You’re missing the obvious. Whether individuals of yore recognized the Church’s teaching on the sacredness and dignity of human life is not the point. The point is that marriage has always been tied to the natural capacity to procreate.
Sure, but my point is that Catholics shouldn’t act as if the history of marriage is on their side. People have usually agreed in the past that marriage is tied to children, but the justifications for this were very different than today.
If two groups of people do the same thing but for different reasons, then there is no actual agreement between them. It’s dishonest to argue otherwise.
I also think your example proves too much. IF marriage in earlier times was simply to unite families or obtain and extend wealth, it was in no way related to what marriage is said to be today in secular society.
I’m not sure in which sense this is “proving too much”. This illustrates what I was talking about: The definition of marriage has, in fact, changed over time. It used to be for the sake of individual families, now it’s for the sake of society.
The union of man and woman is naturally oriented towards the creation of new life, assuming that there are no barriers, such as through injury or disease.
But what happens when there
are barriers such as diseases or conditions that cause impotence/infertility? To ignore these possibilities is terribly arbitrary. I could do the same thing for gay marriage: If we disregard the biological barriers of two people of the same sex, they could produce new life. You could argue for the “potential” of anything as long as you’re willing to ignore limitations arbitrarily.
And it isn’t just disease one needs to worry about. If a woman gets married in her 40s, for example, she is much less likely to procreate than a younger woman. Unlike future medical conditions, this is a factor that is entirely predictable. It would be a simple matter for the Church to forbid marriage to sufficiently old women on the grounds that they will likely not procreate.
If marriage is simply between Person 1 and Person 2, the rights of the child are ignored, or worse relegated to meet the needs of the couple.
I don’t follow. The rights of children are not contingent on one’s definition of “marriage”; the worst-case scenario is that you would have to tweak the phrasing of existing rights. Marriage as an institution could be eliminated tomorrow and there would still be no legal or moral ground for neglecting children’s rights.
Being a child isn’t like being, say, a student, where your status depends on the existence of a social institution (in the case of students, public schools). You’re still either a child or not independently of the marriage of your parents.
If non-Catholic marriage is not about children at all, as you suggest, where is the historical evidence supporting your assertion?
The rebuttal to the remainder of your post is easy, because this is simply not what I stated, neither for past nor current marriages.
You seem fixated on the idea that if a couple can’t reproduce, or doesn’t want to reproduce, they must not wish to care for children. That is emphatically not the case. Many straight couples don’t wish to endure a pregnancy and yet wish to adopt children. Just because you don’t want to procreate doesn’t mean your paternal or maternal instinct withers away.
