Greetings all, Groypxis here, back from the dead.
The question today is, would it be sinful to marry and procreate with an anthro?
Now, if something is sinful, it goes against God's law and it goes against the Catholic Church.
Most individuals moral objection to this would be something along the lines of "She's an animal!"
However.
In Catholic Theology, what mostly separates Man from Beast, and Demon from Man, is intelligence.
A Man is Man because he has an intellect and will, an animal does not, and is a creature of pure instinct.
Now, obviously anthros are intelligent and have a will of their own, and by extension, likely have a soul (this will be important later). While anthros may also have an instinctual aspect to their personality and behavior (this may be attractive to some, including myself) but they do have intellect and will, therefure, they can in fact be classified in the category of "human".
Now that we've established that Anthros are more human than beast, we can move on to the question of marriage and procreation.
Now, at first glace, it seems there should be no reason to not be able to wed with your beloved anthro furry waifu, but first we must ask: Why must we wed?
God Instituted marriage as a healthy way to establish the family. After all, the end goal of marriage is procreation. That is all. God's first commandment to us was " Be fruitful and multiply." So to engage in marriage with an anthro, you must be able to procreate with her.
Now, if we assume that her womb is capable of conceiving with human sperm, which logically, being humanoid, shouldn't be too much of an issue, the real problem at hand is the state of the child.
