62 Yet this call to love could be misunderstood. Saint Paul, recognizing the temptation of the earliest Christian communities to form closed and isolated groups, urged his disciples to abound in love “for one another and for all” ( 1 Thess 3:12). In the Johannine community, fellow Christians were to be welcomed, “even though they are strangers to you” ( 3 Jn 5). In this context, we can better understand the significance of the parable of the Good Samaritan: love does not care if a brother or sister in need comes from one place or another. For “love shatters the chains that keep us isolated and separate; in their place, it builds bridges. Love enables us to create one great family, where all of us can feel at home… Love exudes compassion and dignity”.
