For this is the message you have heard from the beginning: we should love one another, unlike Cain who belonged to the evil one and slaughtered his brother. Why did he slaughter him? Because his own works were evil, and those of his brother righteous. Do not be amazed, (then,) brothers, if the world hates you. We know that we have passed from death to life because we love our brothers. Whoever does not love remains in death. Everyone who hates his brother is a murderer, and you know that no murderer has eternal life remaining in him. The way we came to know love was that he laid down his life for us; so we ought to lay down our lives for our brothers. If someone who has worldly means sees a brother in need and refuses him compassion, how can the love of God remain in him? Children, let us love not in word or speech but in deed and truth.
Pope John Paul II
"Walk as children of light ... and try to learn what is pleasing to the Lord. Take no part in the unfruitful works of darkness" (Eph 5:8, 10-11). In our present social context, marked by a dramatic struggle between the "culture of life" and the "culture of death", there is need to develop a deep critical sense, capable of discerning true values and authentic needs.
"We are writing you this that our joy may be complete" (1 Jn 1:4). The revelation of the Gospel of life is given to us as a good to be shared with all people: so that all men and women may have fellowship with us and with the Trinity (cf. 1 Jn 1:3). Our own joy would not be complete if we failed to share this Gospel with others but kept it only for ourselves.
The one who accepted "Life" in the name of all and for the sake of all was Mary, the Virgin Mother; she is thus most closely and personally associated with the Gospel of life. Mary's consent at the Annunciation and her motherhood stand at the very beginning of the mystery of life which Christ came to bestow on humanity (cf. Jn 10:10). Through her acceptance and loving care for the life of the Incarnate Word, human life has been rescued from condemnation to final and eternal death.
For this reason, Mary, "like the Church of which she is the type, is a mother of all who are reborn to life. She is in fact the mother of the Life by which everyone lives, and when she brought it forth from herself she in some way brought to rebirth all those who were to live by that Life".138As the Church contemplates Mary's motherhood, she discovers the meaning of her own motherhood and the way in which she is called to express it. At the same time, the Church's experience of motherhood leads to a most profound understanding of Mary's experience as the incomparable model of how life should be welcomed and cared for.
