While the modern world is continually changing its values depending on what's popular at the moment, the Catholic Church has never ceased in its defense of every human life, from conception to natural death.
This includes the Second Vatican Council, which did not soften Church teaching, but reinforced it.
In particular, Vatican II was strong in its opposition to abortion, as well as all offenses against human life. The Church's stance is laid out in the document Gaudium et Spes.
The ministry of safeguarding life
Not only did the Church speak out against abortion, but also the "ministry" of safeguarding life, placing upon all Catholics an obligation to do everything in their power to protect life.
One of the most important ways to safeguard human life at conception is to simultaneously protect the dignity of marital love.
This is no small task, but every Catholic can rest assured that the Church has not, and will not be changing her stance on such an issue.
