Deus Caritas Est...

Married love particularly reveals its true nature and nobility when we realize that it takes its origin from God, who "is love," the Father "from whom every family in heaven and on earth is named."

Marriage, then, is far from being the effect of chance or the result of the blind evolution of natural forces. It is in reality the wise and provident institution of God the Creator, whose purpose was to effect in man His loving design. As a consequence, husband and wife, through that mutual gift of themselves, which is specific and exclusive to them alone, develop that union of two persons in which they perfect one another, cooperating with God in the generation and rearing of new lives.

The marriage of those who have been baptized is, in addition, invested with the dignity of a sacramental sign of grace, for it represents the union of Christ and His Church.

What Marriage Is...

This love is above all fully human, a compound of sense and spirit. It is not, then, merely a question of natural instinct or emotional drive. It is also, and above all, an act of the free will, whose trust is such that it is meant not only to survive the joys and sorrows of daily life, but also to grow, so that husband and wife become in a way one heart and one soul, and together attain their human fulfillment.

It is a love which is total—that very special form of personal friendship in which husband and wife generously share everything, allowing no unreasonable exceptions and not thinking solely of their own convenience. Whoever really loves his partner loves not only for what he receives, but loves that partner for the partner's own sake, content to be able to enrich the other with the gift of himself.

Married love is also faithful and exclusive of all other, and this until death. This is how husband and wife understood it on the day on which, fully aware of what they were doing, they freely vowed themselves to one another in marriage. Though this fidelity of husband and wife sometimes presents difficulties, no one has the right to assert that it is impossible; it is, on the contrary, always honorable and meritorious. The example of countless married couples proves not only that fidelity is in accord with the nature of marriage, but also that it is the source of profound and enduring happiness.

Finally, this love is fecund. It is not confined wholly to the loving interchange of husband and wife; it also contrives to go beyond this to bring new life into being. "Marriage and conjugal love are by their nature ordained toward the procreation and education of children. Children are really the supreme gift of marriage and contribute in the highest degree to their parents' welfare."

What Marriage Isn't...

The Church, nevertheless, in urging men to the observance of the precepts of the natural law, which it interprets by its constant doctrine, teaches that each and every marital act must of necessity retain its intrinsic relationship to the procreation of human life.

This particular doctrine, often expounded by the magisterium of the Church, is based on the inseparable connection, established by God, which man on his own initiative may not break, between the unitive significance and the procreative significance which are both inherent to the marriage act.

The reason is that the fundamental nature of the marriage act, while uniting husband and wife in the closest intimacy, also renders them capable of generating new life—and this as a result of laws written into the actual nature of man and of woman. And if each of these essential qualities, the unitive and the procreative, is preserved, the use of marriage fully retains its sense of true mutual love and its ordination to the supreme responsibility of parenthood to which man is called. We believe that our contemporaries are particularly capable of seeing that this teaching is in harmony with human reason.

[...]

Therefore We base Our words on the first principles of a human and Christian doctrine of marriage when We are obliged once more to declare that the direct interruption of the generative process already begun and, above all, all direct abortion, even for therapeutic reasons, are to be absolutely excluded as lawful means of regulating the number of children. Equally to be condemned, as the magisterium of the Church has affirmed on many occasions, is direct sterilization, whether of the man or of the woman, whether permanent or temporary.

Similarly excluded is any action which either before, at the moment of, or after sexual intercourse, is specifically intended to prevent procreation—whether as an end or as a means.

Neither is it valid to argue, as a justification for sexual intercourse which is deliberately contraceptive, that a lesser evil is to be preferred to a greater one, or that such intercourse would merge with procreative acts of past and future to form a single entity, and so be qualified by exactly the same moral goodness as these. Though it is true that sometimes it is lawful to tolerate a lesser moral evil in order to avoid a greater evil or in order to promote a greater good," it is never lawful, even for the gravest reasons, to do evil that good may come of it —in other words, to intend directly something which of its very nature contradicts the moral order, and which must therefore be judged unworthy of man, even though the intention is to protect or promote the welfare of an individual, of a family or of society in general. Consequently, it is a serious error to think that a whole married life of otherwise normal relations can justify sexual intercourse which is deliberately contraceptive and so intrinsically wrong.

Natural Family Planning...

If therefore there are well-grounded reasons for spacing births, arising from the physical or psychological condition of husband or wife, or from external circumstances, the Church teaches that married people may then take advantage of the natural cycles immanent in the reproductive system and engage in marital intercourse only during those times that are infertile, thus controlling birth in a way which does not in the least offend the moral principles which We have just explained.

Neither the Church nor her doctrine is inconsistent when she considers it lawful for married people to take advantage of the infertile period but condemns as always unlawful the use of means which directly prevent conception, even when the reasons given for the later practice may appear to be upright and serious. In reality, these two cases are completely different. In the former the married couple rightly use a faculty provided them by nature. In the later they obstruct the natural development of the generative process. It cannot be denied that in each case the married couple, for acceptable reasons, are both perfectly clear in their intention to avoid children and wish to make sure that none will result. But it is equally true that it is exclusively in the former case that husband and wife are ready to abstain from intercourse during the fertile period as often as for reasonable motives the birth of another child is not desirable. And when the infertile period recurs, they use their married intimacy to express their mutual love and safeguard their fidelity toward one another. In doing this they certainly give proof of a true and authentic love.

Consequences of Contraception...

Not much experience is needed to be fully aware of human weakness and to understand that human beings—and especially the young, who are so exposed to temptation—need incentives to keep the moral law, and it is an evil thing to make it easy for them to break that law. Another effect that gives cause for alarm is that a man who grows accustomed to the use of contraceptive methods may forget the reverence due to a woman, and, disregarding her physical and emotional equilibrium, reduce her to being a mere instrument for the satisfaction of his own desires, no longer considering her as his partner whom he should surround with care and affection.

Sign of Contradiction...

It is to be anticipated that perhaps not everyone will easily accept this particular teaching. There is too much clamorous outcry against the voice of the Church, and this is intensified by modern means of communication. But it comes as no surprise to the Church that she, no less than her divine Founder, is destined to be a "sign of contradiction." She does not, because of this, evade the duty imposed on her of proclaiming humbly but firmly the entire moral law, both natural and evangelical.

Since the Church did not make either of these laws, she cannot be their arbiter—only their guardian and interpreter. It could never be right for her to declare lawful what is in fact unlawful, since that, by its very nature, is always opposed to the true good of man.

Spell It Out...

And now, beloved sons, you who are priests, you who in virtue of your sacred office act as counselors and spiritual leaders both of individual men and women and of families—We turn to you filled with great confidence. For it is your principal duty—We are speaking especially to you who teach moral theology—to spell out clearly and completely the Church's teaching on marriage.

New Encyclical clears up longstanding question... "Jesus was not Spartacus"

It also says a lot of other stuff. You can read it online here

Disclaimer: The following are some quotes I found and liked while skimming this lunchtime. I haven't read it all yet, and this is not supposed to constitute a summary.

Faith is not merely a personal reaching out towards things to come that are still totally absent: it gives us something. It gives us even now something of the reality we are waiting for, and this present reality constitutes for us a “proof” of the things that are still unseen. Faith draws the future into the present, so that it is no longer simply a “not yet”. The fact that this future exists changes the present; the present is touched by the future reality, and thus the things of the future spill over into those of the present and those of the present into those of the future.

Freedom presupposes that in fundamental decisions, every person and every generation is a new beginning. Naturally, new generations can build on the knowledge and experience of those who went before, and they can draw upon the moral treasury of the whole of humanity. But they can also reject it, because it can never be self-evident in the same way as material inventions. The moral treasury of humanity is not readily at hand like tools that we use; it is present as an appeal to freedom and a possibility for it. This, however, means that:

a) The right state of human affairs, the moral well-being of the world can never be guaranteed simply through structures alone, however good they are. Such structures are not only important, but necessary; yet they cannot and must not marginalize human freedom. Even the best structures function only when the community is animated by convictions capable of motivating people to assent freely to the social order. Freedom requires conviction; conviction does not exist on its own, but must always be gained anew by the community.

b) Since man always remains free and since his freedom is always fragile, the kingdom of good will never be definitively established in this world. Anyone who promises the better world that is guaranteed to last for ever is making a false promise; he is overlooking human freedom. Freedom must constantly be won over for the cause of good. Free assent to the good never exists simply by itself. If there were structures which could irrevocably guarantee a determined—good—state of the world, man's freedom would be denied, and hence they would not be good structures at all.

Let us say once again: we need the greater and lesser hopes that keep us going day by day. But these are not enough without the great hope, which must surpass everything else. This great hope can only be God, who encompasses the whole of reality and who can bestow upon us what we, by ourselves, cannot attain. The fact that it comes to us as a gift is actually part of hope. God is the foundation of hope: not any god, but the God who has a human face and who has loved us to the end, each one of us and humanity in its entirety. His Kingdom is not an imaginary hereafter, situated in a future that will never arrive; his Kingdom is present wherever he is loved and wherever his love reaches us. His love alone gives us the possibility of soberly persevering day by day, without ceasing to be spurred on by hope, in a world which by its very nature is imperfect. His love is at the same time our guarantee of the existence of what we only vaguely sense and which nevertheless, in our deepest self, we await: a life that is “truly” life.

Fantastic news (if it is true)...

ROME, Nov 15, 2007 / 09:41 am (CNA).- The Italian newspaper La Repubblica revealed today that Pope Benedict XVI has finalized his second encyclical on the subject of Christian hope, and that it should be published before Christmas, during Advent.

Benedict’s first encyclical, “Deus Caritas est”, was signed on Christmas Day 2005 and by the following month had been published in eight languages. His second encyclical is tentatively titled "Spe Salvi” (Saved by Hope) and takes its inspiration from St. Paul’s letter to the Romans, the newspaper reported. The potential title comes from the 24th verse of the eighth chapter of St. Paul's letter, which reads: "Because we have been saved by hope."

According to La Repubblica, the Holy Father wants to "reach the hearts of Christians and invite them to have hope, without being thrashed by pessimism."

The document, according to the same source, is being translated into several languages and could be signed by the Holy Father on December 8, the Solemnity of the Immaculate Conception and the anniversary of the close of Vatican II.
