and insult you.' We might not feel humanly attracted to those who would reject us were we to approach them. But Jesus insists: we must not return evil for evil; we must not waste any opportunities we have of serving them wholeheartedly, even if we find it difficult to do so; we must never cease keeping them in mind in our prayers.

This dilectio, this charity, becomes even more affectionate when its object is our brothers in the faith and particularly those who, by God's will, work close beside us: our parents, husband or wife, children, brothers and sisters, friends and colleagues, neighbours. Without this affection, which is a noble and pure human love directed towards God and based on him, there would be no charity.

I like to repeat what the Holy Spirit tells us through the prophet Isaiah, discite benefacere, learn how to do good. I like to apply this advice to all the different aspects of our interior struggle, because we can never consider our lives as Christians as something finished and complete. The Christian virtues develop as a consequence of real effort, each day.

Take any job in life; how do we set about learning it? First we find out what we want to achieve and what means we have to obtain it. Then we use those means, perseveringly, over and over again, until we have formed a well-rooted habit. As soon as we learn one thing, we discover other things hitherto unknown to us and they in turn stimulate us to continue working without ever giving up.

Charity towards our neighbour is an expression of our love of God. Accordingly, when we strive to grow in this virtue, we cannot fix any limits to our growth. The only possible measure for the love of God is to love without measure; on the one hand, because we will never be able to thank him enough for what he has done for us; and on the other, because this is exactly what God's own love for us, his creatures, is like: it overflows without calculation or limit.

In his Sermon on the Mount, Jesus teaches his divine command of charity to all who are ready to listen with an open mind. At the end, by way of summary, he says, 'Love your enemies, and do good to them, and lend to them, without any hope of return; then your reward will be a rich one, and you will be children of the most High, generous like him towards the thankless and unjust. Be merciful, then, as your Father is merciful.'

Mercy is more than simply being compassionate. Mercy is the overflow of charity, which brings with it also an overflow of justice. Mercy means keeping one's heart totally alive, throbbing in a way that is both human and divine, with a love that is strong, self-sacrificing and generous. Here is what St Paul has to say about charity in his hymn to this virtue, 'Charity is patient, is kind; charity feels no envy; charity is never perverse or proud, never insolent; does not claim its rights, cannot be provoked, does not brood over an injury; takes no pleasure in wrong-doing, but rejoices at the victory of truth; sustains, believes, hopes, endures, to the last.'

One of its first expressions is to initiate the soul into the ways of humility. When we sincerely see ourselves as nothing; when we understand that, without God's help, the weakest and most puny of creatures would be better than we are; when we see we are capable of every kind of error and every kind of abomination; when we realise we are sinners, even though we are earnestly struggling to turn our back on our many infidelities, how could we possibly think badly of others? Or how could we harbour fanaticism, intolerance or haughtiness in our hearts?

Humility leads us as it were by the hand to treat our neighbour in the best way possible, that is, being understanding towards everyone, living at peace with everyone, forgiving everyone; never creating divisions or barriers; and behaving — always! — as instruments that foster unity. Not in vain is there in the depths of man's being a strong longing for peace, for union with his fellow man, for a mutual respect for personal rights, so strong that it seeks to transform human relations into fraternity. This longing reflects something which is most deeply imprinted upon our human condition: since we are all children of God, our fraternity is not a cliche or an empty dream; it beckons as a goal which, though difficult, is really ours to achieve.

As Christians we must show that affection of this kind is in fact possible whatever the cynics or sceptics, those disappointed in love or those with a cowardly outlook on life might say. It may be quite difficult to be truly affectionate, for man was created free and he can rebel against God in a useless and bitter way. But it is possible and people can attain it, because it flows as a necessary consequence of God's love for us and our love for God. If you and I want it, Jesus also wants it. Then we will obtain a full and fruitful understanding of the meaning of suffering, sacrifice and unselfish dedication in ordinary life.

It would be naive to think that the demands of Christian charity are easy to fulfil. Our day to day experience of the affairs of men, even unfortunately within the Church itself, tells us a very different story. If love did not bid us keep silence, each could tell a lengthy tale of disunity, personal attacks, injustice, slander and intrigue. Let us admit it openly, and try for our part to apply the right solution to the problem, which should consist in our personal efforts not to wound or ill-treat anyone, and not to humiliate others when we have to correct them.

The problem of course is not new. Only a few years after Christ's Ascension into heaven, when most of the apostles were still alive and active and there was a wonderful atmosphere of faith and hope, there were already quite a number who had begun to lose their way, failing to follow the charity of their Master.

To the Corinthians St Paul writes, 'Do not these rivalries, these dissensions among you show that nature is still alive, that you are guided by human standards? When one of you says, I am for Paul, and another, I am for Apollo, are not these human thoughts,' of men who do not understand that Christ came to do away with all these divisions? 'Why, what is Apollo, what is Paul? Only the ministers of the God in whom your faith rests, who have brought that faith to each of you in the measure God granted.'

The Apostle is not condemning diversity. Each person has his own gift from God, some in one thing, some in another. These differences, however, must serve the good of the Church. I feel moved right now to ask Our Lord (and if you wish you can join in my prayer) not to permit uncharitableness to sow its cockle in the Church. Charity is the salt of the Christian apostolate. If it should lose its taste, how can we come to the world and proclaim: 'Here is Christ?'
