A mother and father each bring something unique and irreplaceable to child-rearing that the other cannot.
A person who denies even one article of our faith could not be a Catholic; for truth is one and we must accept it whole and entire or not at all.
As an ancient axiom states, the Church makes the Eucharist, and the Eucharist makes the Church.
Christian morality and God's law are not arbitrary, but are specifically given to us for our happiness.
Denying evil corrupts us spiritually and psychologically. Rationalizing our own evil is even more destructive.
Freedom comes from being moral. Slavery to sin arises from being immoral.
God created man and woman, equal to each other as persons and in dignity. Each is completely human and is meant to complement the other in a communion of persons, seen most evidently in marriage.
Human freedom is more than a capacity to choose between this and that. It is the God-given power to become who he created us to be and so to share eternal union with him.
Instinctively, we turn to holy people for their prayers because they seem nearer to God. Why would we stop asking saints for their prayers after they die? If we believe they are in heaven, would not their prayers be even more effective?
It is false and absurd to say that we should remain in error after we have discovered it.
Not to be deceived in matters of faith, we must always distinguish very carefully between the abuses to which a devotion may lead and the truths upon which the devotion rests.
Scripture alone is insufficient. Authoritative teaching is also needed.
Since we have the obligation to obey our conscience, we also have the great responsibility to see that it is formed in a way that reflects the true moral good.
Some acts are always wrong--that is, intrinsically evil--and may never be done, no matter what the intention or the circumstances.
The Bible is not a scientific textbook and should never be read as such; rather it reveals what God wants us to know for the sake of our salvation.
The Church alone has the right to make laws concerning the Sacrament of marriage, though the state also has the right to make laws concerning the civil effects of the marriage contract.
The Church can, when necessary, change the laws it has itself made, but it cannot change the laws that Christ has made.
The name of God must never be used to support immoral acts.
The preservation of lawful authority, good order in society, the protection of others, and sometimes even the good of the guilty one himself, require that crimes be justly punished.
There can be only one true religion, because a thing cannot be false and true at the same time, and, therefore, all religions that contradict the teaching of the true Church must teach falsehood.
There is no bigotry in treating genuinely different things differently.
There is no intrinsic conflict between science and religion.
To say that we should remain in a false religion because we were born in it is as untrue as to say we should not heal our bodily diseases because we were born with them.
We believe that every person is precious, that people are more important than things, and that the measure of every institution is whether it threatens or enhances the life and dignity of the human person.
We must not seek martyrdom, though we must endure it when it comes.
We need to safeguard property rights, pay our debts, and fulfill obligations freely incurred.
While the law may not draw classifications based upon mere thoughts, beliefs, or inclination, it can and routinely does distinguish between types of conduct.
