[... Are you saying that the Supreme Court of the United States really has no moral authority over just what constitutes a human being?...]
Without the counsel of Scripture, the Supreme Court cannot be trusted to make moral decisions.
So the answer is yes.
Without the counsel of Scripture, the Supreme Court cannot be trusted to make moral decisions.
Being an originalist, I do not think the SCOTUS should be making moral decisions, that's what the liberal "living document" types do.
The job of the court is to look to the constitution, as written. They do not need any moral guidance, either from "evolving standards of decency", or the Bible. It ain't their job.
If this is a problem, then it is a problem in the Constitution, and as an originalist, the Constitution is clear on how it can be changed.
I don't want nine black robed judges handing down word on high about morality. That's a liberal notion. Follow the constitution, as written, or change the parts unliked via amendment.
