If the unborn is a human person, no justification for abortion is adequate.

You may be a fantastic person, and you may have some wonderful religious views that might even turn out to be true, but the religion you'd be following would not be Christianity.

God created man to share friendship with Him and share in His happiness.

If Darwinism is true, then there is no purpose or meaning to life, there is no morality, there's no qualitative difference between humans and animals, there's no life after death, and there's no purpose to human history. Now, are you trying to tell me that it doesn't really matter if people believe we evolved or not?

Something good made something bad possible (though not inevitable). Humans, however, didn't use their freedom well. Instead of using it to honor God in friendship, they used it to rebel.

If man is not special, if he's not deeply different from any other thing, then there's no good reason not to treat him just like any other thing when it's convenient for us to do so.

Nowadays, people have a habit of relativizing religion, reducing it to "your truth" versus "my truth" versus "their truth," and that's the end of it.
