St. Augustine wrote a whole treatise...

“St. Augustine wrote a whole treatise on Conjugal Adultery, in which he declared, ‘Intercourse with one’s legitimate wife is unlawful and wicked whenever the conception of offspring is prevented.’”

Worship pleasing to God...

"Worship pleasing to God can never be a purely private matter, without consequences for our relationships with others: it demands a public witness to our faith. Evidently, this is true for all the baptized, yet it is especially incumbent upon those who, by virtue of their social or political position, must make decisions regarding fundamental values, such as respect for human life, its defence from conception to natural death, the family built upon marriage between a man and a woman, the freedom to educate one's children and the promotion of the common good in all its forms (230). These values are not negotiable. Consequently, Catholic politicians and legislators, conscious of their grave responsibility before society, must feel particularly bound, on the basis of a properly formed conscience, to introduce and support laws inspired by values grounded in human nature (231). There is an objective connection here with the Eucharist (cf. 1 Cor 11:27-29). Bishops are bound to reaffirm constantly these values as part of their responsibility to the flock entrusted to them (232)."
~ Sacramentum Caritatis, Pope Benedict XVI ~

The real question today...

“The real question today is not when human life begins, but, What is the value of human life? The abortionist who reassembles the arms and legs of a tiny baby to make sure all its parts have been torn from its mother's body can hardly doubt whether it is a human being. The real question for him and for all of us is whether that tiny human life has a God-given right to be protected by the law— the same right we have.”
~ Ronald Reagan – Abortion and the Conscience of the Nation ~

It is categorically impossible...

"It is categorically impossible for the same person to state that he or she believes simultaneously both what the Catholic Church teaches and that abortion is just a choice."
~ Bishop Robert Vasa on Nancy Pelosi: There are just and unjust choices — church teaching helps ~
